In-Sight 3900

Inspect more features, solve more applications, and achieve industry-leading accuracy with the In-Sight 3900 – a high-speed AI machine vision system built for high-throughput production lines. Powerful computing and embedded AI support high-resolution images and advanced inspections, while unified software and the industry’s largest set of vision tools enable flexible deployment and easy integration. 

Powered by UR g-Series and PolyScope X

UR g-Series robots deliver 24 V power and 1 Gb Ethernet directly at the tool flange. The In-Sight 3900 needs both, so mounted eye-in-hand it draws power and streams vision data straight down the arm, with no external supply and no separate camera cable. Powering and networking the camera at the flange keeps the cell cleaner and makes vision-guided, AI-enabled automation simpler to build.

PolyScope X completes the picture. A ready-to-use URCap brings inspection setup onto the teach pendant, so you Acquire, Inspect and Guide with results passed straight to the robot program, and the cell reaches production faster.
