Eaton / Moeller Series
1NO + 1NC, position switch, angled roller lever, snap-action, IP65, IEC
The Eaton Moeller ATR-11-S-IA/ARK is a position switch with one normally open (1NO) and one normally closed (1NC) contact, featuring an angled roller lever actuator. It uses a snap-action (quick-break) contact mechanism that ensures fast and precise switching. The switch is designed with a positive-opening safety function per IEC/EN 60947-5-1, making it suitable for use in safety circuits. Built with a durable insulated plastic housing, the device offers IP65 protection and is engineered for industrial automation and control applications. The actuator can be rotated in 90° intervals to match the required approach direction, providing versatility and reliability in harsh environments.
