Square D 9007MS01S0500 Limit Switch Spdt Nc Plunger

Product Description

The SQUARE D 9007MS01S0500 is a general purpose limit switch designed for industrial and commercial machine control applications. It features a top-mounted plunger actuator with a single-pole double-throw (SPDT), normally closed (NC) contact configuration and arrives prewired for faster installation. The zinc die-cast body carries an IP67 ingress protection rating, making it suitable for wet and dusty environments. Rated for 240 volts AC with a maximum operating force of 80 ounces, this switch is built to handle demanding duty cycles where reliable position sensing is required. Licensed electricians and industrial control technicians are the primary installers.

This limit switch is suited for use in manufacturing, material handling, conveyor systems, and automated machinery where precise actuator position detection is needed. The top-entry plunger actuator responds to direct linear contact from a machine component or cam, triggering the SPDT output to signal a controller or safety circuit. Its wide operating temperature range of -40 degrees F to 220 degrees F makes it viable in cold storage, foundry-adjacent, and outdoor-rated enclosure applications. NEMA ratings of 1, 2, 4, 6, and 6P confirm suitability across a broad range of enclosure environments.

Key Features

• SPDT normally closed contact configuration for fail-safe position sensing
• Top-mounted plunger actuator with 80 ounce maximum operating force
• IP67-rated zinc body resists water immersion and particulate ingress
• Prewired terminal connection simplifies field installation
• NEMA ratings 1, 2, 4, 6, and 6P for versatile enclosure compatibility
• Operating range from -40 degrees F to 220 degrees F for extreme environment use

Compatibility

Designed as an OEM-style replacement or new-installation general purpose limit switch for industrial control panels and automated machinery requiring a top-plunger SPDT configuration rated at 240 volts AC.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the machine control circuit before mounting or wiring the switch. Verify actuator alignment and travel distance against the plunger stroke specification before finalizing the mounting position. Do not exceed the rated operating force or operating temperature limits stated for this device.
