SICK (UK) product story

SICK's Minitwin 4 light curtain application, combines sender and receiver elements in a single miniature housing, enabling continuous 'end-to-end' field coverage without blind spots.
The modular Minitwin 4 units are 120-1200mm long and can be cascaded or daisy chained end to end to 3600mm without any blind spots.
Rapid response times permit safety monitoring with reduced reach distances for operators and smaller machine footprints.
Field coverage is continuous between adjacent units without loss of resolution or requiring special mountings or physical protection between curtains.
The Minitwin 4 units may be configured to protect L-, V- or U-shapes, combining easy access to a work piece or to change tool bits or jigs, while offering complete protection.
They are suitable where all-round accessibility and visibility is required which is otherwise restricted by fixed barriers.
Variable field lengths are possible to suit locations.
Each unit includes send and receive functions and the inbuilt controls and LED-status indication means that any two identical units operate as light curtain, without need for an extra control unit, allowing spares to be stocked as single units rather than in send/receive pairs.
The Minitwin 4's range is available up to 4m, 15 x 32mm cross-section and in a choice of three object resolutions from 14 to 34mm.
Configuration and alignment tools are automatic and built in, with full status and diagnostic LED displays.
The universal fixing brackets ensure rapid secure installation, for instance to standard aluminium profile, and the rotating connector with standard M12 5-pin plug will accommodate any orientation.
The Minitwin 4 is designed to meet performance level pl 'e', according to BS EN13849-1, SIL3 in compliance with IEC 61508, or the sector standard BS EN62061.
