Safety light screen
August 19, 2009 By Manufacturing AUTOMATION
Banner Engineering Corp. 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 suited even for 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 EZ-SCREEN LP offers exceptional versatility with 14 or 25-mm-resolution models, defined areas from 270 to 1,810 mm and detection ranges up to 7 m. The interconnection of cascade sensors has also been optimized 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. Also, there are models with nickel-plated housing for ESD-safe applications, clear anodized aluminum housing or “safety” yellow powder-coat housing.
The mounting scheme includes brackets for end or side mounting with no dead zone, both styles included with each sensor. Additional mounting options include a “Universal” adapter bracket for mounting to slotted framing, a solution for mounting the sensor inside tubular framing such as P1000 UnistrutÂ®, and fixed or pivoting angle brackets to make installation of cascade sensors quick and easy.
The EZ-SCREEN LP offers the high performance and convenient features expected of EZ-SCREEN safety light screens, 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.
