The IN4000 non-contact safety switch is an inductive safety switch that is activated by metal (e.g. steel ST37). It does not, therefore, require a separate coded actuator.
Due to the non-contact form of operation, this sensor has advantages in that it is straightforward to adjust and install. It also has increased resistance to shock and vibration.
The response range of the sensor is monitored spatially and over time. In this way, increased protection against tampering is provided.
