The principle of absolute encoder

    Schematic absolute encoder

    

    Is an absolute encoder having a plurality of transparent windows and opaque rotating disc, optical receiver is interrupted beam to collect the light pulses into electrical pulses, the output of the electronic processing circuit, and the electrical pulse sent.

Absolute encoder classification

    Single-turn absolute encoder

    Single-turn absolute encoder even in case of power failure, as long as the encoder shaft is rotated to an angle you can get an accurate displacement value, and each shift value can be accurately converted to a Gray code or binary code. Eltra single-turn encoder up to a maximum resolution of 8192 positions / revolution (13).

    Multi-turn absolute encoder

    Multi-turn absolute encoder EAM start character identified. It is a single-turn encoder extended range of applications. Class encoder single-turn resolution of up to 8192 position / rotation, while its multi-turn loop count of up to 4096, we can produce an elastic extension measurement accessories linear motion according to customer requirements. On the spindle attachment so that the encoder can be 'stacked' to install one or more of the speed reducer, so that the encoder at power-down, but also to ensure accurate readings. Eltra encoder resolution currently up to 25 which is equivalent to 33,553,432 number of positions. The encoder performance that is good and safe. Electrical Eltra multiturn encoder with a variety of selectable output mode and mechanical properties.
