Absolute Optical encoders TWK-ELEKTRONIK KRD series They have a high resolution of 16 bits (65.536 clock cycles per revolution). They also have a compact body, a measurement range in the single-turn version from 0 to 360 °, and 4096 revolutions in the multi-turn version. Depending on the interface, they offer a reset/restart button and an additional speed indicator. The design of the TWK-ELEKTRONIK optical encoder of the KRD series consists of a flange, an aluminum housing, a stainless steel shaft, ball bearings with an O-ring, an encoding disk made of glass or durable plastic, GaAIA diodes, a photo-transistor matrix with trigger circuits for long-term stabilization, a data bus for sensor systems.
