Eltra Encoder
Eltra S.P.A. is the world leading rotary encoder sensor manufacturer since 1985. Rotary encoders measure and track changes in current object position. These modern and inexpensive sensors are successfully used in a wide array of industrial automation projects.
The Rotary Encoder tracks linear and angular movements converting them into electronic signals.

There are three major types of Eltra rotary encoders:

  • Incremental encoders
  • Absolute encoders
  • Linear transducers.

Eltra also manufactures potentiometers, accessories and components for improvement and service of the encoder equipment.

Eltra S.P.A.

For over 35 years Eltra SPA has been focusing on the rotary encoders development and production. Since 1985 the company has designed and released 5435 models of industrial automation sensors. With Italy- and Slovakia-based plants scoring 12000 units annually Eltra became the world leader in rotary encoder manufacturing. The company’ leading position is pillared by evergoing investment in R&D, advanced technology and skilled workforce. High degree of plant automation ensures the lowest production cost. Eltra ensures a strict quality gate for each device manufactured. As a result it managed to maintain the highest quality at lowest prices found on the market.

The company developed a global presence with the widest network of distributors and sales representatives. On every continent Eltra strives to satisfy customer needs with a broad variety of highly reliable and durable industrial automation rotary encoders. This allows Eltra to facilitate orders instantly with customers experiencing minimal downtime. Devices, parts and components are sourced quickly, promptly shipped to customers all around the globe.

Another major advantage the company gained in customized solutions. It has the ability to address and implement individual needs to customer specification.  

Eltra provides a complete range of encoder parts and accessories with regular and express delivery services.

Rotary Encoder

This is a sensor which tracks linear and angular object displacements and converts them into electronic signals. Eltra encoder allows to track and measure an object position in a limited space.

Based on the zero point setting method, incremental and absolute encoders could be distinguished.

Incremental encoders require a zero point manually set. Absolute encoders determine a zero position independently.

Depending on the way an object position is measured and corresponding data gathered there are optical and magnetic types of sensors. Optical sensors provide the position data through changes of the code wheel position catched by a photo receiver. Magnetic sensors output the position data through tracking changes in magnetic fields produced by sensor magnets.

Linear transducers measure and track changes in the object position along only one axis. Rotary encoders provide object position data in two-dimensional format.
