Roller The roller actuator is made of hardened stainless steel and excels in resistance to wear. Lever The Roller Lever Switch employs a system which allows selection of the operation of only one side (left or right) or both sides without use of any tools. Easy-maintenance Block Mounting Block mounting makes it possible to easily assemble or disassemble the head, switch body, and receptacle of the D4A-@N by tightening or loosening the attached screws. With the Roller Lever Switch, the lever can be installed anywhere in a 360° range (180° if the lever is reversed and attached to the shaft). Head Oil Seal Improved sealing property is ensured with a double-seal construction (a oil seal plus an X-ring seal). Operating Position Mark (arrow) Actuator Bearings The copper-alloy bearings ensure long life expectancy. Switch Box Boasts long life expectancy (50 million mechanical operations or more with the 2-pole Double-break Switches and 30 million mechanical operations or more with the DPDT Double-break Switches). Receptacle The plug-in type receptacle provides adequate space for wiring. Switch box Ground Terminal Screw A ground terminal is provided to enhance safety. Conduit Opening *1, *2 G 1/2 conduit threads featuring high sealing property are used. (Refer to Limit Switch Connectors for details on SC connectors). A terminal box with 1/2-14NPT conduit threads is also available on request. Switch Box Screw Sealed Gasket The employed full-cover method prevents the gasket from direct exposure to oil or water spray. Receptacle A Phillips screw is used to secure the switch housing for ease of use, and features a measure to prevent the screw from coming off. Note: 1. NBR is used in rubber components. Fluoro-rubber sealed types use fluoro-rubber. 2. For Roller Levers, there is some lever play in the free position (about 2 mm), but this is due to the structure of the head and does not interfere with performance. *1. A Receptacle and Terminal Box with 1/2-14NPT conduit threads are also available for the North America market. *2. The conduit thread indication has been changed from “PF1/2” to “G1/2” accompanying the JIS B 0202 revision. This changes applies only to the indication; thread sizes and pitches have not been affected. 7 D4A-@N Contact Forms (Switch Boxes) STDP Double-break Switches Contact model Type Without indicator With neon lamp indicator * D4A-0100N D4A-0300N D4A-0E00N Lamp unit Za 4 1 3 4 2 1 Operating pattern With LED indicator * Lamp unit Za 1NC/1NO snap-action 3 4 2 1 Za 3 2 Energized Lamp unit Lamp unit Lamp Unit Internal Circuits Lamp Unit Internal Circuits 1-2 Neon lamp 3-4 LEDs Rectifier stack Resistor Resistor * Switches with indicators are factory-set to light when the switch is not operated.

Furthermore, the lever can be reversed and attached to the shaft (refer to the figures below on the right hand side). Therefore the roller is compatible with a wide movement range of a dog. • A Fork Lever Lock can be used with maintained models (D4A-0005N) only. Remove the head from the Switch by loosening the screws (the screws can be loosened but not removed from the head). The operating head can be positioned and locked in any of four 90° positions. The lever can lock in any position through 360° around the shaft. The lever can be reversed and attached to the shaft, in which case the switching operation should complete in a range of 0° to 180°. 180° operating position 360° operating position Four, M4 x 12 There are four kinds of fork lever locks. The position of each roller is different. It is possible to use D4A-E00 through D4A-E30 levers instead, if they are reversed before attaching. They can be used with D4A-@@05N models only. D4A-E00 D4A-E10 D4A-E20 D4A-E30 By loosening the Allen-head bolt on an adjustable roller lever or rod lever, the length of the lever can be adjusted.

