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 pre-
wired. A replaceable fuse for overload protection is easily accessed by
removing the front of the switch with a security bit.

Application Details
Operating Principle
On presenting the actuator to the switch, the high-
intensity 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.
