Overview
The Square D 9007C52D is a heavy-duty compact limit switch designed for demanding industrial automation and control applications. This SPDT (single-pole, double-throw) configuration provides 1NO/1NC contacts with snap-action operation for positive switching in machine tool, conveyor, and material handling systems. The switch is manufactured by Schneider Electric and carries UL, CSA, and CE certifications.
Key Features
- Top Roller Plunger Actuator: Smooth rolling contact reduces mechanical wear and extends service life.
- Snap-Action Contacts: Momentary spring return operation with positive circuit transition.
- NEMA-Rated Enclosure: Meets NEMA 1/2/4/6/6P/12/13 standards for diverse mounting environments.
- IP67 Protection: Sealed against dust and temporary water immersion, suitable for washdown areas.
- Silver Alloy Contacts: Enhanced electrical conductivity and corrosion resistance.
- Compact Design: Space-efficient form factor for tight panel and equipment installations.
