Square D 7D Adjustable Roller Lever Limit Switch

Product Description

The SQUARE D 7D is an adjustable roller lever actuator designed as an accessory for compatible limit switches. The lever measures 1.38 inches in overall length with a 0.25 inch diameter roller, and features a metal roller construction for reliable actuation in industrial and mechanical control applications. This type of actuator converts linear or rotational mechanical motion into a switch signal, making it a working component in position sensing and machine control circuits. It is installed by electricians and controls technicians as a replacement or supplemental actuator arm on limit switch bodies.

The 7D adjustable roller lever is suited for use in industrial controls, HVAC equipment, conveyor systems, and other machinery where a limit switch monitors position, travel, or end-of-stroke conditions. The adjustable design allows the installer to set the lever angle and actuation point to match the specific mechanical arrangement of the equipment. The metal roller provides durability against repeated mechanical contact under normal service conditions.

Key Features

• Adjustable lever angle for flexible actuation positioning
• Metal roller construction for durability under repeated mechanical contact
• 1.38 inch overall length fits standard limit switch actuator mounts
• 0.25 inch roller diameter with 0.25 inch face width
• Sold individually as a single replacement part

Compatibility

Designed for use with compatible limit switches as an actuator accessory. Verify actuator thread size and mounting interface against the specific limit switch body before ordering.

Installation Notes

Installation of limit switch actuators should be performed by a qualified electrician or controls technician. De-energize and lock out the circuit and any associated machinery before removing or installing actuator components, following applicable NFPA 70E and OSHA lockout/tagout procedures. Confirm the lever mounting is secure and the actuation angle is set correctly before returning the equipment to service. Do not force the lever beyond its mechanical adjustment range.
