Square D 9007AP221 Limit Switch Spdt Nc Plunger

Product Description

The SQUARE D 9007AP221 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 top-mounted plunger actuator. The switch mounts via panel with screw terminals for straightforward field wiring. Built with a zinc body, it delivers durable performance across a wide operating temperature range of -20 degrees F to 185 degrees F. Maximum operating force is 0.88 pounds, making it suitable for light to moderate actuation loads. Licensed electricians and industrial control technicians are the primary installers of this device.

The 9007AP221 is suited for use in machinery, conveyor systems, and other automated equipment where precise position sensing or end-of-travel detection is required. Its top plunger actuator style allows direct mechanical contact with moving components. The panel mount configuration supports installation in control enclosures or directly on machine frames. With an IP20 ingress protection rating and NEMA 1 rating, this switch is intended for indoor, non-hazardous dry environments typical of light industrial and commercial settings.

Compatibility

Designed as an OEM-style replacement general purpose limit switch for industrial control and automation applications requiring a panel-mount, top-plunger SPDT NC switch rated at 600 volts AC.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all power to the circuit before wiring or replacing this switch. Secure the switch firmly to the panel mount surface before making screw terminal connections, and verify actuator alignment with the mechanical trigger to ensure consistent switching action.
