Description

The OPB380/390 series of slotted

switches provides the design engineer

with the flexibility of a custom device

from a standard product line. Building

from a standard housing with a 0.125"

(3.18 mm) wide slot, the user can specify

(1) electrical output parameters, (2)

mounting tab configuration, (3) discrete

shell material, and (4) aperture width.

All housings are an opaque grade of

injection-molded plastic to minimize the

assembly's sensitivity to ambient

radiation, both visible and near-infrared.

Discrete shells (exposed only on the

parallel faces inside the device throat)

are either IR transmissive plastic for

applications where aperture

contamination may occur or opaque

plastic with aperture openings for

maximum protection against ambient

light.

(2) All parameters tested using pulse technique.

(3) The OPB380/OPB390 wire terminations are 24" of 7 strand, 26 AWG, UL 1429 insulated wire

on each terminal. The devices incorporate a wire strain relief at the housing surface. The

insulation colors and functions are:

RED - IRED Anode

WHITE - Phototransistor Collector

BLACK - IRED Cathode

GREEN - Phototransistor Emitter

Other wire lengths and/or colors are available. Contact your local representative or call the

factory.
