Linear Position Sensor – 1/2″ – 250mm Travel Length: Between Mounting Holes (Closed) 367mm

Slimline Telemetry Interface: 1/2″ Bodied Linear Position Sensor (250mm)

When measuring extensive suspension travel in high-performance racing, space and weight are always at a premium. The Linear Position Sensor with a 1/2″ Body and 250mm Travel is a precision-engineered slimline instrument designed for deep-stroke measurement. Featuring a 367mm distance between mounting holes when closed, this 1/2″ bodied sensor is the definitive solution for measuring suspension travel on Formula cars, sports prototypes, and high-end LS-swap drag cars. It delivers a high-resolution 0-5V signal to your standalone ECU integration, providing the data needed for world-class chassis dynamics and aerodynamic analysis.

Engineering Principles: 1/2″ High-Density Architecture

The 1/2″ body diameter represents a significant reduction in mass and footprint compared to standard 1″ sensors, without sacrificing signal resolution. This sensor utilizes a high-durability internal potentiometer to translate linear movement into an analogue voltage. This Analogue-to-Digital interface (concerning wheel position) is essential for fuel map calibration compensations that rely on ride height. Despite its slender profile, the sensor maintains an IP65 Ingress Protection Rating, ensuring it survives the heat, moisture, and road spray of professional motorsport. This is a foundational component for builders who require the highest level of suspension telemetry in a space-constrained environment.

Operational Benefits for Aero and Traction

Integrating a 1/2″ 250mm linear sensor with a Haltech Nexus or Elite system allows for advanced closed-loop boost control strategies based on vehicle attitude. In high-horsepower 2JZ or RB26 builds, the ECU can identify when the chassis has “unloaded” through deep travel, allowing for an instant torque reduction to maintain traction control targets. Furthermore, this data is used to validate aerodynamic maps, ensuring that the ride height remains within the window where downforce is maximized. The use of nylon mounting bolts (recommended) provides electrical isolation, ensuring your data remains free from EMI generated by the ignition system.

Installation and Harness Integration

This 1/2″ bodied sensor is a universal performance component that suits all ECUs with a spare AVI. Its 367mm closed length must be considered during chassis fabrication to ensure the sensor does not bottom out. For a professional harness integration, the sensor includes an opposing connector set. Installation is straightforward, utilizing two mounting holes for a secure radial fit. It is essential to ensure that the actuating rod is aligned perfectly with the movement of the suspension arm to prevent binding. This sensor is the ultimate choice for engineers who demand maximum travel data in a minimal package.
