Pushing the boundaries of light curtain safety
SICK has launched its new miniTwin 4 light safety curtain that combines sender and receiver elements in a single miniature housing. The miniTwin 4 also achieves continuous end to end field coverage with no blind spots.
The miniTwin 4 units are 120mm - 1,200mm long and can be cascaded or daisy chained end to end to 3,600mm without any blind spots. Rapid response times permit safety monitoring with reduced reach distances for operators and therefore, smaller machine footprints. Field coverage is continuous between adjacent units without loss of resolution or requiring special mountings or physical protection between curtains.
The units may be configured to protect L-shapes, V-shapes or even U-shapes and are suitable for when all round accessibility and visibility is required which is otherwise restricted by fixed barriers. Variable field lengths are possible to suit locations.
Each miniTwin 4 unit includes both send and receive functions and the in-built controls and LED status indication means any two identical units operate as light curtains, without any requirement for an extra control unit.
The miniTwin 4 is designed to meet performance level pl ‘e’according to BS EN13849-1, or alternatively SIL3 in compliance with IEC 61508 or the sector standard BS EN62061.
