Light curtain is intelligent

Typical applications include palletisers and de-palletisers, strapping machines, stretch wrappers and robotic and automated cells The new product overcomes the limitations of standard ‘muting’ light curtain safety guards. By using intelligent monitoring of broken beam patterns at hazard area entry and exit, the C4000 allows standard production flow while guarding personnel entry, thus minimising unnecessary and expensive downtime. The C4000’s intelligent beam monitor accurately distinguishes between production objects and people at all times, which eliminates the need for additional muting sensors and lamps. In this way, the new SICK light curtain avoids the common failings of standard guards including lamp or sensor failure, misalignment, poor installation and the possibility of manipulation by personnel. When an object breaks the light beams, the SICK C4000 intelligently assesses the broken beam pattern against previously input data. It allows standard sized and shaped pallet or skid-mounted objects to pass through, while instantly detecting the pattern made by a walking person, even if alongside the pallet.
