Product description
Technical data
•
Industrial standard housing Ø58 mm
•
13 Bit singleturn
•
Output code: Gray and binary
•
Short-circuit proof push-pull output
•
Inputs for selection of counting direction, LATCH and PRESET
•
Code change frequency up to 400 kHz
•
Servo or clamping flange
Singleturn absolute encoder
FVS58
The emphasis for this series is on rapid data transf er. Posit ion data are read directly out of the
Gray code disc. The high code switching f requency of 400 kHz is achieved by consciously
avoiding the use of a microcontroller.
In terms of the mechanics, designs with clamping flange or servo flange are available for the
FVS58 singleturn absolute encoder.
