The LPC/LMC, CPC/CMC and SPC/SMC series of coded non-contact safety switches offer universal designs, coded magnetic actuation and a NEMA PW12 (IP69K) rating. They are designed to interlock hinged, sliding or removable machine guard doors in factory automation applications and can provide an input to a safety PLC to initiate machine shutdown in an emergency situation. These safety switches are suitable for factory automation when poor guard alignment exists, anti-tamper sensing is required and long life is required (no moving or touching parts).
