Square D 9007EA11 Limit Switch Operator Cast Zinc Steel Roller

Product Description

The SQUARE D 9007EA11 is a limit switch operator designed for use with industrial and commercial limit switch assemblies. This rod-style operator measures 3 inches in overall length with a 0.25-inch diameter and features a cast zinc body with a steel roller. The 0.25-inch face width roller actuates the switch mechanism when contacted by a moving machine component. Licensed electricians and industrial maintenance technicians install this operator as part of a complete limit switch setup in machinery, conveyor systems, and automated equipment.

This operator is suited for applications where a compact, durable actuator is needed to interface with a limit switch in an industrial control circuit. It is commonly installed in panel enclosures, machine guarding assemblies, and automated production lines where a moving part must trigger a position or end-of-travel signal. The cast zinc body provides resistance to typical shop-floor conditions.

Key Features

• 3-inch overall length for reach into actuating zones
• 0.25-inch diameter rod-style body for compact fitment
• Cast zinc body construction for durability in industrial environments
• Steel roller contact surface rated for repeated mechanical actuation
• 0.25-inch roller face width for precise trigger contact
• Single-unit packaging with no minimum order quantity above one

Compatibility

Designed as an OEM-style replacement operator for use with SQUARE D limit switches. Confirm mounting interface and actuator style match the target limit switch body before installation.

Installation Notes

Installation should be performed by a qualified electrician or industrial maintenance technician following applicable NEC guidelines. Disconnect and lock out all power to the control circuit before removing or installing the operator. Verify that the operator travel and roller alignment are correct before restoring power. Do not over-torque the mounting fasteners on the cast zinc body, as zinc alloy threads can be damaged by excessive force.
