The position switches are designed for continuous use in safety circuits / safety functions as part of functional safety of machines up to SIL 2 (IEC 61508) or PL d (ISO 13849).
HLS 100 consists of two parts, the encoder magnet and the sensor unit. Using two Hall sensors in the sensor unit, it detects the defined position (limit position) of the magnet and sends the switching condition "ON" if this position is detected, and otherwise the switching condition "OFF". Switching conditions are output as permanent PWM signals. During stable normal operation, the position switch cyclically performs internal diagnosis steps, which identify systematic and random errors.
Errors which occur are therefore detected directly. The output signal is then deactivated completely and the sensor is restarted.
