The MGL Series of safety switches combines magnetic locking and radio-frequency identification (RFID) technology to provide non-contact operation and high anti-tamper coding. In addition, an electromagnet is used to lock machine guards. Heavy-duty or medium-duty holding force models are available in either master coded or uniquely coded actuation configurations. These safety switches are available with plastic, die cast metal or stainless steel housings. The stainless steel housings have an IP69K rating for use in food processing applications. The RFID locking switches use two LEDs to indicate all possible switch states. Two normally-closed safety outputs and one normally-open auxiliary output provide door open indication. MGL series non-contact RFID locking safety switches include both switch and actuator and start at $273.00 .
