The Euchner N01R572-M is a single limit switch fitted with a roller plunger actuating element (roller diameter 5 mm), operated by an actuating force of 15 to 20 N at approach speeds between 0.01 and 50 m/min. It provides one changeover contact with snap-action switching, connected via an M12 x 1.5 connector, and is rated IP67 with a die-cast alloy housing suited to mounting in any orientation. Contacts are silver alloy with gold flashing, giving reliable operation at low switching currents such as 10 mA at DC 12 V, making the switch suitable for position and door monitoring applications on industrial machinery and safety-related control panels.
