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.
