End-to-end safety

4th Quarter 2009 Other technologies

New low-profile models of Banner Engineering Corp’s EZ-SCREEN family of safety light screens have been introduced. These are ideal for safeguarding smaller machines or even large power presses. The first and last beams of the new EZ-SCREEN Low Profile (LP) are positioned at the ends of the light screen, delivering continuous detection along the entire light screen length and eliminating the dead zones found on traditional safety light curtains.

The compact 28 x 26 mm housing design and end-to-end sensing of the LP screens overcome hazardous dead zones that can occur when traditional safety light curtains are positioned within the frame of the machine.

The LP screens’ outline specifications are:

Resolution: 14 or 25 mm.

Defined areas: from 270 to 1810 mm.

Detection ranges: up to 7 m.

Housing: nickel-plated for ESD-safe applications; clear anodised aluminium; or 'safety' yellow powder-coated.

Up to four sensor pairs and an Emergency Stop or interlocking guard switches can be connected at the end sensor.

The EZ-SCREEN LP offers simple alignment and setup, flexible wiring to allow emitters and receivers to be used interchangeably, easily configured reduced resolution, fixed blanking and cascading. Blocked beams are identified using zone indicators, and a 7-segment display shows diagnostic information and number of blocked beams.
