A vision sensor with a 1,280 × 1,024 pixel imager makes possible highly detailed automated error-proofing and inspections. The P4 Edge 1.3 from Banner Engineering Corp., Minneapolis, (banner.com) is said to capture minute details of multiple features at ranges from a few inches to several feet, depending on its lens. The vision sensor performs up to 1,200 inspections per minute. A remote Teach function lets the sensor inspect new features without connecting to a PC or halting production. In addition, a built-in live video output lets users view the sensor's inspections in real time and see failed inspection images without a PC.
