Slotted Optical Switch
OPB200
Description:
The OPB200 contains an Infrared LED (890 nm) and a Phototransistor paired in a plastic housing.
The housing is an opaque grade of injection-molded plastic, which minimizes the assemblys sensitivity to visible
and near-infrared radiation. Each device has approximately 0.060 [1.52 mm] diameter lenses providing the
versatility necessary for general switching applications.
The output Phototransistor ON state conducts current (I
C(ON)
) when no object is in the slot. The output switches to
the OFF state when a device interrupts the light beam from the Emitter (LED) to the Phototransistor. The
Phototransistor can acknowledge light between 400 nm and 1100 nm with optimum response in the 880 nm range.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
