Square D 9007MA11 Limit Switch Operator Cast Zinc Iron Roller

Product Description

The SQUARE D 9007MA11 is a limit switch operator designed for use with industrial limit switches. It features a cast zinc body measuring 1.5 inches in length and 0.25 inches in diameter, with a 0.25-inch face width and an iron roller. This operator serves as the mechanical actuating element that contacts a moving machine part and transmits that motion to the limit switch mechanism, triggering the switch action. It is installed by electricians and automation technicians working on machine control, conveyor systems, and industrial automation equipment.

The 9007MA11 is suited for industrial control applications where a compact roller-style operator is required on a limit switch assembly. Typical installations include machinery guarding circuits, conveyor end-of-travel detection, and automated positioning systems. The iron roller provides durable contact with cams and actuating surfaces in repetitive-cycle environments. This operator is intended for use with compatible SQUARE D limit switch bodies requiring this operator style and size.

Key Features

• Cast zinc body construction for corrosion resistance in light industrial environments
• Iron roller provides durable surface contact for repetitive actuation cycles
• 1.5-inch overall length fits standard operator mounting configurations
• 0.25-inch diameter and 0.25-inch face width for precise cam engagement
• Compact design suited for tight machine enclosures and mounting spaces

Compatibility

Designed for use with SQUARE D limit switches requiring a roller-style operator. No specific compatible model numbers were provided in the product data. Verify switch body compatibility against the limit switch series documentation before ordering.

Installation Notes

Installation is performed by a licensed electrician or qualified automation technician. De-energize and lock out the machine control circuit before removing or installing any limit switch operator per NFPA 70E lockout/tagout requirements. Inspect the roller and actuating cam for alignment after installation to ensure consistent switch actuation. Do not force the operator beyond its rated travel range or use it as a hard mechanical stop.
