AC (Ue) (le) DC Thermal Current (lth) Description A heavy-duty hinge actuated safety interlock switch, the Rotacam shaft can be used as, or connected to, the existing hinge pin for direct operation of the switch. Machine power is isolated when the guard has been opened just 5°. For applications requiring a larger degree of operation the internal cam can be adjusted from 5° to 11°. Note: After adjustment, the cam must be secured in position with the Minimum Current Safety Contact Gap Rtd. Insulation Voltage Rtd. Impulse withstand Voltage Shaft Rotation to Achieve Contact Operation Break Contact Min Force Max Actuation Speed Max Actuation Frequency Case Material Actuator Shaft Protection Conduit Entry Operating Temperature Fixing Mounting Mechanical Life Electrical Life Weight Colour supplied cam locking pin to ensure optimal performance. The Rotacam is available with two N.C. safety contacts and one N.O. auxiliary contact. The switch includes the necessary safety related functions, such as forced guided contacts and a tamper resistant mechanism, allowing machinery to be safeguarded in compliance with the machinery directive. The die-cast housing is sealed to IP66 and features one M20 conduit entry (1/2in NPT and connector style also available). Two different shaft lengths of 30mm and 85mm can also be specified. EX and Pneumatic styles of Rotacam are also available; see the Explosion Proof section on page 16-1 for more information. Features • Can be used as a hinge pin on light and medium weight guard doors • Isolates power within 5° of door movement • Degree of operation can be customized with adjustable cam • Robust die-cast case, ideal for heavy duty applications • Contacts, 2 N.C. & 1 N.O. Note: The safety contacts of the Guardmaster switches are described as normally closed (N.C.) i.e., with the guard closed, actuator in place (where relevant) and the machine able to be started. Fixing Methods Roll Pin Pre-Bored The actuator shaft is pre-bored allowing the existing hinge pin to be utilised as the flexing point. Solid Shaft The solid actuator shaft can be used as the hinge pin on certain guards. 3-76 Interlock Switches Hinge Switches Rotacam Product Selection Type Size (L=Length: D-Dia) mm (inches) L = 30 (1.18) D= 16 (0.63) L = 85 (3.35) D= 12.7 (0.5) Catalogue Number Shaft Type Pre-Bored Solid M20 Conduit 440H-R03074 440H-R03079 M20 Conduit/ 1/2in Adaptor 440H-R03078 440H-R03088 Quick Disconnect 440H-R03111 440H-R03112 Safety Contacts Auxiliary Contacts BBM/MBB 2 N.C. 1 N.C.
