Frame light barriers
Frame light barriers from Dietz form a gapless infrared light curtain using numerous transmitter and receiver diodes in the opposing arms. Even the smallest parts can be detected optimally in the middle of the frame independent from the material, the surface or the colour of the object.
Easy installation, short response time and a very high resolution are the crucial advantages compared to conventional techniques using many single through-beam light barriers. A mutual interference of the beam pathes is ruled out. In tight spaces, the frame light barriers can operate also in the open U-shape when the traverse is removed. An integrated sensivity adjustment, a variable impulse lengthening and a high immunity to ambient light due to modulated light guarantee a secure processing of the output signal.
