Square D 9007C52A2 Limit Switch Spdt Nc Rotary Head

Product Description

The SQUARE D 9007C52A2 is a general purpose limit switch designed for industrial and commercial control applications. It features a rotary head actuator mounted on the side of the metal body, a single-pole double-throw (SPDT) contact form in a normally closed (NC) configuration, and side screw terminals for secure wiring connections. The unit connects via a 1/2 inch-14 NPT conduit entry and carries an IP66 ingress protection rating, making it suitable for environments exposed to dust, debris, and water spray. Electricians and automation technicians install this switch as a position-sensing or end-of-travel detection device in machine control circuits.

This limit switch is well suited for use in industrial machinery, conveyor systems, door and gate controls, and process equipment where reliable position detection is required. Its operating temperature range of -20 degrees F to 185 degrees F supports both indoor and outdoor installations in moderate industrial environments. The metal body construction and multi-NEMA-rated enclosure make it a practical choice for demanding plant floor and OEM panel applications.

Key Features

• SPDT contact form with normally closed (NC) configuration for reliable position sensing
• Rotary head actuator with side-mount orientation for flexible installation layouts
• IP66 ingress protection rating resists dust and high-pressure water
• NEMA ratings 1, 2, 4, 6, 6P, 12, and 13 cover a wide range of enclosure environments
• 1/2 inch-14 NPT conduit connection with side screw terminals for secure field wiring
• Wide operating temperature range: -20 degrees F to 185 degrees F

Compatibility

Designed as an OEM-style replacement or new-installation general purpose limit switch for industrial machine control panels and equipment requiring SPDT rotary-head position sensing with NPT conduit entry.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the machine control circuit before mounting or wiring the switch. Use conduit fittings rated for the installed environment and torque screw terminals to the value specified on the switch or enclosure documentation. Verify actuator rotation direction and travel limits before returning the machine to service.
