Square D 9007MA18 Limit Switch Operator Cast Zinc

Product Description

The SQUARE D 9007MA18 is a limit switch operator designed for use with industrial limit switches in control and automation applications. This roller-style operator features a cast zinc body measuring 1.5 inches in overall length and 0.75 inches in diameter, with a 0.25 inch face width nylon roller. The cast zinc construction provides durability in demanding service environments, while the nylon roller allows smooth, low-friction actuation. Electricians and automation technicians install this operator as part of a limit switch assembly to detect machine position, end-of-travel, or object presence in industrial control circuits.

The 9007MA18 is suited for use in light industrial and commercial control panel installations where a compact roller operator is required. It is typically installed on machinery, conveyor systems, and automated equipment where reliable mechanical actuation of a limit switch is needed. This operator is designed to mate with compatible SQUARE D limit switch bodies as a serviceable component, allowing field replacement of worn or damaged operators without replacing the entire switch assembly.

Compatibility

Designed for use with SQUARE D limit switches. Consult the limit switch documentation to confirm this operator is compatible with the specific switch body being serviced before installation.

Installation Notes

Installation is typically performed by a qualified electrician or industrial maintenance technician. De-energize and lock out the control circuit before removing or installing any limit switch component, following OSHA lockout/tagout procedures. Verify the operator threads or mounts securely to the limit switch body and that the roller moves freely through its full arc before restoring power. Inspect the actuating cam or dog alignment to ensure proper switch actuation at the intended travel position.
