Description:
The OPB800L series, PCBoard mounting, of wide gap switch provides the flexibility of a custom device from a
standard product line, while the OPB800W series, re mote mounted, switch offers 24” (610 mm) 26 AWG wire
interconnect.
Building from a standard housing that utilizes a 0.375” (9.5 mm) wide slot, a user can specify the electrical output
parameters, discrete shell material and the aperture width.
Housings are made from an opaq ue grade of injection-molded plastic that minimizes the assembly’s sensitivity to
visible and near-infrared ambient radiation. Discrete shells, which are exposed on parallel faces inside the device
throat, are made of IR transmissive plastic (for ap plications whe re aperture contamination may occur) or of opaque
plastic with aperture openings (for maximum protection against a mbient light).
Custom electrical, wire an d cabling and connectors a re available. Contact your local rep re sentative or OPTEK for
more information.
Applications:
• Non-contact interruptive object sensing
• Assembly line automation
• Machine automation
• Equipment security
• Machine safety

Notes:
(1) Derate linearly 1.67 mW/° C above 25° C.
(2) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(3) All parameters tested using pulse technique.
(4) Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and ketones.
(5) The W Series includes wire terminations of 24” (610 mm) 7-strand, 26 AWG UL insulated wire on each terminal. Each device
incorporates a wire strain relief at the housing surface. The insulation functions and colors are: anode (red), cathode (black),
phototransistor collector (white) and phototransistor emitter (green).