Precautions for Correct Use Operating Environment Lighting Mode Selection of Indicators (SPDT only) • Seal material may deteriorate if a Switch is used outdoor or where subject to special cutting oils, solvents, or chemicals. Always appraise performance under actual application conditions and set suitable maintenance and replacement periods. • Install Switches where they will not be directly subject to cutting chips, dust, or dirt. The Actuator and Switch must also be protected from the accumulation of cutting chips or sludge. Not Suitable The lighting mode of the operation indicator can be changed easily between two modes: lighting when the Switch is operating and lighting when the Switch is not operating. Lights When Not Operating *1 Lights When Operating *2 Suitable Power supply Built-in switch Power supply Internal circuits • Constantly subjecting a Switch to vibration or shock can result in wear, which can lead to contact interference with contacts, operation failure, reduced durability, and other problems. Excessive vibration or shock can lead to false contact operation or damage. Install Switches in locations not subject to shock and vibration and in orientations that will not produce resonance. • The Switches have physical contacts. Using them in environments containing silicon gas will result in the formation of silicon oxide (SiO2) due to arc energy. If silicon oxide accumulates on the contacts, contact interference can occur. If silicon oil, silicon filling agents, silicon cables, or other silicon products are present near the Switch, suppress arcing with contact protective circuits (surge killers) or remove the source of silicon gas. 3 4 4 3 1 2 Load Load 2 1 Built-in switch Internal circuits *1. The lamp is lit when the actuator is at the free position. The lamp will be off when the contacts of the Limit Switch have been actuated and snapped to each other at the operating position. *2. The lamp is lit when the contacts have been released and snapped only from the operating position. Change the lighting mode as follows: 1. Push the claw securing the lamp section to the right (do not push strongly). 2. Remove the lamp section. 3. Mount the lamp section so that legend “NC-ON” or “NO-ON” will appear in the display window. Changing the Operating Direction Roller Lever Switch The head of the side rotary type can be converted in seconds to CW, CCW, or both-way operation. Follow the procedures on the right hand side for conversion (not applicable to the Maintained, Sequential Operating, Center Neutral Operating Switches). Operating Part (Rear of Head) Operating position arrow marks Procedures 1. Dismount the head by loosening the four screws that secure it. 2. Turn over the head to set the desired operation (CW, CCW, or both). The desired side can be selected by setting the mode selector knob shown in the figure. This knob is factory set to the “CW+CCW” (both-way operation) position. 3. When set to the CW position, the head rotates in clockwise direction. When set to the CCW position, the head rotates in counterclockwise direction. In either case, be sure to accurately align the arrow mark to the setting position. In either case, the lamp will not light when the load is ON.

Be sure to tighten each screw to the proper tightening torque as shown in the table. Head (four 12-mm M4 screws): 1.2 to 1.4 N·m Switch box (two 20-mm M5 screws): 2.4 to 2.7 N·m Solderless Terminals The D4A-@N with DPDT double-break incorporates solderless terminals. Operation • The operating methods, cam and dog shapes, operating frequency, and overtravel (OT) have a significant effect on the service life and accuracy of the Limit Switch. The shape of the cam should be as smooth as possible. • A marginal overtravel (OT) value should be set. The ideal value is the rated OT value x 0.7. • The actuator should not be remodeled to change the operating position. Connectors To satisfy IP67, apply sealing tape to the connector conduit. Appropriate external diameter of cables is 5.5 to 14 dia. Use OMRON’s SC-@M Series. Tighten the Connectors to a torque of 1.8 to 2.2 N·m. Maintenance and Repair The user must not maintain or repair equipment incorporating any D4A-N model. Contact the manufacturer of the equipment for any maintenance or repairs required. No. Appropriate tightening torque Type 1 Terminal screws (M3.5 screws) (including grounding terminals) 0.78 to 0.88 N·m 2 3 4* 5 6 Head mounting screws 1.18 to 1.37 N·m Switch box mounting screws 2.35 to 2.75 N·m Body mounting screws 4.90 to 5.88 N·m Connectors 1.77 to 2.16 N·m Actuator mounting screws 2.45 to 2.65 N·m * When using M5 Allen-head bolts, particularly when the head direction has been changed, check the torque of each screw and make sure that the screws are free of foreign substances, and that each screw is tightened to the proper torque.
