Slotted Optical Switch

OPB830 and OPB840 Series (L & W)

Features:

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 housing 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 approved 26 AWG wire leads (W Series).

Housings are made from an opaque grade of injection-molded plastic that minimizes the assembly’s sensitivity to

visible and near-infrared ambient radiation. Discrete shells (exposed on the parallel faces inside the device throat)

are made of either IR transmissive plastic (for applications where aperture contamination may occur) or of opaque

plastic with aperture openings (for maximum protection against ambient light).

Switching of the phototransistor occurs whenever an opaque object passes through the slot and interrupts the

beam.

Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
