Linear Position Sensor - 1" - 100mm Travel Length: Between Mounting Holes (Closed) 227mm

Overview

The Haltech Linear Position Sensor delivers precise measurement of suspension travel, steering rack position, or gearbox shift fork movement with 1" (25mm) of travel in a robust IP65-rated package. Essential for data logging race suspension setups, monitoring steering inputs during track sessions, or feedback control in advanced sequential gearbox applications.

Why You Need This

Proper suspension data logging transforms guesswork into precise setup knowledge. This linear position sensor mounts between suspension components to measure real-time travel, revealing whether your damper setup matches track demands or if you're hitting bump stops under braking. On track-focused builds like time attack Evos or circuit-prepared M3s, suspension travel data correlates directly with lap times — too little travel means you're riding the stops, too much indicates the car isn't using its available grip.

The 25mm travel range suits most racing applications where you're monitoring specific movement ranges rather than full suspension stroke. The IP65 rating handles trackside conditions, wheel well spray, and pressure washing. Unlike basic mechanical gauges, this sensor feeds real-time data to your Haltech ECU for logging alongside engine parameters, creating a complete picture of vehicle dynamics. Perfect for sequential gearbox position feedback, steering angle measurement for traction control systems, or brake bias adjustment monitoring.

ECU & System Compatibility

Compatible with all Haltech Elite and Nexus ECUs featuring analogue voltage inputs — Elite 550, Elite 750, Elite 1000, Elite 1500, Elite 2000, Elite 2500, Nexus R3, and Nexus R5. Connect to any spare analogue input and configure scaling through NSP software for direct dashboard display and data logging integration.
