Square D 9007MS03S0100 Limit Switch Spdt Nc Cross Roller

Product Description

The SQUARE D 9007MS03S0100 is a general purpose limit switch designed for industrial position sensing and machine control applications. It features a cross roller plunger actuator mounted at the top of the metal body, a single-pole double-throw (SPDT) contact form with a normally closed (NC) configuration, and a prewired terminal connection for straightforward installation. Rated IP67 for dust-tight and temporary submersion protection, this switch holds up in wet, dirty, or wash-down environments. The unit operates across a wide temperature range of -40 degrees F to 220 degrees F, making it suitable for both cold-storage and high-heat industrial settings. It weighs 0.65 pounds.

This limit switch is used in industrial and commercial machine tool, conveyor, and automated equipment applications where precise position or end-of-travel detection is required. The top-mounted cross roller plunger actuator suits installations where the actuating force approaches from directly above or along the plunger axis. A licensed electrician or qualified industrial maintenance technician typically handles installation. The prewired terminals speed up field wiring in panel, enclosure, or direct-mount configurations. NEMA ratings of 1, 2, 4, 6, and 6P cover general indoor, drip-proof, watertight, and submersion-resistant environments.

Key Features

• SPDT contact form with normally closed (NC) configuration for fail-safe position detection
• Cross roller plunger actuator, top-mounted, rated to 80 ounces maximum operating force
• IP67 ingress protection rating — dust-tight and protected against temporary submersion
• Metal body construction for durability in industrial environments
• Wide operating temperature range: -40 degrees F to 220 degrees F
• Prewired terminals for faster field installation
• NEMA ratings 1, 2, 4, 6, and 6P

Compatibility

Designed as an OEM-style general purpose limit switch for industrial machine control, conveyor systems, and automated equipment requiring SPDT NC top-actuated position sensing with NEMA 4 or NEMA 6 rated enclosures.

Installation Notes

Installation should be performed by a licensed electrician or qualified industrial maintenance technician in accordance with NEC requirements and the equipment manufacturer's wiring diagrams. Disconnect and lock out all power sources before removing the existing switch or making wiring connections. Verify actuator alignment and approach angle before final mounting to ensure consistent actuation force does not exceed the 80-ounce rated maximum. Confirm the mounting surface and enclosure rating are compatible with the application's ingress protection requirements.
