SICK is extending the benefits of its Minitwin light curtain technology to a wider audience with the launch of the Minitwin 2, a cost-effective solution that meets level ‘d’/SIL2 safety requirements.

The Minitwin 2 incorporates sender and receiver elements in a single miniature housing for continuous end-to-end field coverage.

The modular units are 120-1,200mm 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 Minitwin 2 units may be configured to protect L-, V- or U-shapes, combining easy access to a workpiece or to change tool bits or jigs, while offering complete protection.

They are ideal where all-round accessibility and visibility – which is otherwise restricted by fixed barriers – is required.

Variable field lengths are possible to suit locations.

Each Minitwin 2 unit includes send and receive functions, and the inbuilt controls and LED status indication mean that any two identical units operate as a light curtain, without any requirement for an extra control unit.

This allows spares to be stocked as single units rather than in send/receive pairs.

The Minitwin 2 offers a range up to 4m, 15 x 32mm cross-section and a choice of three object resolutions, from 14 to 34mm.

Configuration and alignment tools of the Minitwin 2 are automatic and built-in, with full status and diagnostic LED displays.

The universal fixing brackets ensure rapid secure installation and the rotating connector, with standard M12 5-pin plug, will accommodate any orientation.

The Minitwin 2 is designed to meet performance level pl ‘d’ according to BS EN13849-1 or, alternatively, SIL2 in compliance with IEC 61508 or the sector standard BS EN62061.
