Camera-based measuring system

Automotive Design & Production, Dec, 2007

Pilz Automation Safety's (www.pilz.com) PSENvip measurement and protection system design for press brakes provides an easy-to-configure and low-maintenance camera-based way to reduce the reliance on curtain systems. It creates protected fields that are constantly monitored and represented on the camera unit's display, assuring that any object (finger-sized or smaller) breaching the protected area results in an immediate stop in less than 3 milliseconds. Suitable for press brakes up to 32.8-ft. long, the system uses an LED-based light source and camera unit complete with integral display. The camera is connected to either a PNOZmulti modular safety controller or a programmable safety system, both of which are mounted to the upper die to save space, while providing added resistance to vibration and interference from diffused light sources.
