Slotted switches, also known as optoelectronic slot sensors or optical switches, are used for various applications that require object detection, position sensing, or interruption detection. These devices consist of an emitter and a receiver placed opposite each other, with a gap in between. We offer optical switches with integrated MEMS technology, optical switch kits, and PRO8 modules for fiber-optic circuit integration or construction. Mouser offers inventory, pricing, & datasheets for Transmissive, Slotted Optical Switches. This tutorial explains the operation of the slotted switch and identifies the device's key features and uses.
