mechanical proximity switch
The proximity switch is a mechanical device used to detect the presence or absence of an object without any physical contact Generated functions include part position detection, counting, and safety guard in industrial automation systems. The mechanical proximity switch is distinguished by an ability to work in rugged and other environments, high precision detection of objects, and easy installation. One sensor and an actuator form this switch pair, working together to give reliable and accurate detection. It is used widely from manufacturing and automotive industries to packaging and robotics for non-contact detection and object sense needs at all levels of performance.
