Repeatable Length Measurement

Many applications require linear motion to be monitored for system control or to ensure safety. With lengths ranging from 1 m to 30m (3’ to 98’), LINARIX linear sensors are available in many configurations to meet an application’s requirements. Options include a wide variety of outputs (including analog, fieldbus and Ethernet variants), heavy duty housings and compact design.

  • Wide Selection of Measuring Lengths
  • Absolute Position Measurement with Resolutions up to 2 μm
  • High Linearity even with Long Cycle Times
  • Low Cost yet Rugged Construction
  • Scalable Analog Output to Fit Measuring Length

POSITAL’s LINARIX draw wire sensors measure linear motion by displacing a stainless steel wire A wound around a wire drum B that actuates the rotary C encoder coupled to it via coupling D. A spring E is used to retract the wire in the housing. The encoder provides a proportional output. Measurements are highly accurate, reliable and the systems have very long lifetime.

The LINARIX line is featured with different mechanical options, housing materials and springs to enable you to always find the most suitable product for your application.

Extruded Metal Housings for Linear Sensor

This robust aluminum draw wire with flexible mounting options is suitable for demanding environments. Flexible mounting options make installation easy in a variety of applications. Suitable for applications that require high acceleration, up to 7g. Available in 3 [118 in], 5 [196 in], 10 m [393 in] and 15 m [590 in] measuring length.


Machined Metal Housings Draw Wire Sensor

The aluminum housing provides a reliable sensor ideal for industrial environments. Being both economical and compact, these are appropriate for a wide variety of applications. Available in 1.74 m [ 68.5 in], 3 m [118 in] and 6 m [236 in] measuring lengths.


Plastic Housings for Draw Wire Encoder

Unbeatable economic pricing in large quantities and a small footprint makes this tough draw wire encoders the preferred OEM customer selection. Well engineered mechanics in combination with POSITAL’s fully digital rotary encoders means these draw wires do not loose accuracy even after one million strokes. Available in 2.4 m [94.49 in] and 7.5 m [295.28 in] measuring lengths.

Compared to conventional linear pots and linear measurement systems using multiple gears and encoders LINARIX line are more durable and can be used to replace them directly avoiding common problems of slippage and wear. Draw wire sensors from POSITAL provide extremely precise measurements because of inherent accuracy of encoders while rugged construction ensures reliable performance even under extreme conditions.
