Product Overview
The OPB700Z, OPB700ALZ, OPB701Z, and OPB701ALZ are reflective object sensors featuring an infrared emitting diode and either a NPN silicon phototransistor (OPB700 series) or a NPN silicon photodarlington (OPB701 series). These sensors are housed in a black plastic enclosure with converging optical axes. They are designed for non-contact object detection in applications such as assembly line automation, machine automation, machine safety, end-of-travel sensing, and door sensing. The devices are available with UL approved #26 AWG Teflon insulated wire in 4" (101 mm) or 18" (457 mm) lengths, with custom options also available.
