Slotted Optical Switch
OPB830 and OPB840 Series (L & W)
Features:
• 0.125” (3.18 mm) wide slot
• Choice of electrical output parameters
• Choice of aperture
• Choice of opaque or IR transmissive shell material
• Side mount configuration
• Choice of lead spacing (L Series)
• 24” [610 mm] 26 AWG wire leads (W Series)
Description:
OPB830 and OPB840 series provide the design engineer with the flexibility of a custom device from a standard
product line. The L Series offers a choice of PCBoard mount lead spacing, while the W Series offers
24” (610mm) 26AWG wire leads.
Building from a standard housin g that utilizes a .375” (9.5 mm) wide slot, a user can specify the electrical output
parameters, choice of aperture, discrete shell material, side mount configuration, and a choice of lead spacing (for
the L Series) or 24” [610 mm] UL app roved 26 AWG wire leads (W Series).
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 (exposed on the pa rallel faces inside the device throat)
are made of either IR transmissive plastic (for ap plications where aperture contamination may occur) or of opaque
plastic with aperture openings (for maximum protection against a mbient light).
Switching of the phototransistor occurs wheneve r an opaque object passes through the slot and interrupts th e
beam.
Custom electrical, wire an d cabling and connectors a re available. Contact your local rep re sentative or OPTEK for
