Safety light curtains

The first and last beams of the Banner Engineering EZ-Screen Low Profile (LP) safety light screens 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 is supplied in 14 or 25 mm resolution models, defined areas from 270 to 1810 mm and detection ranges up to 7 m with excess gain to solve a variety of application needs. The interconnection of cascade sensors allows up to four sensor pairs and an emergency stop or interlocking guard switches to be connected at the end sensor. There are also models with a nickel-plated housing for ESD-safe applications, a clear anodised aluminium housing or a ‘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 adapters for slotted and tubular framing, and fixed or pivoting angle brackets.

Blocked beams are identified using zone indicators, and a 7-segment display shows diagnostic information and the number of blocked beams.

The EZ-Screen LP offers response times as fast as 8 ms and exceeds OSHA/ANSI Control Reliability requirements, certified to cULus NIPF, and CE certified to Type 4, Category 4 PLe and SIL 3. Two solid-state safety outputs (500 mA each) are provided, including selectable trip/latch output, and there is a user-configurable auxiliary output at 250 mA.
