Sensor Head / Electronics Module for Position Transducers

Product Specifications

Technical details and manufacturing context for Sensor Head / Electronics Module

Definition

The sensor head/electronics module is a critical subassembly of a position transducer that combines the physical sensing element with electronic circuitry for signal conditioning, processing, and output generation. It detects positional changes and converts them into standardized electrical signals. This module integrates the sensing element (e.g., coil, photodiode array) with a PCB and semiconductor components, all housed in a plastic or metal enclosure. The electronics amplify, filter, and convert raw sensor signals into standardized outputs such as analog voltage/current (e.g., 4–20 mA) or digital protocols (e.g., SSI, PWM). The module is designed for industrial environments, with a supply voltage of 9–36 V DC (reverse polarity protected), a measuring range of 0–1000 mm (custom ranges available), linearity error of ±0.05% FS (best straight line method), and repeatability of ±0.01% FS at constant temperature. Operating temperature for the electronics module is -40 to 85 °C, storage temperature -40 to 100 °C (non-condensing). Ingress protection is IP67 (mating connector required) per IEC 60529, and EMC compatibility is per EN 61326-1. Housing material is stainless steel 316L (ASTM A276). Weight ranges from 0.2 to 0.5 kg depending on cable length. This module is a component for use in position measurement systems; it is not a complete transducer. For specific applications, verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The sensor head/electronics module uses sensing technologies such as inductive, capacitive, or optical to detect position changes. The sensing element generates a raw signal that is amplified, filtered, and converted by integrated electronics into standardized outputs like analog voltage/current or digital protocols (SSI, PWM). The module requires a stable DC supply (9–36 V) and provides a 4–20 mA output in two-wire loop-powered configuration. The measuring range is 0–1000 mm, with linearity error ±0.05% FS and repeatability ±0.01% FS. The electronics are temperature-compensated for reliable operation from -40 to 85 °C. The module is housed in a stainless steel 316L enclosure with IP67 protection, suitable for industrial environments.
