Linear Position Sensor – 1/2″ – 150mm Travel Length: Between Mounting Holes (Closed) 267mm

Standard Telemetry Precision: 1/2″ Bodied Linear Position Sensor (150mm)

The Linear Position Sensor with 1/2″ Body and 150mm Travel is the industry’s most popular slimline choice for professional suspension and steering telemetry. Featuring a 267mm closed mounting length, this sensor is perfectly optimized for Time-Attack, Hillclimb, and high-performance K-swap road racers. It provides a linear 0-5V signal that tracks every nuance of wheel movement, allowing for advanced standalone ECU integration strategies that maximize mechanical grip and aerodynamic downforce. This 1/2″ bodied instrument is designed for builders who require laboratory-grade data without the bulk of traditional sensors.

Engineering Principles: High-Cycle Signal Fidelity

A high-performance linear sensor must maintain its accuracy over millions of cycles. This 150mm travel sensor utilizes a low-friction internal wiper and a precision-ground resistive element to ensure consistent output. This Analogue-to-Digital interface (for chassis load sensing) is critical for fuel map calibration compensations that rely on ride height. The sensor is IP65 rated, making it impervious to the wheel-arch environment of intense heat, moisture, and road spray. This level of durability is foundational for harness integration in professional circuit racing, where consistent feedback is required to optimize traction and detonation protection via load management.

Operational Benefits: Aero Loads and Dampening Analysis

Integrating 1/2″ 150mm sensors with a Haltech Elite or Nexus system allows the tuner to implement sophisticated Traction Control logic based on damper velocity. By calculating the speed of suspension travel, the ECU can identify surface irregularities and adjust Ignition Timing or boost targets via closed-loop boost control to maintain tire contact. Additionally, this data is used to maintain the vehicle’s aerodynamic rake angle, which is essential for ensuring that the front splitter and rear diffuser are operating at maximum efficiency. The recommended use of nylon mounting bolts prevents EMI and ground loops from corrupting the delicate analogue signal.

Installation and Modular Integration

This sensor is a universal component that suits all ECUs with a spare AVI. Its compact 267mm closed length and slim 1/2″ body make it ideal for mounting in tight suspension configurations where interference is a risk. The kit includes the sensor and a matching opposing connector set for a professional harness integration finish. During installation, it is critical to align the sensor plunger with the suspension’s line of movement to prevent side-loading. This hardware is a mandatory requirement for any professional build utilizing an iC-7 Digital Display to monitor wheel travel and steering angle in real-time.
