Low-profile safety light screen

November 2009 Sensors & Transducers

Banner Engineering has expanded its EZ-SCREEN family of safety light screens to include low-profile models, which pair a space-saving footprint—ideal for safeguarding of smaller machines—with reliable performance. 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, thereby eliminating dead zones.

The EZ-SCREEN LP offers exceptional versatility with 14 or 25 mm resolution models, defined areas from 270 to 1810 mm and detection ranges up to 7 m with excellent excess gain to solve a variety of application needs. The interconnection of cascade sensors has also been optimised with no big cable loops, allowing up to four sensor pairs and an Emergency Stop or interlocking guard switches to be connected at the end sensor.

The low profile screen offers high performance and convenient features, including simple alignment and setup, flexible wiring to allow emitters and receivers to be used interchangeably, easily configured reduced resolution and fixed blanking and cascading. Blocked beams are identified using zone indicators, and a 7-segment display shows diagnostic information and number of blocked beams.

Reliable safeguarding is delivered in a wide range of applications, including:

* Small assembly equipment.

* Pick-and-place machines.

* Power and moulding presses.

* Palletisers and packaging machinery.

* Roll formers.

* Automated production equipment.
