The NM12AK-M is a safety switch from Euchner's NM series, using a hinged actuator and a long housing format. It is designed to detect the position of guards and doors on machinery, forming part of a safety interlocking circuit. Typical applications include hinged guard doors on industrial machines and panels where the housing length suits the mounting arrangement.
