AiM Eclipse 150mm Linear Potentiometer

The AiM ECLIPSE is a motorsport-grade linear potentiometer built for car and bike racing. Use it to log damper compression/extension or steering rack displacement on any AiM data logger. It's quick to install and delivers excellent accuracy, repeatability and service life.

Inductive Contactless Technology

No physical contact inside the sensor means virtually no wear — performance stays consistent for the life of the unit (25+ million cycles).

Lightweight, Tough Materials

The housing is fiberglass-reinforced epoxy: strong under mechanical stress and heat cycling, flame resistant, self-extinguishing and an excellent electrical insulator. The shaft is extruded carbon fiber instead of steel, keeping weight down to just 20–40 g without giving up strength.

Built-In Diagnostics

Signal output runs 500–4,500 mV so faults are easy to spot in your data:

• Reading below 100 mV = fault (open circuit)
• Reading above 4,900 mV = fault (short circuit)

Easy Setup in RaceStudio 3

The RaceStudio 3 configuration panel lets you set the sensor parameters and quickly choose whether it reads extension or compression.

Joint Options

• Ball Joint (Rod End) – Part # X05ELP150ABJ. Rod-end style ball joints on both ends for a fixed, secure mount.
• Quick Release Pop Joint – Part # X05ELP150APJ. Snap-on joints for fast removal and reinstall between sessions.

Installation Notes

• Connects to any analog channel on AiM loggers.
• Don't overtighten the mounting hardware — bending the internal cylinder can damage the sensor.
• Extend the shaft about 5 mm (0.2") from the fully retracted position when mounting.
• Do not use beyond the sensor's maximum travel.
• EVO4S and Channel Expansion require an extension cable (V02PCB__BTXG series). MXL2, MXS/MXG/MXP, EVO5, PDM and similar use the V02PCB__B series. Available 500–3000 mm.
