Considerations for selecting draw-wire sensors
When selecting draw-wire sensors for your application, it’s essential to consider several key factors to ensure optimal performance and compatibility:
- Measurement range: Determine the necessary range of linear displacement for your application. Choosing a sensor that accurately measures the full extent of movement is essential for precise readings.
- Cable length and material: Assess the cable length and material. Ensure the cable is long enough for maximum displacement and durable enough to withstand environmental factors like abrasion and humidity.
- Output type: Consider the output signals of draw-wire sensors, including analog voltage, current, and digital formats. Confirm compatibility with your control systems for effective integration.
- Mounting and space requirements: Review the sensor’s dimensions and mounting needs to ensure it fits within your installation space and is easy to mount.
- Response time: The sensor’s response time may be critical for your application. For dynamic environments requiring real-time feedback, select sensors with faster response times.
- Environmental conditions: Evaluate the operating environment for factors such as temperature extremes, dust, moisture, and vibration. Choose a sensor designed to withstand these conditions.
By thoughtfully evaluating these factors, you can choose the ideal draw-wire sensor for your requirements, ensuring reliable performance and precise measurements for your application.

Frequently asked questions about Draw-wire sensors
Answers to the most important technical Questions
When should I use a draw-wire sensor?
A draw-wire sensor should be used when linear movements, positions, or distances need to be measured reliably over short to very long measuring ranges. It is particularly suitable when the measuring point is difficult to access, installation space is limited, or a robust sensor is required for dynamic movements. Typical applications include lifting and hoisting systems, cranes, mobile machinery, test benches, conveyor technology, hydraulic cylinders, and industrial automation. Draw-wire sensors are a good choice when simple mechanical integration, flexible cable routing, and a proportional output signal are required. We will be happy to help you select a suitable draw-wire sensor for your application, measuring length, and environmental conditions.
What measuring lengths can be achieved with draw-wire sensors?
Althen draw-wire sensors can achieve measuring lengths from 50 mm to 50 m. This makes them suitable both for short position measurements in compact machines and for long displacement and distance measurements, for example in lifting systems, crane systems, mobile machinery, or test benches. The appropriate measuring length depends on the available installation space, cable routing, required accuracy, and environmental conditions. If necessary, pulleys can be used for measuring points that are difficult to access. We will be happy to help you select a suitable draw-wire sensor for your measuring range.
How accurate are draw-wire sensors over long measuring distances?
Althen draw-wire sensors are suitable for long linear measuring distances of up to 50 meters and, depending on the design, can achieve an accuracy of up to 0.01 mm. They measure linear movement using a highly flexible measuring cable that is guided on a spring-loaded drum and generates a proportional displacement signal. The actually achievable accuracy depends on the selected measuring range, sensor type, resolution, output signal, and mechanical installation. For long measuring distances, clean cable routing, correct alignment, stable mounting points, and suitable environmental conditions are particularly important. Pulleys can also be used if the measuring point is difficult to access. We will be happy to help you select a suitable draw-wire sensor for long measuring distances and your accuracy requirements.
