Square D 9007MS02S0102 Limit Switch Spdt Nc Roller Plunger

Product Description

The SQUARE D 9007MS02S0102 is a general-purpose limit switch designed for industrial position-sensing and machine-control applications. It uses a side-mounted roller plunger actuator and a single-pole double-throw (SPDT) contact form with a normally closed (NC) configuration. Rated at 240 volts AC and carrying an IP67 ingress protection rating, this switch handles wet, dusty, and high-vibration environments. The zinc body provides mechanical durability, and the prewired terminal design simplifies field installation. Licensed electricians and industrial maintenance technicians typically specify this switch for conveyor systems, door interlocks, and automated machinery.

This limit switch suits residential, commercial, and light industrial control circuits where reliable position detection is required. The side-actuator orientation allows mounting in tight enclosures or along machine frames where a top-actuated switch cannot fit. The prewired leads eliminate the need for field wiring terminations at the switch body, reducing installation time on new equipment builds and replacement jobs alike. The operating temperature range of -40 degrees F to 220 degrees F makes it viable for outdoor installations and process environments with elevated ambient heat.

Key Features

• SPDT contact form with NC configuration for fail-safe position sensing
• Side-mounted roller plunger actuator for space-constrained mounting orientations
• IP67-rated zinc body resists water immersion, dust, and mechanical impact
• Prewired terminals for faster field installation without on-body wiring
• NEMA 1, 2, 4, 6, and 6P enclosure ratings for broad environmental compatibility
• Wide temperature range: -40 degrees F to 220 degrees F

Compatibility

Designed as an OEM-style replacement for general-purpose industrial limit switches requiring a side roller plunger actuator, SPDT NC contacts, and prewired leads in a compact zinc-body housing.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and the equipment manufacturer guidelines. De-energize and lock out the circuit before removing the existing switch or making any wiring connections. Verify actuator alignment and travel distance against the machine manufacturer specifications before torquing mounting hardware. Confirm the operating force does not exceed the rated maximum of 80 ounces to prevent premature actuator wear.
