Square D 9007HA20 Adjustable Roller Lever Limit Switch

Product Description

The SQUARE D 9007HA20 is an adjustable roller lever designed as an accessory for limit switches in industrial and commercial control applications. The lever features a steel body with a Delrin roller, measuring 0.88 inches in overall length and 1.63 inches in diameter. This type of actuator accessory allows technicians to fine-tune the mechanical actuation point of a limit switch, enabling precise position or travel detection in automated equipment, conveyor systems, and machinery control circuits. Installation is performed by licensed electricians and industrial controls technicians during equipment setup or maintenance.

This roller lever is intended for use with compatible limit switches in industrial automation, machine control, and position-sensing applications. It fits systems where adjustable mechanical actuation is required to detect the presence, absence, or end-of-travel position of moving components. The Delrin roller provides durable contact with actuating cams or surfaces in repetitive-cycle environments.

Installation Notes

Installation of limit switch accessories should be performed by a qualified electrician or industrial controls technician. De-energize all circuits and lock out the equipment per LOTO procedures before removing or installing any switch actuator component. Verify the lever is fully seated and secured to the switch body before returning the equipment to service. Consult the limit switch manufacturer documentation for proper actuator mounting torque and adjustment range.
