HLS 100 Position Switches for applications with increased functional safety

The position switch series HLS 100 has been specifically developed to detect the end position of safety related devices on mobile machinery.

The position switches are designed for continuous use in safety circuits/ safety functions as part of the functional safety of machines up to SIL 2 (IEC 61508) or PL d (ISO 13849).

The HLS 100 consists of two parts, the encoder magnet and the sensor unit.

Using two Hall sensors integrated into the sensor unit, the sensor detects the defined position (end position) of the magnet and transmits the switching condition "ON" if this position is detected, or otherwise the switching condition "OFF".

Switching conditions are output as permanent PWM signals. During stable normal operation, the position switch cyclically performs internal diagnostic steps, which identify systematic and random errors.

Errors which occur are therefore detected immediately. The output signal is then deactivated completely and the sensor is restarted.

Special features:

• Compact design
• Robust housing suitable for mobile applications
• High operating temperature range
• PWM output
• IP 67 male connector
• SIL 2 / PL d certification
