Draw Wire Systems for demanding applications

The high-quality draw wire systems expand on their proven economical standard draw wire systems with solutions for demanding applications from 0.25m up to 40m measuring length.

The core of a draw wire device is a drum mounted on bearings, onto which a wire is wound. Winding takes place via a dynamic spring mechanism using a constant force spring, which allows for a high traverse speed of up to 10m/s and high acceleration of up to 140 m/s2; this proves ideal for dynamic applications and offers a long service life of approx. 2 million complete cycles.

The construction is particularly robust and unaffected by environmental influences thanks to its titanium-anodised aluminium housing. The wire is made from stainless-steel with a diameter of 0.5mm and is thus exceptionally hard-wearing. The wire exit is free from wear thanks to a diamond-polished ceramic guide.
The wide temperature range from -20°C to +85°C as well as the optional IP67 protection rating permit use in difficult environmental conditions.

The draw wire system is suitable for various sensors and encoders with analog outputs  (0 to 10V, 4 to 20mA, potentiometer), incremental (push-pull, RS422), absolute (SSI, BISS) and Field bus (CANopen®, Profibus, DeviceNet, EtherCat) interfaces.

The systems have a linearity of up to 0.05% and can be supplied on request together with the relevant calibration certificate.  Mounting is effected quickly using just 2 screws. The versatile housing technology allows for various mounting options. Connection is via either cable or connector.
