Absolute rotary encoder with fieldbus interface
Wachendorff Automation GmbH & Co
WDGA, possess new, outstanding qualities thanks to their
patented EnDra technology:
* Free of wear - no gears
* Environmentally friendly - no battery
* High energy efficiency - low power consumption
With their high resolution of 12 Bit singleturn and 12 Bit 18 Bit
multiturn, they are ideal for those applications, where high measuring
accuracy as well as mechanical ruggedness is important. The
interface provides the evaluation electronics with the complete
position value, consisting of the combination of the singleturn
position with the corresponding multiturn position based on the
number of revolutions. The resolution of the singleturn position is
12 Bit (4096 steps per revolution). The multiturn can handle up to
40 bits, depending on requirements.
Despite its extremely high resolution, the maintenance-free encoder
has need of neither gears nor back-up battery. This guarantees
a long service-life for the mechanics as well as helping protect
the environment.
With its exceptionally high shaft loads of up to 220 N radial and
120 N axial, it will work reliably and accurately for years to come.
Quick in operation
The WDGA absolute encoders are equipped with a two-colour
LED (red/green). Thanks to the differentiated change in colour and
the varying blinking frequencies of the LED, important status
signalling can be read off directly
