Square D 9007HA4 Adjustable Roller Lever Limit Switch

Product Description

The SQUARE D 9007HA4 is an adjustable roller lever accessory designed for use with industrial limit switches. It provides a mechanical actuating arm that translates physical contact or motion into a switching signal, allowing the limit switch to detect position, presence, or travel limits in automated equipment and machinery. The lever body is cast zinc with a nylon roller, measuring 0.88 inches in overall length and 0.63 inches in diameter. It is installed by electricians and automation technicians as a replacement or reconfiguration part on limit switch assemblies.

This roller lever is intended for use with compatible limit switches in industrial, commercial, and light manufacturing environments. Typical applications include conveyor systems, machine guarding, door and gate position detection, and other electromechanical control setups where a lever-style actuator is required. The adjustable design allows the technician to set the actuating angle to suit the specific installation geometry.

Key Features

• Cast zinc lever body for durability in industrial environments
• Nylon roller reduces wear on actuating surfaces during repeated contact cycles
• Overall length of 0.88 inches suits compact limit switch mounting configurations
• Overall diameter of 0.63 inches for precise fitment to compatible switch heads
• Adjustable roller position allows alignment to the required actuating angle
• Sold as a single unit (package quantity of 1)

Compatibility

Designed as an OEM-style replacement or accessory lever for use with compatible limit switches requiring an adjustable roller lever actuator.

Installation Notes

Installation should be performed by a qualified electrician or industrial maintenance technician. De-energize and lock out the circuit before removing or installing limit switch components, following NFPA 70E lockout/tagout procedures. Verify that the replacement lever is fully seated and secured before restoring power and testing actuator travel. Confirm the adjusted roller angle does not cause over-travel or under-actuation of the switch mechanism.
