Linear Position Sensor – 1/2″ – 100mm Travel Length: Between Mounting Holes (Closed) 217mm

Compact Displacement Precision: 1/2″ Bodied Linear Position Sensor (100mm)

In high-performance automotive diagnostics and control, the ability to measure short-stroke linear displacement is vital for accurate feedback. The Linear Position Sensor with a 1/2″ Body and 100mm Travel is a precision instrument designed for professional standalone ECU integration. Featuring a 217mm closed mounting distance, this compact sensor is the definitive choice for measuring steering angle on drift cars or brake pedal travel in GT-series race vehicles. It provides a linear 0-5V output, ensuring that your fuel map calibration and vehicle dynamics maps are based on high-fidelity, real-time data.

Engineering Principles: Slimline Hall-Effect/Potentiometric Logic

This sensor is built to deliver a smooth and consistent voltage output directly proportional to its 100mm mechanical travel. This Analogue-to-Digital interface (for positional feedback) allows the ECU to identify minute changes in control inputs, enabling advanced safety and performance strategies. Despite its small 1/2″ body diameter, the sensor features IP65 Ingress Protection, making it immune to the high-heat and moisture common in engine bays or near braking systems. This level of durability is foundational for harness integration in motorsport, where every signal must be pristine to avoid triggering ECU Trouble Codes during high-G maneuvers.

Operational Benefits: Steering and Control Loop Tuning

Integrating a 1/2″ 100mm linear sensor with a Haltech Elite or Nexus series ECU unlocks professional-level vehicle control. For builders of high-horsepower RB26 or 2JZ drift cars, using this sensor to monitor steering angle allows the ECU to implement steering-sensitive traction control. In circuit applications, this sensor is the key to perfecting the driver’s “brake-by-wire” or automated clutch control loops. The use of nylon mounting bolts (recommended) provides essential electrical isolation, protecting the ECU’s sensitive inputs from the EMI generated by high-power ignition systems.

Installation and System Requirements

This 1/2″ sensor is a universal component that suits all ECUs with a spare AVI. Its compact 217mm closed mounting length makes it ideal for installation in tight cockpits or steering assemblies. The kit includes an opposing connector set for a professional harness integration. During installation, it is critical to ensure the sensor’s mounting datum is rigid to prevent bracket flex from corrupting the 0-5V signal. A proper two-point software calibration within the Haltech NSP or ESP software ensures the sensor perfectly represents the physical travel of the component being monitored.
