Track machine extension from short strokes to 20 meters

How does a draw-wire transducer work?

A steel wire extends from a spring-return drum as the machine moves. The drum rotates with the wire, allowing the sensor to report linear displacement. Select CANopen models with an optional inclinometer when the same installation must also report angle.

Match measurement range and output

Choose travel first, then the signal your controller accepts. Analog models provide voltage or 4–20 mA options; the 5 m relay model gives a switching output. CANopen models add digital feedback, with CANopen Safety or SAE J1939 in specified configurations.

Where a value also includes an angle, that measurement depends on the chosen configuration. FS means full scale; life-cycle figures are specified at 25°C.

Available output, connector, angle and safety combinations depend on the exact model configuration.

Where do cable transducers help?

On cranes and aerial work platforms, extension feedback tells the controller how far a boom or stabilizer has moved. On construction and agricultural equipment, the same measurement can track actuator or implement travel. A model with inclination feedback can report both extension and tilt where the machine design requires them.

Quick selection checklist

1. Define travel: minimum and maximum extension in meters.
2. Decide on angle: linear position only or extension plus inclination.
3. Match the signal: voltage, 4–20 mA, relay, CANopen or a specified SAE J1939 option.
4. Check the environment: temperature, ingress protection, shock, vibration and expected operating cycles.
5. Confirm the exact configuration: supply voltage, connection, available range and any required safety approval.
