One type of sensor used in automation systems, known by most people as the industrial proximity switch within their field of application, is a standardized component. Its non-stop feature is to detect whether there are things nearby or absent without making physical contact with those items at all. Its operation is typically for such things as detection, counting, positioning and safety, this machine, with its state-of the threetechnological features which include noncontact detection, rugged construction and a variety of output configurations, can amply fulfill these main functions. It has been designed to carry out its usual work, which consists of sensing the approach of objects, starting or stopping machines, and making the smooth operation of assembly lines sonorously swift and reliable. In point of fact, the industrial proximity switch is a business protector that raises productivity in relative silence.
