The OG Basic Line of photoelectric sensors have extended sensing ranges of 20 m for thru-beam, 4 m for polarized retroreflective, and 250 mm for diffuse background suppression with potentiometer setup for precise applications.
The sensors can be placed farther from the target, which provides protection against mechanical damage. The sensor's threaded housing is made of 316 stainless steel with an integrated PMMA lens. The device uses a standard M12 cable assembly for electrical connection. The sensors are three-wire dc, pnp units available in dark-on or light-on modes.
