Reliable Electrical Quick Connections for High-Data Rate Video Signals

Robot Embedded Vision Application - Tool Changer PES

Industrial vision applications have been increasingly introduced in factories for the last past years.

Object recognition applications enhancing automated verification tasks are now common industrial tools and there are still new applications for those cameras. Those are now sufficiently robust and compact to be embedded on robot End-of-Arm. In this specific case, they are often used to measure or correct the robot path dynamically.


When using a tool changer with tools that embed such cameras, the major challenge is to transfer the high data rate video signal through the tool changer quick connection.

From standard 100Base-TX Ethernet to GigE Vision application, PES always provides the proper electrical interface to meet the communication standard requirement.

Sometimes we also integrate contact redundancy for increased availability of the video link.

All of our Fieldbus or vision interfaces are certified regarding the corresponding communication standard. Obviously, this video link can be embedded on the tool changer as well as other electrical or fluid interfaces to support other tools functions.
