Square D 9007MS05S0500 Limit Switch Spdt Nc Cat Whisker

Product Description

The SQUARE D 9007MS05S0500 is a general purpose limit switch designed for industrial position sensing and machine control applications. It features a single-pole double-throw (SPDT) contact form with a normally closed (NC) configuration and a cat whisker actuator style. The switch operates at up to 240 volts AC and is prewired for straightforward field installation. The zinc body construction and IP54 ingress protection rating make it suitable for environments with dust and light liquid splash. Operating temperature range spans -40 degrees F to 220 degrees F, covering demanding indoor and outdoor industrial duty cycles.

This limit switch is used in industrial machinery, conveyor systems, automated equipment, and process control panels where reliable mechanical position detection is required. The cat whisker actuator provides sensitive, multi-directional actuation and is commonly selected for applications involving light contact force against moving parts. NEMA ratings of 1, 12, and 13 confirm suitability for general-purpose, dustproof, and drip-proof indoor enclosures. Qualified electricians and industrial maintenance technicians typically handle installation in accordance with applicable NEC requirements.

• 240 volts AC operating voltage with prewired terminal type for fast field hookup
• IP54 ingress protection rating resists dust and light liquid splash
• NEMA 1, 12, and 13 rated for general-purpose and dustproof indoor applications
• Wide temperature range of -40 degrees F to 220 degrees F for demanding environments
• Meets CE, CSA, UL, RoHS, and multiple IEC standards

Compatibility

Designed as an OEM-style replacement or direct-install general purpose limit switch for industrial machine control and position sensing applications requiring SPDT NC contact configuration with a cat whisker actuator.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC guidelines and all applicable local codes. De-energize and lock out the equipment before mounting or wiring the switch. Verify the actuator path and operating force do not exceed the 15-ounce maximum operating force rating. Secure all prewired leads to prevent chafing or contact with moving components after installation.
