Square D 9007MS04S0300 Limit Switch Spdt Nc Rotary

Product Description

The SQUARE D 9007MS04S0300 is a general purpose limit switch designed for industrial and commercial control applications. It features a single-pole double-throw (SPDT) contact form with a normally closed (NC) configuration and a rotary spring return actuator mounted on the side of the metal body. The prewired terminal type simplifies installation and reduces wiring time in the field. Rated IP67 for dust-tight and temporary submersion protection, this switch is built to perform in demanding environments. It 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. Licensed electricians and industrial control technicians are the primary installers of this device.

This limit switch is suited for use in conveyor systems, machine tool controls, door position sensing, and other electromechanical control circuits found in commercial and light industrial facilities. The rotary spring return actuator returns to its home position after contact with a moving object or cam, making it appropriate for applications that require momentary actuation. The side actuator location allows flexible mounting in tight panel or machine enclosures. Its NEMA ratings of 1, 2, 4, 6, and 6P confirm suitability for both indoor and washdown or submersible environments.

Key Features

• SPDT contact form with NC configuration for direct drop-in use in safety interlock and position sensing circuits
• Rotary spring return actuator mounted on the side for compact, flexible installation
• IP67 ingress protection rating — dust-tight and protected against temporary immersion
• NEMA ratings 1, 2, 4, 6, and 6P covering general-purpose through submersible enclosure types
• Wide operating temperature range from -40 degrees F to 220 degrees F
• Prewired terminals for faster field installation
• Metal body construction for durability in industrial environments

Compatibility

Designed as an OEM-style replacement or direct-install general purpose limit switch for industrial and commercial electromechanical control systems requiring SPDT NC rotary actuator switches with side mounting.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize all circuits and lock out or tag out the equipment before mounting or wiring the switch. Verify that the actuator cam or trigger arm travel does not exceed the rated operating force of 48 oz-in to avoid premature contact wear. Confirm enclosure NEMA rating matches the environment before final installation.
