EMETA introduce a contactless potentiometer with extended useable life!
To measure an absolute position on a rotary movement can absolute encoders be used. Such sensor has been offered by EMETA Encoders since many years. In measurement systems with lower grades of complexity may such motions also be detected and measured by analogue potentiometers. Such kind of sensors has historically not been offered by EMETA until now. In conjunction with the ELMIA Wood fair 2017 is EMETA launching its first family of contactless potentiometers with analogue interfaces. The series is called MP22.
Reliable magnetic scanning principle
On big advantage with the radiometric contactless potentiometer is its useable life. Compared with conventional potentiometers is the lifetime increased significantly. This is due to the fundamental design of the scanning principle. On a conventional potentiometer is the resistance alternated by mechanical contacts inside the potentiometer. Therefore subject to mechanical wear, On EMETA’s MP22 is the scanning done by two individual components. One rotating magnet and one separate pick up unit. Completely free from contact between each other and no bearings are used. The design of the magnetic part is available in many different shapes and types. Please contact us to find the most suitable arrangement for your application.
When the magnet rotate is the pick up unit detecting the induced alternating magnetic field. This is afterwards converted into an analogue voltage representing the angle position of the magnet. The electrical interface of the MP22-series is a simple voltage with 0..5 Vdc or 0.5 to 4.5 Vdc amplitude. The active angle over which the full scale output is generated is programmable upon manufacturing. The user’s simply need to specify which active angle their model should have. Range can be programmed between 5 to 360º. Please review the picture above to learn more about how the output of the MP22-potentiometer is designed.
Robust design for tough environments
The MP22-potentiometer is extremely robust thus with limited dimensions. Therefore may the sensor be used in very space limited applications. Such as integrated in industrial joysticks or other control equipment.

EMETA is proud to announce its latest addition to our popular MA400-family. The new feature consists of a combined incremental encoder with integrated mechanical overspeed monitor.
MA450, as the new model is called, consists of two separate units integrated in one and the same rugged AISI 316 stainless steel enclosure with encapsulation class IP67. Partly it includes an incremental encoder with high resolutions, but also the mechanical speed detection unit.
Modern motion control applications often require an incremental encoder for feedback of speed or velocity information used on large motors or generators. In many applications, such as main engines in steelworks, hoisting motors on harbor cranes and the like, also requires a separate redundant mechanical speed monitoring device for safety reasons. To protect machinery failing but equally to prevent dangerous faults cases to arise. For all such applications is the MA450 Series absolutely a perfect product!
The new encoder solution with integrated mechanical speed monitor, is based on proven technology. By the use of a normally closed contacts which open and close at a pre-defined speed value, ensures that the surveillance system or the external brakes can rely on redundant information from the sensor unit. The speed monitor can break up to 3A at 230V and be used at speeds up to 4000 rpm.
