PSENmech mechanical safety switches are suitable for safe monitoring of a movable guard. They are triggered if the guards are opened, and the hazardous machine movement is stopped via a Pilz evaluation device. Using increased extraction force on the actuator, PSENmech safety switches prevent the safety gate from being opened unintentionally. They comply with the standard EN 1088 (protection against defeat) due to their coded actuators. PSENmech safety switches with guard locking ensure that the safety gate is interlocked (guard locking) until the hazardous production process is complete. They can also prevent production from being interrupted as a result of unauthorized access.
