Linear position sensor LTM-A Series

Image LTM-A

The LTM-A Series works with a potentiometric principle and with embbedded electronic circuitry, the LTM-A series outputs 4-20mA signal (3-wire).

Thanks to its high resolution of 0.01 mm, precise measurements can be made. Since they are analogue outputs, they operate as a absolute sensor, ie they do not lose their position during power / power cuts and continue to measure from where they left off.

The linearized conductive plastic (Carbon + Plastic alloy) resistive alloy and special contacts are not affected by abrasion and operate for long periods with motion lives of up to 100 million. Because they make the resistance change linear by special methods, they make stable and equal measurements every time.


  • Easy installation via adjustable connecting legs on the body
