Square D 9007MS02S0300 Limit Switch Spdt Nc Roller Plunger

Product Description

The SQUARE D 9007MS02S0300 is a general purpose limit switch configured as SPDT with a normally closed contact form and a parallel roller plunger actuator mounted at the top of the unit. Built with a metal body, it is designed for industrial and commercial control circuits where precise mechanical position sensing is required. The switch arrives prewired for straightforward field termination. It carries an IP67 ingress protection rating, making it suitable for wet and washdown environments, and meets NEMA ratings 1, 2, 4, 6, and 6P. Operating temperature range extends down to -40 degrees F, supporting cold-storage and outdoor installations.

This limit switch is used in industrial machinery, conveyor systems, door and gate position sensing, and similar electromechanical control applications where a moving mechanical component must trigger a circuit change. The top-mounted parallel roller plunger style is a common configuration for actuating against cams or moving machine members in a straight-line approach. It is typically installed by licensed electricians or qualified industrial maintenance technicians working on low-voltage machine control circuits.

Key Features

• SPDT contact form with normally closed configuration for fail-safe circuit design
• Parallel roller plunger actuator, top-mounted, for straight-line mechanical actuation
• IP67 ingress protection rating — dust-tight and submersion-resistant
• NEMA ratings 1, 2, 4, 6, and 6P for broad environmental suitability
• Metal body construction for durability in industrial environments
• Prewired termination reduces field wiring time
• Rated to a minimum operating temperature of -40 degrees F

Compatibility

Designed as an OEM-style replacement or new-installation limit switch for general purpose industrial machine control applications requiring a top-mount parallel roller plunger SPDT configuration.

Installation Notes

Installation should be performed by a licensed electrician or qualified industrial maintenance technician in accordance with NFPA 70 (NEC) and applicable machine safety standards. De-energize and lock out the equipment per LOTO procedures before mounting or wiring the switch. Verify actuator alignment with the cam or actuating surface before securing the switch body to avoid premature wear or missed actuation. Do not exceed the rated maximum operating force of 80 ounces to prevent mechanical damage to the actuator.
