MCD-4 Posital Magnetocode Rotary Encoder

Packaging Machinery

Absolute multi-turn through-shaft rotary position sensing is key to the coordination of the multiple functions of modern consumer packaging machinery.

Roll-Up Commercial Doors

PLC controlled powered overhead door operation requires a heavy duty through-shaft analog outpu rotary position sensor enhanced with field programmability.

Multi-Axle Steer-By-Wire Systems

Multi-axle main steering and steering on rear or articulated axles requires ultimately reliable, accurate steering shaft position sensing over multiple turns.

The Posital Magnetocode MCD-4 is a robust contactless, non-mechanical (sensor), multi-turn 20mm through-shaft, magnetic absolute rotary encoder engineered to provide reliable analog current, voltage, or a variety of digital outputs over the sensor’s up to 7200° (20 turn "useable") measuring range while operating in a military/heavy duty automotive environment. Based on contactless Hall Effect sensing and patented Wiegand Wire magnetic absolute turn counting technology (no battery back-up required), the MCD-4 features 12 bit (single turn) resolution and unique field programmability for gain and offset, totally eliminating the need for time consuming physical adjustment upon installation. Contactless sensors such as the MCD-4 are not subject to wear of the sensor element and experience no output signal deterioration over the life of the sensor.
