IN4000

Data Sheet IN 4000 Safety Sensor The safety sensor IN 4000 is an inductive safety sensor 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 sensor is BIA-approved and is certified for cat. 4 in accordance with EN 954-1. The sensor can be connected directly to a safe PLC or to the IN 4000 relay evaluation unit. Due to the detection of short circuits and crossed circuits, several sensors can be connected in series. The response range of the sensor is monitored spatially and over time. In this way increased protection against tampering is provided. The input and output signals on the sensor correspond to EN 61131-2 and are thus compatible with the I/O signals on the safe PLC. Using LEDs the status indication can be read directly on the sensor or the protective device. Failures, for example a coil break, short circuit or cable break are detected by the sensor's self-monitoring. Up to 10 sensors can be connected to the IN 4000 relay evaluation unit. External device monitoring, 3 safetyrelevant normally open contacts and 2 normally closed diagnostic contacts provide a high degree of flexibility for the integration in the controller.
