OPB720

Long Distance Reflective Switch OPTEK Technology OPB720 • • • • • Detection distance from 0.04” (1 mm) to 24” (610 mm) [maximum distance to be set at the factory] Ambient Light Rejection < 100K Lux Object size as small as 0.08” (2mm) can be recognized Cable Length and Termination options Open collector output Product Photo Here The OPB720 is a reflective switch designed to detect objects as far away as 24” (610 mm). Detectable object sizes can be as small as 0.08” (2mm) at a distance of 8” (20 mm). The OPB720 has a logical output that switches from a high level with no reflection target to a low level with a reflection target. With the addition of hysteresis, the OPB720 minimizes switching oscillations on the output. The open collector output transistor and power requirements is compatible with most PLC’s Applications include: • Conveyer belt package recognition • Personnel movement recognition • Near focus security systems • Hand wash and soap dispensing stations • Toilet and urinal sensors • Product dispensing systems e r P im l a in y r Vcc Electronics Ground Output Color Description Red White Black Vcc Output Ground Dimensions are in inches [ millimeters] Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
