Square D 9007MS02S0400 Limit Switch Spdt Nc Roller Plunger

Product Description

The SQUARE D 9007MS02S0400 is a general purpose limit switch built for industrial and commercial control applications where reliable position sensing is required. The unit features a side-mounted roller plunger actuator and a single-pole double-throw (SPDT) contact form with a normally closed (NC) configuration. It operates at up to 240 volts AC and ships prewired for straightforward installation. The zinc die-cast body carries an IP67 ingress protection rating, making it suitable for wet and dusty environments. Licensed electricians and industrial controls technicians are the primary installers of this device.

This limit switch is used in conveyor systems, machine tool controls, automated assembly lines, and other industrial automation setups where a mechanical actuator must signal a control circuit. The side-entry roller plunger responds to linear or rotary cam motion and triggers the SPDT output to open or close a circuit. It handles an operating temperature range of -40 degrees F to 220 degrees F, covering both cold storage and high-heat industrial environments. The prewired terminal style reduces field wiring time in panel and machine-mount installations.

Key Features

• SPDT contact form with normally closed (NC) configuration for fail-safe circuit design
• Side-mounted roller plunger actuator for cam or linear actuation
• IP67 ingress protection rating — dust-tight and submersion-resistant
• NEMA ratings 1, 2, 4, 6, and 6P for broad environmental suitability
• Prewired terminal type for reduced field wiring time
• Zinc body construction for durability in industrial settings
• Wide temperature range: -40 degrees F to 220 degrees F

Compatibility

Designed as an OEM-style replacement or direct-fit general purpose limit switch for industrial control panels and automated machinery requiring a side-actuated SPDT roller plunger switch at 240 volts AC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and the equipment manufacturer guidelines. Disconnect and lock out all power to the control circuit before removing the existing switch or making new wiring connections. Verify the actuator travel and cam geometry align with the roller plunger travel path before final mounting. Do not exceed the rated maximum operating force of 80 ounces to avoid premature actuator wear.
