The SIEMENS 3SE7120-2DD01 is a cable-operated metal enclosure switch designed for remote actuation up to 5 m using a Bowden cable. It provides one normally open and one normally closed contact for reliable control and monitoring, mounted through two M20 x 1.5 entries. The unit is non-latching and uses a 55 N return spring with a maximum actuating force of 80 N, giving predictable mechanical response for safety or control circuits. Use it where a compact, cable-driven switching solution is needed and where precise actuation force and simple installation with standard M20 glands are required.
