Interlock Switches Non contact Switches Sentinel 1 Specifications Standards EN954-1, ISO13849-1, IEC/EN60204-1, NFPA79, EN1088, ISO14119, IEC60947-5-1, ANSI B11.19, AS4024.1 Category Cat. 3 per EN954-1 Approvals CE marked for all applicable directives Power Supply 24V AC/DC, 48V AC, 110V AC, 230V AC Power Consumption < 2VA Internal Fuses Power 250mA replaceable N.C. Output 2A replaceable Description The Sentinel 1 is an electro-magnetically coded standalone Non contact interlock. It operates without a safety relay while providing a highly coded system to help prevent defeat of the switch by simple magnets. Self-checking and monitoring functions are contained in the switching unit which also has LED status indication. The Sentinel 1 has 1 N.O. and 1 N.C. output and is supplied prewired. A replaceable fuse for overload protection is easily accessed by removing the front of the switch with a security bit.

Fuse Externally Black White Yellow Auxiliary N.O. Green Application Details Operating Principle On presenting the actuator to the switch, the highintensity electromagnetic field together with a resonant frequency signal causes the contacts to close. On removing the actuator, (opening the door) the safety contacts open, isolating the machine. The switch can not be overridden by magnets, tools, etc. Actuator Approaches ✔ ✔ ✔ 3-66 Interlock Switches Non contact Switches Sentinel 1 Application Details—Installation Mounting Hinge Guards Door stop Double Hinge Guards Switch ≤25mm Switch 2mm Minimum 5mm Maximum Switch Actuator Actuator Guard Actuator Sliding Guards Lift Off Guards 2mm Minimum 5mm Maximum Switch 2mm Minimum 5mm Maximum Switch Actuator Switch Guard Actuator Guard Actuator Door stop 3-67
