Leuze coded magnetic safety system

The coded magnetic safety system is intended for guards and, due to a closed design and the high-strength plastic housing, is suitable for use under critical environmental conditions such as in the pharmaceutical, food and timber industries.

The safety system consists of one MC3x sensor, the corresponding actuator and the MSI-MC310 safety relay. The sensor contains a special combination of reed contacts that are contactlessly activated by the coded magnetic field of the actuator. If, for example, a door is opened, the actuator mounted on the door is separated from the sensor, which is located on the stationary part of the guard and a shutdown signal is triggered. As a result, risky machine movements can only be executed while the guard is closed; and a stop command is executed while the guard is being opened.

For guards that are accessible from behind, a reset button can be connected to the safety relay for manual starting. The system fulfils safety standards up to performance level PLe and safety category 4 in accordance with EN ISO 13849-1.
