IFM Electronics OGE500 through-beam receiver sensor is made of 316L/1.4404 stainless steel, PA, LCP, EPDM, TPU housing, PMMA lens. It features DC PNP electrical design, 10 to 36V DC operating voltage, 11mA current consumption. It features DC PNP electrical design, 10 to 30V DC operating voltage, <12mA current consumption. The transmitter emits a fine laser beam which is received by the receiver. The interruption of the laser beam is evaluated. The small beam diameter allows detection of tiny objects and their exact positioning.
