Buyer guide
Draw Wire or Magnetic Sensor?
Draw wire systems (also called cable-extension or wire-actuated encoders) have a stainless wire wound on a spring-loaded drum. The wire end is fixed to the moving part, and an encoder or potentiometer on the drum shaft converts wire travel into position. They measure long strokes, are easy to retrofit and need no precise alignment. The Encometer EM series and the robust XT12 and XT18 series on this page are draw wire systems.
Magnetic linear sensors read a magnetised tape fixed along the axis. The sensor head moves over the tape without touching it, so there is no wear, and it tolerates oil and dust better than optical glass scales. Keep the gap between head and tape within the stated limit. The MSA model gives absolute position; incremental models need a reference after power-on.
A digital readout (DRO) such as the VIMS display shows the position to the operator on manual machines.
What to Tell Us When You Order
- Measuring length: the full stroke, plus some margin.
- Resolution and accuracy: what the process actually needs.
- Output: incremental pulses, absolute (such as SSI), analogue 4–20 mA or 0–10 V, or potentiometer.
- Environment: oil, coolant, dust, outdoor use, temperature.
- Mounting: available space and how the moving part travels. Draw wire must pull straight out of the housing.
- Display: whether you need a DRO, and how many axes.
Photos of the machine axis and any existing sensor help us suggest the right system quickly.

Frequently Asked Questions
What linear measurement products do you supply?
This page lists draw wire measurement systems (Encometer EM4, EM8 and EM10, and the XT12 heavy duty and XT18 robust series), magnetic linear measuring sensors (MSA absolute, MSM, MSL and MSH) and the VIMS digital readout with magnetic sensor. Send the model you need or your application details to confirm availability.
What is a draw wire sensor used for?
A draw wire sensor measures linear position by pulling a wire off a spring-loaded drum attached to an encoder or potentiometer. It is used where strokes are long or mounting space is awkward, for example hydraulic cylinders, lifting platforms, gates, presses, forklifts and test rigs. It is easy to retrofit because only the housing and wire end need fixing.
How accurate is a magnetic linear sensor compared with a glass scale?
Glass scales generally give the highest accuracy and are used on precision machine axes. Magnetic sensors give good accuracy for many machine and automation tasks, tolerate dirt, oil and vibration better and allow longer lengths. Accuracy depends on the tape quality, mounting and head gap, so state your accuracy requirement when you enquire.
Can I add a digital readout to a manual machine?
Yes. A magnetic sensor with a DRO, such as the VIMS digital readout with magnetic sensor on this page, can be fitted to manual lathes, milling machines and special machines. Tell us the number of axes, travel lengths and the space available for the tape and sensor head.
Which output signal should I choose?
Choose what your controller or display reads. Analogue 4–20 mA or 0–10 V is simple for PLC analogue inputs. Incremental pulses suit counters and DROs. Absolute outputs such as SSI give position at power-on without homing. When replacing a sensor, keep the same output so the controller needs no changes.
How do I install a draw wire sensor correctly?
Mount the housing so the wire pulls straight out of the exit, with no angle that rubs the wire against the housing. Never let the wire snap back freely, as this can damage the spring and drum. Protect the wire from cutting edges and weld spatter, and fix the wire clip securely to the moving part.
How do I get a quote?
Send the existing model code, or your measuring length, resolution, output and display needs, through our request a quote form, by email to contact@ekacnc.com or by phone. We will reply with the matching system, price and availability.
