SERIES No forgotten keys No locked-in workers No inadvertent machinery operation The safety door switch with key SG-B2 series locks and unlocks doors with keys. When an operator takes a key into a hazardous area, the safety door switch will not lock, and the equipment will stop, ensuring operator safety by preventing personnel from being closed inside the hazardous area and preventing equipment from starting to operate. Safety worker Safety door switch with key SG-B2 series ACTION 1 ACTION 1 ACTION 2 ACTION Door unlocked 2 Key brought into the hazardous area Hazards of the system and robot are isolated by the safety guard. The worker uses the key to unlock the door and disables the system from starting unexpectedly, then removes the key and brings it into the hazardous area. The system remains off until the worker walks out the door and locks the door with the key. This enables the worker carrying the key to work safely in the hazardous area. Connectable safety relay units Additionally, the key selector switch SG-D1 series can be used to switch equipment modes and unlock door locks with a single key.

When a worker needs to work inside the hazardous area for maintenance, the worker unlocks the safety guard using a key, disables the system from starting (1), removes the key and brings it into the hazardous area, and then changes the operation mode of each system to maintenance mode (2). While the worker is carrying out maintenance work in the hazardous area, the safety guard cannot be locked and the system cannot be turned on. This enables the worker to work safely in the hazardous area. Energy-saving design, no power supply required Since doors are locked and unlocked with a key, there is no need to supply power to the safety door switch. Head removal detection function Head removal detection function is employed in the SG-B2. With this innovative function, the monitor circuit (41-42) turns off when the head is removed from the switch, such as when removing the head to change the head direction. With the head installed on the switch, monitor circuits 41-42 and 51-52 operate in synchronization while the key locks / unlocks the actuator. When the head is removed, 41-42 turns off and 51-52 turns on. This disagreement is detected by the head removal detection function.

Push to lock Turn to reset The product line includes a SEMI emergency off (EMO) switch. SEMI emergency off (EMO) switch Pushbutton type SEMI semiconductor industry safety standards SEMI standards comprise a series of guidelines put together by an industry group consisting of manufacturers of semiconductor manufacturing equipment, flat-panel displays, and associated materials. In the semiconductor industry, this guidelines have achieved the status of de facto international standards. Section 12.1 of the SEMI standards (S2 0706) states, “Equipment should incorporate an emergency off (EMO) circuit. When the EMO actuator (button) is triggered, the equipment should transition to a safe state in which no new hazard is posed to workers or equipment.” This provision likely stems from the need to address the possibility of secondary hazards that could occur when processing power and other inputs are stopped, reflecting the industry’s extensive use of materials such as solvents and chemicals, many of which contain hazardous or toxic substances. Consequently, SEMI standards require that normal emergency stop switches, which shut off the supply of energy, including power, be augmented with separate emergency off switches that shut off only the portion of the load that created the hazardous state while maintaining operation of other safety-related equipment (smoke detectors, gas / water leak detectors, pressure measurement equipment, etc.). When there is the possibility that the emergency off switch could be operated mistakenly, a guard must be installed and the switch must use direct opening operation. The button must be red with a yellow background, and the switch itself must include the letters “EMO.”  When installing a SEMI emergency off (EMO) switch on semiconductor manufacturing equipment, it should be installed at a height of 838 to 1,638 mm 32.992 to 64.488 in. (SEMI S8-0705)  According to SEMI standards, the EMO emergency stop switch must be installed within 3 m 9.843 ft of the work location.

When both SELV (safety extra low voltage) or PELV (protective extra low voltage) circuits and other circuits (such as 230 V AC circuits) are used for the solenoid power and contact circuits at the same time, the SELV or PELV requirements are not met any more. 2) The actuator locking strength is rated at 500 N of static load. Do not apply a load higher than the rated value. Do not apply a load higher than the rated value. When a higher load is expected to work on the actuator, provide an additional system consisting of another safety switch without lock (such as the SG-A1 safety switch) or a sensor to detect door opening and stop the machine.

