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:
The slotted optical sensors in this series provide the flexibility of a custom device from a standard product line.
Building from a standard housing with a 0.125” (3.18mm) wide slot, the user can specify output logic state, output
driver circuit, aperture widt h, aperture surface and mounting tab locations. Furthermore, an option of wire or PCB
leads allows electrical interface flexibility.
The device body is an opaque plastic which minimizes sensitivity to both visible and near-infrared external light
sources which may impact operation. Aperture width choices provide different optical resolution for motion
sensing. A covered aperture provides dust protection, while an open aperture provides maximum protection
against external light sources.
Phototransistor sensor devices are: OPB360, OPB370, OPB380, OPB390, OPB859, OPB860, OPB870, OPB880,
OPB890. The OPB355 provides a photodiode detector, which has a lower linear output-versus-light.
Wide electrical output current ranges are available. LED emissions are near-infrared (850-940nm).
Custom electrical, wire an d cabling services are available.
Contact your local representative or OPTEK for more information. Compliant to EU RoHS Directive 2002/95/EC.

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.
