Product Bulletin OPB715 June 1998 Photologic Reflective Object Sensor Types OPB715, OPB716, OPB717, OPB718 Features • Focused for maximum sensitivity • 0.5”(12.7mm) sensing distance • Panel mount • Choice of output configurations • 18”minimum wire length Description The OPB715 series reflective assembly consists of a GaAIAs LED and a Photologic sensor enclosed in an IR transmissive housing. The sensor is characterized to detect paper at 0.5” (12.7 mm). However, the OPB715 has a wide operating distance range and is capable of detecting reflective objects at longer distances. Even low reflectance materials can be detected at shorter distances. The sensor’s panel-mount plastic housing shields stray light and is terminated with 18”wire leads. The output can be specified as either TTL totem-pole or TLL open-collector in buffer or inverter polarity. The LED is current limited internally for design convenience. Optek Technology, Inc.