Be sure to read the instruction manual attached to the product prior to its use. SG-B1 SG-A1 Safety door switch with key SG-B2 Enable grip switch • In order to avoid electric shock or fire, turn the power off before installation, removal, wire connection, maintenance, or inspection of the safety switch. • If relays are used in the circuit between the safety switch and the load, consider the danger and use safety relays, since welding or sticking contacts of standard relays may invalidate the functions of the safety switch. • Do not place a PLC in the circuit between the safety switch and the load. Safety and security can be endangered in the event of a malfunction of the PLC. • Do not disassemble or modify the safety switch, otherwise a breakdown or an accident may occur. • Do not install the actuator in a location where the human body may come in contact. Otherwise injury may occur. • Magnet lock type is locked when energized, and unlocked when de-energized. When energization is interrupted due to wire disconnection or other failures, the safety switch may be unlocked causing possible danger to the operators. Magnet lock type must not be used in applications where locking is strictly required for safety. Perform a risk assessment and determine whether solenoid lock type is appropriate. Both series SG-C1 Emergency stop switch SG-E1 Key selector switch • Regardless of door types, do not use the safety switch as a door stop. Install a mechanical door stop at the end of the door to protect the safety switch against excessive force. • Do not apply external force on the actuator while unlocking, otherwise the actuator may not be unlocked. • Do not apply excessive shock to the safety switch when opening or closing the door. A shock to the safety switch exceeding 1,000 m/s2 may cause damage to the safety switch. • If the operating atmosphere is contaminated, use a protective cover to prevent the entry of foreign objects into the safety switch through the actuator entry slots. Entry of a considerable amount of foreign objects into the safety switch may affect the mechanism of the safety switch and cause a malfunction. • Do not store the safety switches in a dusty, humid, or organic-gas atmosphere, or in an area subjected to direct sunlight. • Use proprietary actuators only. When other actuators are used, the safety switch may be damaged. SG-B1 series SG-D1 20 • The locking strength is rated at 500 N. Do not apply a load higher than the rated value. When a higher load is expected, provide an additional system consisting of another safety switch without lock (such as the SG-A1 safety switch) or a sensor to detect door opening and stop the machine. • Regardless of door types, do not use the safety switch as a door lock. Install a separate lock using a latch or other measures. • While the solenoid is energized, the switch temperature rises approximately 35 °C 95 °F above the ambient temperature (to approximately 85 °C 185 °F while the ambient temperature is 50 °C 122 °F). Do not touch to prevent burns. If cables come into contact with the switch, use heat-resistant cables. • Bouncing will occur on the lock monitor contact during locking and unlocking (reference value: 20 ms). • Although the SG-K11 / SG-K12 / SG-K12A actuators alleviate shock when the actuator enters a slot in the safety switch, make sure that excessive shock is not applied. If the rubber bushings become deformed or cracked, replace with new ones. SG-A1 series • Cover the unused actuator entry slot using the slot plug supplied with the safety switch. Minimum radius of hinged door • When using the safety switch on hinged doors, refer to the minimum radius of doors shown below. When using on doors with small minimum radius, use the angle adjustable actuator (SG-K13 / SG-K14). Note: The values indicated in the figures below assume that there is no 6*.6*.$ mechanical interference between the actuator and the safety switch when the door is opened or closed. Because deviation or dislocation of hinged doors may occur in actual applications, make sure of the correct operation before installation. 0 0  LQLP P XP  LQLP  XP P UDG 'RRUKLQJH When using the right-angle actuator / SG-K12A) P (SG-K12  LXV P UDG   LQ  LXV 'RRUKLQJH  LQ SG-B1 series 6*.6*.$ 0 L  QLP  XP P P UD G   LXV  LQ 0 L  QLP X  P PU P  DGLX 'RRUKLQJH   V LQ 'RRUKLQJH 6*.6*.$ 0  LQLP P XP P UDG  LXV  LQ 'RRUKLQJH 0  LQLP  XP P P UDG   LXV  LQ 'RRUKLQJH SG-A1 series 6*.6*.$ SG-K12 0 L  QLP X  SG-K12 P PU M P DG ini  LX 23 mu  V 0 m m raLQ m d 9 iu M ini .05 s 23 mu 5 i n 0 m m ra m d 9. ius 05 SG-K12 5 in 0 L  QLP X  P PU MP D 'RRUKLQJH 2 inim GLXV 30 um  m m radLQ 9. ius Door hinge Mi 0 55 23 nimu in 0 m m ra m 9. dius Door hinge 05 5 in SG-K12 Min 16 imum 0 m ra m dius 6.2 Min 99 in i 16 mum 0 m ra m dius 6.2 99 in M rad inim 16 ius um 0m m M 6.2 rad inimu 99 in 16 ius m 0m m 6.2 99 in 'RRUKLQJH Door hinge Door hinge Door hinge Door hinge Door hinge Door hinge SG-B1SERIES / SG-A1SERIES Precautions for proper use 50 mm 1.969 in Door hinge Minim adjustment 50 mm 9 in Door hinge the1.96actuator • When the door hinge is on the extension line of Label SG-K13 mounting surface: 70 mm 2.756 in SG-K13 • When the door hinge is on the extension SG-K14line of the safety switch SG-K14 surface: 50 mm 1.969 in Minimum radius SG-B1 series 50 mm 1.969 in • Mount the safety switch on a fixed piece of machinery or guard and the actuator on a hinged door.

