Operational Limit Switch 89109GT – For High-Reach S-Series Lifts

🔹 Product Overview: Safety-Critical Position Sensor
The Operational Limit Switch with part number 89109GT (and its predecessor 89109) is a specialized, safety-critical electromechanical sensor designed for the robust and high-precision control systems of the Genie S-Series Ultra-High Reach Telescopic Boom Lifts.
Unlike standard interlock switches, this Operational Limit Switch is specifically engineered to signal the machine control module when the boom or chassis has reached a certain point necessary for operational sequencing, speed reduction, or stability transition. In high-reach machines like the S-100 through S-125, reliable position feedback is absolutely essential for safe operation within the massive working envelope.
As a high-quality aftermarket replacement supplied by RQ Parts, this 89109GT Limit Switch offers an exact-fit solution to replace a worn, damaged, or failing original sensor. Failure of this switch can lead to system faults, limited movement, or machine lockout. Replacing it ensures accurate position signaling and consistent, safe sequencing across your high-reach Genie S-Series fleet.
