Notes:
(1) For wire series (OPB380, OPB390, OPB880 and OPB890), maximum storage and operating temperature is limited by the
temperature rating of the lead wires.
(2) Derate linearly 1.67 mW/° C above 25° C.
(3) For OPB355, OPB360 and OPB370, polarity is denoted by color of housing top: LED (clear); sensor (black).
(4) Cleaning agents methanol and isopropanol are recommended. Spray or wipe; do not submerge.
(5) OPB380 and OPB390 wire terminations have 24” of 7-strand 26 AWG UL approved insulated wire on each terminal. These
devices incorporate a wire strain relief at the housing surface. The insulation colors and functions are: IRED anode (red); IRED
cathode (black); phototransistor collector (white); phototransistor emitter (green).
(6) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(7) All parameters were tested using pulse technique.
