The OPB715Z series reflective assembly consists of a GaALAs LED and a Photologic sensor enclosed in an IR transmissive housing. The sensor is characterized to detect paper at 0.5" (12.7 mm). The sensor has a wide operating distance range and is capable of detecting reflective objects at other distances. The reflective distance depends on the reflectance materials. The sensor's panel-mount plastic housing shields stray light and is terminated with 18" (457 mm) UL approved 26 AWG wire leads. The LED is current limited internally for design convenience. Its output can be specified as either TTL Totem-Pole or TLL Open-Collector. Inverted output options are available for either output configuration.
