Description:
The OPB960/ 970/ 980/ 990 series of non-contact Photologic
®
slotted optical switches provides flexibility in meeting application
specific requirements for the design engineer.
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.
Electrical operation is over a wide supply voltage range. LED emissions are near-infrared (850—940nm).
Detector digital output logic choices of buffer or inverter with totem-pole or open-collector driver circuit simplify interface for
various electrical requirements.
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 .
