Square D 9007AO2 Limit Switch Spdt Nc Plunger Top Mount

Product Description

The SQUARE D 9007AO2 is a general purpose limit switch designed for industrial control and machine safety 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 is housed in a zinc body and mounts to a panel via screw terminals, making it a straightforward field-replaceable component. Rated for 600 volts AC, it operates across a wide temperature range of -20 degrees F to 185 degrees F. Licensed electricians and industrial control technicians are the typical installers for this type of device.

The 9007AO2 is suited for use in light industrial and commercial control panel environments where machine position sensing or travel limiting is required. The top plunger actuator style is common in conveyor systems, packaging equipment, and other automated machinery where a direct vertical contact trigger is needed. Its IP20 ingress protection rating makes it appropriate for indoor, non-wet locations. Panel mount installation with screw terminal wiring keeps integration with standard control enclosures simple and clean.

Compatibility

Designed as an OEM-style replacement general purpose limit switch for light industrial and commercial control panel applications requiring a top plunger, SPDT, NC configuration with panel mount and screw terminal wiring.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the control circuit before removing or installing the switch. Screw terminal connections should be tightened securely to prevent intermittent contact. The NEMA 1 rating means this switch must be installed in a dry, indoor location only — do not expose it to moisture, oils, or coolants.
