This document describes the features and characteristics of the Magnetic Length Sensor MLS-8. The sensor consists of two shifted Wheatstone bridges assembled on a ceramic hybrid. The measurement precision of the sensor depends on the distance between the sensor and the pole stripe.
The MLS-8 magnetic length sensor uses two shifted Wheatstone bridges on a ceramic hybrid to generate sine and cosine output signals. A magnetic scale with a 2.5 mm pole distance and a pole stripe moving within 1.5 mm of the sensor enables precise distance detection through sine/cosine analysis.
The device operates from a 5‑10 V supply, provides a sensor resistance of 30‑50 kΩ, and works within –40 °C to +85 °C operating temperature. Its compact dimensions are 17.8 × 8.1 × 2.2 mm, making it suitable for high‑resolution length measurement applications.
