Square D 9007MS03S0300 Limit Switch Spdt Nc IP67

Product Description

The SQUARE D 9007MS03S0300 is a general purpose limit switch built for industrial and commercial control applications where reliable position sensing is required. 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 field installation. The unit carries an IP67 ingress protection rating, making it suitable for wet or dusty environments. Operating temperatures range from -40 degrees F to 220 degrees F. Licensed electricians and industrial maintenance technicians are the primary installers of this device.

This limit switch is used in industrial machinery, conveyor systems, automated equipment, and process control panels where mechanical position detection is needed. The top-mounted cross roller plunger actuator is well suited for applications where the actuating cam or dog contacts the switch from a vertical approach. The prewired leads simplify connection in tight enclosures or panel cutouts. It is appropriate for both light industrial and more demanding environments given its NEMA 1, 2, 4, 6, and 6P ratings, covering general-purpose, drip-proof, watertight, and submersible enclosure classes.

Key Features

• SPDT contact form with normally closed (NC) configuration for fail-safe circuit design
• Cross roller plunger actuator located at the top of the switch body for vertical actuation
• IP67-rated metal body withstands temporary submersion and heavy dust ingress
• NEMA 1, 2, 4, 6, and 6P ratings cover a wide range of enclosure and environmental conditions
• Prewired terminals reduce installation time and simplify wiring in confined spaces
• Wide operating temperature range of -40 degrees F to 220 degrees F suits harsh duty cycles
• Meets CE, CSA, UL 508, IEC 60529, and RoHS compliance requirements

Compatibility

Designed as an OEM-style general purpose limit switch replacement for industrial control and machinery applications requiring a top-mounted cross roller plunger actuator in an SPDT NC configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize the circuit and lock out or tag out the equipment before mounting or wiring the switch. Verify actuator alignment with the cam or dog mechanism before final fastening to ensure consistent actuation force and contact reliability. Do not exceed the rated maximum operating force of 80 ounces to avoid premature wear or contact damage.
