ELTRA products are becoming more and more popular thanks to the widespread adoption of automation and innovative technologies. Automation of production processes increases the accuracy and quality of parts manufacturing, increases the cost, reduces material consumption and costs, reduces the cost, dictates the use of special devices. The sensors provide control over the movement of working mechanisms during technological operations. The ELTRA sensor has become a mandatory component of most automated systems. The Italian company announced its presence in the market in 1985. The success of the enterprise consists of:
The main concept of the manufacturer is the optimization of the production cycle and the production of devices for individual conditions. All products undergo strict quality control and comply with international certificates. The expansion of the sales network made devices under the ELTRA brand famous not only in Europe, but also in Asia and the USA.
Encoders - provide accurate positioning of the drive and other mechanisms of machines, machines, aggregates, any industrial equipment. The manufacturer, studying the requirements of the market, constantly improves its products, offering products with new characteristics. An optical-based incremental encoder monitors the position and angular velocity of the moving shafts. The use of magnetic encoders provides increased positioning accuracy, and absolute encoders using a photocell are able to retain position data after the mechanisms are turned off. The manufacturer offers explosion-proof encoders and other sensors with special properties for specific requirements.
Linear and optical incremental systems provide maximum precision not only in motion control, but also in medical technology, synchronous / asynchronous motors, textiles, papermaking and many other areas. Linear potentiometers operate reliably even under harsh operating conditions and are easy to install and maintain.
Incremental encoders track the change in shaft position relative to the reference position regardless of the direction of rotation. Eltra has developed a wide range of incremental encoders of various types (optical or magnetic), various mountings with a wide measuring range. In addition to standard encoders, Eltra offers the ability to design and manufacture devices to meet individual customer requirements.

Eltra linear transducers are designed for tracking and measuring linear movements. The principle of operation is based on calculating the change in resistance created by the movement of a given object within an electrical circuit. Depending on the model, the transducers can have different mountings, be performed with or without zero mark, with several configurations of electronic outputs. The units are supplied with an integrated self-lubricating mechanism in a compact housing to ensure long life without any maintenance. Linear converters with rack and pinion EC34.

Other products and accessories - Eltra also manufactures a series of encoders with potentiometric output signal, mounted in a robust housing, fitted with two bearings. The product catalog contains EMB signal splitter boards, which are used to adapt encoders to control various devices. The main function of the EMB is output isolation, output stage trim and optical isolation of inputs. EMD sensor signal selectors are used to select a signal from one of the three inputs and transmit signals from one of them to the output. Eltra flexible couplings are essential elements for transmitting rotary motion on the sensor shaft. The couplings are made of aluminum alloy and consist of a cylindrical body with a helical groove to provide torsional rigidity and the ability to compensate for small shaft misalignments or absorb small axial shaft displacements.
