OPB990T55Z
Product Description
Product Overview
The OPB960/970/980/990 series of non-contact Photologic slotted optical switches offer design engineers flexibility through customizable output logic, driver circuits, aperture widths, and mounting options. With a standard 0.125" (3.18mm) slot, these devices are built to minimize sensitivity to external light sources and provide different optical resolutions for motion sensing. They are suitable for a wide range of applications including speed and direction indication, rotary encoders, and mechanical switch replacement.
