Mechanical safety switch PSENmech

Secure safety gate monitoring with PSENmech

Mechanical safety switch PSENmech

The mechanical safety switches PSENmech are suitable for safe monitoring of a movable guard. If guards are opened, the safety switches PSENmech are tripped. The hazardous machine movement is then brought to a standstill with the help of the Pilz evaluation device.

Using increased extraction force on the actuator, the PSENmech safety switches prevent the safety gate from being opened unintentionally. They comply with the standard EN ISO 14119 (protection against defeat) due to their mechanically coded actuators.

Certain applications also require the safety gate to be interlocked until the hazardous production process is complete. In this case, a safety gate system with guard locking is the right solution for you.

Get to know the big brother of the safety switch PSENmech: The mechanical safety gate system PSENmech with guard locking also holds the safety gate closed until the production machinery has stopped, while also preventing an unintended restart as long as the gate is open.
