Draw-wire sensors of the wireSENSOR series measure with high linearity across the entire measuring range and are used for distance and position measurements of 50mm up to 50,000mm. Draw-wire sensors from Micro-Epsilon are ideal for integration and subsequent assembly in serial OEM applications, e.g., in medical devices, lifts, conveyors and automotive engineering.

Compact and robust design

Different sensor series cover numerous measurement tasks in different industries. The wireSENSOR MK series is very favorably priced and suitable for the integration into restricted installation space due to the miniaturized design. The wireSENSOR P series is extremely robust and used in applications with large measuring ranges.

Reliable operation and long service life

Draw-wire displacement sensors measure linear movements using a highly flexible steel wire. The cable drum is attached to a sensor element which provides a displacement-proportional output signal. Measurements are performed with high accuracy and high dynamic response. The use of high quality components guarantees a long service life and high operational reliability.

Telescopic measuring principle – ideal for difficult-to-access places

A clear advantage of this draw-wire measuring principle is that the measuring cable can be diverted over deflection pulleys. This property differentiates draw-wire sensors from other measuring principles which normally only measure on one axis. The sensor housings are kept extremely compact. The well-conceived sensor design enables large measuring ranges to be realized in a space-saving manner.

Customer-specific designs

More than 120 draw-wire sensors with different designs, measuring ranges and output signal types cover a wide range of applications. For special requirements that are not met by standard models, the draw-wire sensors can be suitably modified. A commercial implementation can already be achieved with medium-sized quantities.
