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 Cat. 3 per EN954-1 CE marked for all applicable directives 24V AC/DC, 48V AC, 110V AC, 230V AC < 2VA Category Approvals Power Supply Power Consumption Internal Fuses Power 250mA replaceable N.C. Output 2A replaceable Operating Distance Make 7mm (0.28in) Break 10mm (0.39in) 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 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 Switch Switch 2mm Minimum 5mm Maximum Guard Actuator Actuator ≤25mm Switch Actuator Door stop Double Hinge Guards Lift Off Guards Sliding Guards 2mm Minimum 5mm Maximum 2mm Minimum 5mm Maximum Switch Actuator Switch Switch Guard Actuator Guard Actuator Door stop 3-67
