Square D AL1650 Limit Switch Roller Lever Arm 7.6 in

Product Description

The SQUARE D AL1650 is a replacement roller lever arm designed for use with Square D L525 series limit switches. This accessory extends the mechanical actuation reach of the limit switch, allowing the roller to contact a cam, ramp, or machine surface and trigger the switch mechanism. Limit switch lever arms are standard components in industrial and commercial control panel applications, conveyor systems, machine guarding, and automated equipment. The AL1650 features a nylon roller and measures 7.6 inches in overall length. Installation is performed by licensed electricians or qualified industrial maintenance technicians familiar with control circuit components.

This roller lever arm is intended for use in machine tool, material handling, and automated control applications where a limit switch requires a longer actuation arm to reach the target surface. It is specifically listed for use with the L525 limit switch series. The nylon roller construction reduces wear on the actuating surface and operates reliably across typical industrial duty cycles. This part is suited for both new installations and field replacement of worn or damaged lever arms on existing L525 assemblies.

Key Features

• Nylon roller construction reduces actuating surface wear
• 7.6 inches overall length provides extended mechanical reach
• Direct replacement accessory for L525 series limit switches
• Lightweight at 0.3 pounds for easy handling and installation
• Package quantity of 1 for single-unit replacement jobs

Compatibility

Designed for use with the Square D L525 series limit switch. Verify lever arm attachment compatibility with the specific L525 variant in service before installation.

Installation Notes

Installation should be performed by a qualified electrician or industrial maintenance technician in accordance with applicable NEC requirements and equipment manufacturer guidelines. De-energize and lock out the control circuit before removing or installing any limit switch component. Confirm the lever arm is fully seated and secured to the switch body before returning the machine to service. Do not operate the switch beyond the rated mechanical travel of the lever arm.
