Description:
The OPB735 series sensors consist of an infrared light emiꢂng diode and an NPN silicon phototransistor or photodarlington,
encased side-by-side on converging opꢀcal axes in a black thermoplasꢀc housing.
The detector responds to light from the IRED only when a reflecꢀve object passes within its field of view.
The OPB735 series employs hermeꢀcally sealed metal can packaged components.
The OPB735X series has 4 leads . The OPB735XWZ series has interconnect wires at 12” (300 mm) length UL 1569 approved
#28 AWG, stripped and ꢀnned.
Custom electrical, wire, cabling and connectors are available. Contact your local TT Electronics—OPTEK representaꢀve for
