OFS

Product Data

The OFS series consists of self-contained optical fork sensors that are housed in a durable, U-shaped aluminium housing which operates in thru-beam mode, available with infrared (OFS), visible red light (OFSR) or high power infrared (OFSH). The series is available with a wide variety of fork opening widths, ranging from 10 mm to 220 mm.

The complete series is available as a 3 wire, NPN or PNP transistor output with a 10-35 V dc supply voltage. All models offer sensitivity adjustment via integral potentiometer and are available with switch selectable light or dark function. The complete series offers a high switching frequency of up to 5000 Hz.

The series is protected against reverse polarity of power supplies and output signals. The output is protected against short circuit and inductive loads.
All products include a 3-year worldwide warranty.
