Non-contact safety switches are interlocking devices that are designed to protect both people and machines. They are preferred in certain applications where no physical contact (under normal conditions) takes place between the switch and actuator.
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.
