Contrinex AG and PocketCodr SA developed the PocketCodr and its companion app as digital tools for configuring IO-Link-enabled Smart Sensors. The PocketCodr is a rechargeable hand-held device that acts as an interface between the sensor (which is connected via a cable) and the app (which communicates with the PocketCodr via Bluetooth®).

The free PocketCodr app can be downloaded from Google Play or the Apple App Store and installed on Bluetooth®-enabled mobile devices running Android or iOS. It features several standard routines for IO-Link configuration; these are accessed using software controls called Action Widgets. The Home screen of the PocketCodr app features multiple Action Widgets, each of which has a dedicated function, guiding the user through a specific part of the configuration process.

Use of the PocketCodr device and app is MANDATORY for configuration and set-up of Smart Double-Sheet (IDSN) Sensors. IDSN sensors reject IO-link configurations that have not been validated by the PocketCodr app’s dedicated “double sheet teach” action widget.

The dedicated “double sheet teach” action widget is only enabled for PocketCodr user accounts with the “Application” plan subscribed. This subscription can be ordered directly from Contrinex SA.



IO-Link configurations contain multiple critical parameters that optimize an IDSN sensor’s measurement capability for a specific target material and thickness. PocketCodr’s ‘Double Sheet Teach’ routine enables users to determine and upload parametric values empirically, creating customized configuration profiles for their own unique applications.

Contrinex AG maintains a library of predetermined double-sheet-detection configuration profiles for various target materials and sheet thicknesses. A list of library profiles is available in the document “IDSN-MxxMM-NMS-A0 Operating Manual”.
