• Choice of opaque or IR transmissive shell material

• Choice of mounting configurations

• Choice of lead spacing or wires

Description:

The slotted optical sensors in this series provide the flexibility of a custom device from a standard product line.

Building from a standard housing with a 0.125” (3.18mm) wide slot, the user can specify output logic state, output

driver circuit, aperture width, aperture surface and mounting tab locations. Furthermore, an option of wire or PCB

leads allows electrical interface flexibility.

The device body is an opaque plastic which minimizes sensitivity to both visible and near-infrared external light

sources which may impact operation. Aperture width choices provide different optical resolution for motion

sensing. A covered aperture provides dust protection, while an open aperture provides maximum protection

against external light sources.

Phototransistor sensor devices are: OPB360, OPB370, OPB380, OPB390, OPB859, OPB860, OPB870, OPB880,

OPB890. The OPB355 provides a photodiode detector, which has a lower linear output-versus-light.

Wide electrical output current ranges are available. LED emissions are near-infrared (850-940nm).

Custom electrical, wire and cabling services are available.

Contact your local representative or OPTEK for more information. Compliant to EU RoHS Directive 2002/95/EC.

CONTAINS POLYSULFONE

To avoid stress cracking, we suggest using ND Industries’ Vibra-Tite for thread-locking.

ND Vibra-Tite Formula 3 evaporates fast without causing structural failure in OPTEK’s

molded plastics.

Applies to: OPB360, OPB370, OPB380, OPB390

and OPB860, OPB870, OPB880, OPB890.
