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.

The number of safety outputs, also known as output signal switching devices (OSSDs), tells you how many machines you can control. Each output has a pair of signals that shut down a single machine—if one signal fails, the other takes over as a failsafe.

Switches with a magnetic latch prevent guards from opening by accident, such as from light bumps and low vibrations.

Micro M12 cords (sold separately) connect switches to your system’s circuits.

Trigger a light, alarm, or other device to signal your door is unlocked. These locks have a magnet on the cam that is detected by a sensor (required, sold separately). When you unlock the door, the magnet moves out of the sensing range, activating a switch that turns your device on or off. Lock the door to reset the switch. When choosing a lock, consider the magnet location that works best for your setup. Install your sensor next to the side of the cam where the magnet is located. You cannot use these locks near existing magnetic fields, since they could interfere with the sensor.

These locks open with a slotted screwdriver (not included) for a simple keying system. Also known as quarter-turn locks, they have a cam that rotates 90° to close enclosure doors. You can adjust the cam’s latching distance, so these locks are best for jobs when precise distances are unknown. Adjust the position of the cam before installing.

A gasket stops dust and water from getting into your sealed enclosure through the lock. This helps you maintain the enclosure’s IP65 and NEMA 4 ratings.

Sensors with a light illuminate when the latch is open, so you can see the inside of your enclosure when you swing open the door.

Single pole, double throw (SPDT) sensors can be set to turn a device from off to on (normally open) or from on to off (normally closed).

Open these locks with a square key (sold separately)—it matches a keying system that’s common for industrial enclosures and other machinery but is more secure than a hex key or screwdriver. These locks also have a flat, concealed design that stops others from tampering with them using pliers. Also known as quarter-turn locks, they have a cam that rotates 90° to close enclosure doors.
