These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away. They’re often used to detect when a door or window opens. Mount the switch in a stationary position, such as a door frame, and mount the magnet to a movable object, such as the door. They do not include a safety relay and cannot be used with safety-guard doors found on machinery.

The convenient, modern alternative to mechanical safety switches. These RFID switches are easier to install, fit a wider range of access points, and can mount horizontally. Since they don't need a traditional key to actuate, they work even if the switch and actuator are slightly misaligned. Also known as interlock switches, they shut off power to equipment as soon as you open the barrier, which disconnects the RFID signal. These switches are often used with small machines. Find them anywhere from a CNC machine’s window to a packaging machine’s service panel. Mount the switch on the frame and the actuator on the barrier. Rated IP67 and IP69K, these switches are protected against temporary submersion and high-pressure, high-temperature washdowns.

Block access to machinery while it's running. These safety switches cut power when their signal disconnects, shutting off equipment as you open machine guards. They link to a single actuator, so no other RFID tag or card can interfere. The unique RFID code means that once the power is cut, no one can bypass the switch and restart equipment while the guard is open.

These switches are often used with small machines where there’s no risk of the barrier closing on its own. Find them anywhere from a CNC machine’s window to a machine-operated saw’s service panel. Mount the switch on the frame and the actuator on the barrier. They're also known as interlock switches. Rated IP67 and IP69K, these switches are protected against temporary submersion and high-pressure, high-temperature washdowns.
