Features:
0.125” (3.175 mm) slot width
Choice of aperture (0.050” or 0.010” width)
Choice of opaque or IR transmissive shell material
Choice of mounting configurations
Choice of lead spacing or wires
Description:
Each device in this series provides the flexibility of a custom device from a standard product line. Building from a
standard housing with a 0.125” (3.175 mm) wide slot, a user can choose aperture width, opaque or IR
transmissive housing shell material, PCBoard lead spacing or wires and mounting tab configuration.
Housings are made from an opaque grade of injection-molded plastic to minimize sensitivity to both visible and
near-infrared light. Discrete shells exposed on the parallel faces inside each device’s throat are made from either
IR transmissive plastic (for applications where dust protection is needed) or from opaque plastic with aperture
openings (for applications that require maximum protection against ambient light).
Phototransistor sensor devices include the OPB859, PB360, OPB370, OPB380, OPB390, OPB860 and OPB870,
while the OPB355 provides a photodiode sensor. The photodiode sensor has a lower and more linear output-
versus-light input than the phototransistor models.
The OPB355, OPB360, OPB370, OPB859, OPB860 and OPB870 are designed for direct connection to through
hole PCBoards. The OPB380, OPB390, OPB880 and OPB890 have 26 AWG wires connected directly to the
device for remote sensing applications.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.

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 1429 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.
