Namco ET130-22420 Electronic Inductive Proximity Switch

Namco ET130-22420 is an electronic inductive proximity switch designed for non-contact detection of metallic targets in industrial automation. It operates from an 80–250 VAC supply and draws 200 mA, making it compatible with many standard AC control circuits and power sources in control panels. When a metal object comes within sensing range, the switch changes state to provide a digital input to a controller or relay, enabling machine logic to respond without the wear and tear of mechanical switches. The ET130-22420's solid-state sensing makes it suitable for use in equipment where metal presence or position must be detected and fed into automation sequences, such as machinery interlocks, part presence sensing, or process monitoring in manufacturing environments where reliability is critical and wiring follows common AC control conventions.
