Eaton / Moeller Series
1NO + 1NC, position switch, roller plunger, snap-action, IP65, IEC/EN 60947
The Eaton Moeller AT4/11-S/IA/RS is a position switch with one normally open (1NO) and one normally closed (1NC) contact configuration. It uses a roller plunger actuator and a snap-action (quick-break) contact mechanism with positive opening operation according to IEC/EN 60947-5-1. Designed for precision detection and industrial safety applications, it ensures reliable switching and secure electrical disconnection. The wide plastic housing offers IP65 protection, and the actuator head can be rotated in 90° intervals for flexible mounting orientations. The device is UL listed, CSA certified, and CE marked, conforming to EN 50041 Form C and global safety and automation standards.
