First encoder configurable by Near Field Communication

04 May 2022

The new WDGN series of incremental encoders from Wachendorff Automation enables configuration of any pulse count from 1 I/U to 16,384 I/U via Near Field Communication (NFC).

Depending on the equipment, basic or advanced, additional parameters can be set via an app using NFC.
After downloading the Wachendorff WDGN app to the smartphone, the desired parameters and values can be configured without contact or voltage, and if necessary through the outer packaging.

Encoder configurations created can be saved under different names, reloaded at any time and transferred to another encoder. This means that saved configuration sets can be used for the encoder in different applications. The configuration set of an encoder can be read out, saved, shared and reused for other encoders at any time after entering the PIN. The PIN and PUK principle is used for security.

In the development phase, when there is uncertainty about which number of pulses the encoder needs to run optimally in an application, the WDGN encoder offers the necessary flexibility to test the optimum number of pulses. As soon as the optimum configuration has been found, the user receives an encoder with the same technological features for use in series production — but without an NFC antenna for cost reasons. A second qualification is no longer necessary.

This approach optimizes logistics and warehouse management, eliminating the potential for an encoder to be sent with an incorrect pulse count. With the free app on the smartphone, communication with the encoder takes place via NFC, completely without an internet connection, and the desired parameter values can be set just-in-time by the recipient.

In the application, the WDGN encoders offer a very high resolution of up to 16,384 I/U in a very compact design from 36 mm. This means that high-precision measurements can be realized in the smallest installation space.
