Square D 9007C54K Limit Switch Spdt Nc Steel Spring

Product Description

The SQUARE D 9007C54K is a general purpose limit switch designed for industrial position-sensing applications. It features a single-pole double-throw (SPDT) contact form in a normally closed (NC) configuration, actuated by a steel spring mounted at the top of the unit. The metal body is rated IP66 for dust-tight and water-jet protection, making it suitable for demanding environments. Terminal connections are screw-type with a 1/2 inch-14 NPT conduit entry. Licensed electricians and industrial maintenance technicians install this switch as part of machine control, conveyor, or automated equipment circuits.

The 9007C54K is used in residential, commercial, and industrial control systems where reliable position detection is required. Typical applications include conveyor systems, machine tool interlocks, door and gate position sensing, and automated assembly equipment. The switch operates across a wide temperature range of -20 degrees F to 185 degrees F, allowing installation in both cold storage and high-ambient industrial environments. Its NEMA ratings of 1, 2, 4, 6, 6P, 12, and 13 cover a broad range of enclosure and environmental conditions.

Key Features

• SPDT contact form with normally closed (NC) configuration for fail-safe circuit design
• Steel spring actuator mounted at the top for direct mechanical position sensing
• IP66 ingress protection rating — dust-tight and protected against powerful water jets
• NEMA ratings 1, 2, 4, 6, 6P, 12, and 13 for versatile enclosure compatibility
• Screw terminals with 1/2 inch-14 NPT conduit connection for standard electrical installation
• Wide operating temperature range from -20 degrees F to 185 degrees F
• Certified to UL 508, CSA C22.2 No. 14, CE, and RoHS Compliant standards

Compatibility

Designed as an OEM-style replacement or new-installation limit switch for industrial machine control panels and automated equipment requiring SPDT NC spring actuator position sensing with NEMA 4 or 6 environmental ratings.

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 control circuit before mounting or wiring the switch. The 1/2 inch-14 NPT conduit entry accepts standard liquid-tight or rigid conduit fittings. Verify actuator travel and mounting orientation before finalizing the installation to ensure consistent switch actuation without over-travel damage.
