OPB718传感器变送器的光学传感器-光电工业规格书PDF中文资料

描述 Description

The OPB715 series reflective assembly consists of a GaAIAs LED and a Photologicâ 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.
