Industrial and consumer applications feature an increasing amount of functionality encompassed in a single device. To provide access to these functions via a user input, there is a growing need for flexibility in the placement of buttons within a confined space. As a result of this increased miniaturization, touchless applications with IR emitter based proximity sensors are becoming even more difficult to design-in due to their wide field of view (FOV). The latest proximity sensors in Vishay’s portfolio are able to overcome these challenges due to their integrated vertical cavity surface emitting laser (VCSEL) with a narrow emission profile VCSEL, and use of the latest package technology optimized to take up as little space as possible on the PCB.
