Overview
The GE CR115E422112 is a geared rotary limit switch engineered for precision control on rotating-drive equipment. This worm and gear-reduction design integrates snap-acting contacts with a Type 4 NEMA enclosure for splash and corrosion protection in demanding industrial environments. The CR115E422112 handles 15 Amperes continuous in AC/DC applications, making it suitable for motor-driven machinery, cranes, hoists, and positioning equipment that require reliable overtravel protection and shaft control.
Key Features
- Type 4 NEMA enclosure for splash protection and corrosion resistance
- 2 normally open (NO) and 2 normally closed (NC) snap-acting contacts
- 15 Amperes continuous rating (AC/DC)
- Worm and gear-reduction mechanism for precise rotation control
- Left-side mounted shaft with standard plain-end configuration
- Durable industrial construction for material handling, overhead doors, and machine tools
