Project Description

Encoder based on a transmissive disk and an optoelectronic reading head.

Allow to have an absolute position each turn with a resolution of up to 21 bit.
An electronic multiturn counter can detect up to 65536 turns. Without power supply the multiturn counter has to be supplied
by an external back battery.