When both SELV (safety extra low voltage) or PELV (protective extra low voltage) circuits and other circuits (such as 230 V AC circuits) are used for the solenoid power and contact circuits at the same time, the SELV or PELV requirements are not met any more. 3) The actuator locking strength is rated at 1,400 N of static load. Do not apply a load higher than the rated value. When a higher load is expected to work on the actuator, provide an additional system consisting of another safety switch without lock (such as the SG-A1 safety switch) or a sensor to detect door opening and stop the machine. • Regardless of door types, do not use the safety switch as a door stop. Install a mechanical door stop at the end of the door to protect the safety switch against excessive force. • Do not apply excessive shock to the safety switch when opening or closing the door. A shock to the safety switch exceeding 1,000 m/s2 may cause damage to the safety switch. • If the operating atmosphere is contaminated, use a protective cover to prevent the entry of foreign objects into the safety switch through the actuator entry slots. Entry of a considerable amount of foreign objects into the safety switch may affect the mechanism of the safety switch and cause a malfunction. • Cover the unused actuator entry slot using the slot plug supplied with the safety switch. • Do not store the safety switches in a dusty, humid, or organic-gas atmosphere, or in an area subjected to direct sunlight. • Use proprietary actuators only. When other actuators are used, the safety switch may be damaged. Do not cut, machine, or otherwise modify actuators. Doing so may cause equipment failure. • Do not open the lid of the safety switch. Loosening the screws may damage the safety switch. • The locking strength is rated at 1,400 N. Do not apply a load higher than the rated value. When a higher load is expected, provide an additional system consisting of another safety switch without lock or a sensor to detect door opening and stop the machine. • Regardless of door types, do not use the safety switch as a door lock. Install a separate lock using a latch or other measures. • Although the SG-K21A / SG-K22A actuators alleviate the shock when the actuator enters the slot on the safety switch, make sure that excessive shock is not applied. If the rubber bushings become deformed or cracked, replace with new ones. SG-B2 SERIES Precautions for proper use • Do not mount the safety switch facing down as shown in the figure below.

Configure the enabling system so that the machine can operate when the switch is in position 2 and an additional “start” is pushed to initiate the operation. • In order to ensure safety of the control system, connect each pair of the contacts of the 3 position enabling switch (terminal No. NO1-C1 and NO2-C2) to a discrepancy detection circuit such as a safety relay module. (ISO13849-1) • The base and the plastic part of rubber boot frame are made of glass-reinforced ABS / PBT. The rubber boot is made of silicone rubber. The screw is made of iron. When cleaning the SG-C1 series, use a detergent compatible with the materials • As for momentary pushbutton switch and key selector switch of additional control unit, do not connect NO and NC contacts of a microswitch to different voltages or different power sources to prevent a dead short-circuit. • Do not operate key selector switch of additional control unit without completely insertion of the key. • The rubber boot may deteriorate depending on the operating environment and conditions. SG-B1 SG-A1 Emergency stop switch Electric shock protection class Operating frequency • In order to avoid electric shock or fire, turn the power off before installation, removal, wire connection, maintenance, or inspection of the safety switch. • Do not disassemble or modify the grip switch. • When using the SG-C1 series for safety-related equipment in a control system, refer to the safety standards and regulations in each country and region depending on the application purpose of the actual machines and installations to make sure of correct operation. Also, perform risk assessment to make sure of safety before starting operation. • Do not tie the grip switch around the button with a tape or string to keep the switch in position 2. Doing so will prevent the grip switch from functioning as designed and is extremely dangerous. Systems that stop operation after the grip has been operated for a certain period of time and require the operator to grip it again are effective in preventing circumvention of the device’s intended purpose. • Please note that permanent installation of the grip switch at the machine is inadmissible.
