Linear Position Sensor – 1/2″ – 200mm Travel Length: Between Mounting Holes (Closed) 317mm

High-Resolution Chassis Sensing: 1/2″ Bodied Linear Position Sensor (200mm)

In high-end performance electronics, the goal is always to minimize weight while maximizing data resolution. The Linear Position Sensor with a 1/2″ Body and 200mm Travel is a precision measurement tool designed for advanced suspension telemetry. Featuring a 317mm distance between mounting holes when closed, this slimline sensor is specifically engineered for GT3, Formula, and high-performance LS-swap chassis where mounting space on the uprights or control arms is limited. It provides a linear 0-5V output to your standalone ECU integration, delivering sub-millimeter resolution for every combustion cycle.

Engineering Principles: Slimline Signal Accuracy

The 1/2″ bodied sensor utilizes a high-density internal potentiometer to translate linear movement into a proportional voltage. This Analogue-to-Digital interface occurs with minimal internal friction, providing a clean signal that is vital for accurate ride height monitoring. With its IP65 Ingress Protection Rating, this sensor is engineered to survive the intense thermal and mechanical stresses of professional racing, including high-frequency vibrations and exposure to oil and brake dust. This reliability is foundational for harness integration, ensuring that your traction control and aerodynamic maps are backed by unwavering data.

Operational Benefits for Competitive Tuning

Integrating a 1/2″ 200mm linear sensor with a Haltech Elite or Nexus series ECU enables the implementation of high-tier Traction Control logic. By monitoring the rate of suspension compression, the ECU can identify tire slip before it becomes audible, allowing for millisecond-perfect timing or boost reductions via closed-loop boost control. For builders of RB26 or 2JZ track cars, this data is essential for maintaining the car’s aerodynamic rake at high speeds, which is the key to consistent corner entry and exit speeds. The recommended use of nylon mounting bolts ensures that the sensor signal remains free from chassis ground noise and EMI.

Installation and System Requirements

This 1/2″ sensor is a universal component that suits all ECUs with a spare AVI. Its 317mm closed mounting distance provides a stable mechanical datum for setup. The sensor includes an opposing connector set, facilitating a professional harness integration that meets motorsport standards. Proper installation requires mounting the sensor body to a rigid point on the chassis and connecting the rod to the moving suspension member. It is critical to ensure the travel remains parallel to the shock travel to avoid side-loading the sensor’s internal bushings, which can lead to signal hysteresis or premature failure.
