Linear Position Sensor – 1″ – 150mm Travel Length: Between Mounting Holes (Closed) 277mm

Standardized Chassis Feedback: Linear Position Sensor (150mm)

For high-performance road and circuit vehicles, the Linear Position Sensor with 150mm Travel is the industry standard for monitoring suspension dynamics and steering angle. With a 277mm distance between mounting holes when closed, this sensor is perfectly sized for K-swap time-attack cars and RB26-powered builds running standard-travel coilovers. It provides a precise 0-5V signal that tracks every nuance of wheel movement, allowing for advanced standalone ECU integration strategies that improve both handling and safety through traction control and aerodynamic rake management.

Engineering Principles: Precision Displacement Sensing

This sensor functions as a high-fidelity linear potentiometer, converting the mechanical displacement of its rod into a variable voltage output. This Analogue-to-Digital interface (regarding the ride height signal) allows the ECU to identify exactly where the car is in its suspension cycle. The IP65 rating ensures that the internal electronics remain sealed against the dirt, oil, and moisture common in a race car wheel well. This is vital for harness integration in professional motorsport, as it ensures the suspension telemetry remains consistent pull after pull, with no signal dropouts even under extreme vibration or thermal cycling.

Operational Benefits: Aero Rake and Load Management

Integrating a 150mm linear sensor with a Haltech Elite or Nexus series ECU enables sophisticated 4D fuel map calibration offsets. For example, in high-downforce applications, the ECU can use ride height data to adjust the boost target via closed-loop boost control to account for the increased rolling resistance of the aerodynamic load. Additionally, this data is used to optimize traction control; by detecting the speed of suspension compression, the ECU can predict the onset of tire loading, allowing for more aggressive power delivery. The included Nylon mounting bolts (recommended) provide electrical isolation, which is critical for preventing EMI from interfering with the ECU’s timing calculations.

Installation and Modular Integration

The 150mm sensor is a universal performance component that suits all ECUs with a spare AVI. It features a compact design that fits easily in tight areas like steering racks or between the chassis and control arms. The kit includes the sensor and a matching opposing connector set for a professional harness integration finish. During installation, ensure the mounting points are spaced exactly at the 277mm closed datum to maximize the usable 150mm stroke. This hardware is a mandatory requirement for any build utilizing an iC-7 Digital Display for real-time monitoring of vehicle dynamics.
