Overview
The PSENvip is a camera-based protection system for press brakes. It consists of a trans-
mitter and receiver, which are fixed to the moving part of the press brake, the upper die.
The detection zone between the transmitter and receiver monitors the immediate danger
zone below the moving upper tool.
The detection zone moves with the upper die, providing mobile safeguarding of the danger
zone. If an object encroaches into the detection zone, both output signal switching devices
(OSSD1, OSSD2) on the PSENvip will switch to the OFF-state. The safety system will use
these signals to initiate stopping of the press stroke.
