Leine & Linde's Robust New MRI 2850 Encoder Offers Enhanced Performance for Vector Motor Control



Schaumburg, IL - Leine & Linde introduces a new bearing-less encoder for high horsepower electric motor applications using vector control.  Called the MRI 2850, this encoder is of particular use as a motion feedback solution in applications such as large rotating machinery typically found in the construction, pulp & paper, oil & gas, wind and marine industries.



The MRI 2850 is a particularly hardy encoder, offering stable outputs and robust line drivers with a unique code-wheel securing mechanism. The lightweight aluminum enclosure reduces the effort for installation and is coated to prevent corrosion.



Designed for mounting on a NEMA standard 8.5” C-Face, the sensor technology provides extremely compliant tolerances. One or two independent read-heads can be provided, each with any resolution between 1 and 16383PPR. The IP67-protected read-heads include power and status LEDs so proper mounting and operation can be visually determined at any time.



The robust electronics include advanced sensing technology to assure stable speed measurement without ripple or ghost pulses, and without the need for special shielding. In addition, the tough output divers can support signal frequencies up to 100kHz at 30V over 350m cable lengths.



The magnetic code-wheel on the MRI 2850 supports shaft sizes from 1” to 4” without the need for a stub shaft.  Magnet material is permanently covered with a stainless steel shield so that damage from mechanical contact is eliminated.
