The Genie 27391GT is a genuine OEM Proximity Sensor built for Genie telescopic and articulating boom lifts, including S-series, Z-series, and SX-series models. As a direct OEM replacement, this sensor is manufactured to Genie's original specifications, ensuring it integrates correctly with your machine's control system without adaptation. Compatible with a broad range of Genie booms — including S-65, S-65 TRAX, SX-135 XC, Z-45/25J Bi-Energy, Z-62/40, ZX-135/70, and many more — this part is the right choice when restoring accurate position detection to your machine. Cross-reference part number 27391GT against your serial-specific parts manual to confirm it is the correct sensor for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original design specifications for correct electrical output and dimensional fit, with no guesswork on compatibility.
- Direct Replacement Fit — Connects to the existing wiring harness and mounts to the original sensor location, restoring function without modification.
- Broad Boom Fitment — Fits a wide range of Genie telescopic and articulating boom lifts, including S-series, Z-series, and SX-series models across multiple configurations and power options.
- Restored Position Detection — A correctly functioning proximity sensor keeps the machine's control system informed of component position. A failed sensor can trigger fault codes, restrict machine movement, or prevent operation entirely.
A proximity sensor is a non-contact detection device that signals the machine's control system when a moving component — such as a boom section, axle, or platform — reaches a defined position. On aerial boom lifts, these signals are used to enforce operating limits, sequence movements, and trigger safety interlocks. When a proximity sensor fails or drifts out of calibration, the control system may receive incorrect position data, causing fault codes, restricted function, or a full machine lockout. Replacing a faulty sensor with the correct OEM part restores accurate signaling and returns the machine to normal, safe operation.
