Draw wire encoding systems

August 2011 Sensors & Transducers

Kübler offers efficient and high-quality draw wire systems for demanding applications from 25 cm to 40 m measuring length. The core of the 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, which allows for high traverse speeds of up to 10 m/s. This is ideal for dynamic applications and offers long service life.

The construction is particularly robust and unaffected by environmental influences thanks to an anodised aluminium housing, wire made from stainless steel and an exceptionally resilient wear free exit guide. The wide temperature range of -20 to 85°C coupled with an IP67 protection rating permit use under harsh environmental conditions.

The system is equipped with a variety of outputs: analogue (0-10 V, 4-20 mA, potentiometer); incremental (push-pull, RS422); absolute (SSI, BISS) and fieldbus (CANopen, Profibus, DeviceNet, EtherCat).

Linearity is 0,05% and the versatile housing technology allows for various mounting options. Connection is via cable or connector.
