Operating on 12 to 24 VDC, it features a PNP open collector output rated at 100 mA or less and utilizes a red 4-element LED light source for reliable fiber optic detection. Connection is made via an M8 connector, providing a compact and secure interface in space-constrained installations.

This unit is the main unit configuration with a single PNP control output and an external input with a 2 ms ON response time. The power boost function allows the sensor to be switched to its highest sensitivity setting via an on-board dip switch.
