Description:
Each OPB850A switch has a NPN phototransistor coupled with a 940 nm gallium arsenide infrared emitting diode
in a molded plastic housing. Each OPB850-1Z has a Rbe phototransistor coupled with an 880 nm gallium arsenide
infrared emitting diode in a molded plastic housing. An actuated lever arm flag interrupts the light beam, which
switches the transistor output between states that can readily drive logic gates.
These devices are designed to replace conventional mechanical limit switches where long life and reliability are
critical. The switches are designed to easily snap mount into a 0.036 inch (0.914 mm) 20 gage thick material with
a rectangular opening of 0.315” x 0.472 “ (8.0 mm x 12.0 mm).
Minor differences exist in the package between the OPB850A and OPB850-1Z (see drawings below). The cable
exits the package in different locations.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.

ON (IC(ON)) electrical condition corresponds to the switch point at about 41° angular displacement of the arm.
OFF (IC(OFF)) electrical condition corresponds to the mechanical arm position at rest.
From the rest position to the switch point, lever torque measured at the end of the arm is 1.5 grams maximum.
Wires are 26 AWG, UL rated.
