All positioning tasks in factory automation and construction require current and precise position values
to monitor motion activity. Absolute rotary encoders mark every step of movement by a unique digital signal. This ability to assign distinct and exact values to linear and angular positions at any time has made absolute rotary encoders a pivotal means of connection between the mechanical system and the control system.

Magnetic rotary encoders determine positions using the Hall effect sensor technology developed for the automotive mass market. A permanent magnet fixed to the shaft generates a magnetic field that is sampled by the Hall sensor, which translates the measured value into a unique absolute position value. (more info)

Posital optical encoders are made up of a revolving shaft with a code disc and an optoelectronic scanning unit consisting of a screen and photoreceptors. Infrared light from an LED source passes through the code disc and the screen behind it. At every angle position a different sequence of photoreceptors are blocked from light by dark segments on the code disc. (more info)

Platinum electrodes are deposited in pairs on the base of the sensor`s cell parallel to the sensitive axis. The chamber is partially filled with an electrolytic liquid. When an alternating voltage is passed between two electrodes, the electric current will create a dispersed field. (more info)
