Next-generation light curtains ‘set new standards’

01 May, 2013

Sick has announced a new generation of safety light curtains that, it says, set new standards for efficiency, ease-of-installation and reliability. The deTec4 Core curtains have no blind zones, offering optimum positioning and protection against unsafe access, while allowing operations to continue efficiently.

“We believe the deTec4 sets a new best-in-class benchmark for single-sided access protection,” says Sick’s UK safety specialist, Dr Martin Kidman. “The DeTec4 is very easy to install and commission, with an automatic range measurement of up to 10m. Once set up, it operates economically and reliably.

A space-saving design minimises safety distances. Various protective field heights are available in 150mm increments from 300mm to 2100mm, and there is a choice of finger (14mm) or hand (30mm) resolution to guard against operator intervention in accordance with EN ISO 13855. The system complies with Pl e, Type 4 and SIL 3.

Because the sensors work in protective mode only, configuration and range adjustment are automatic. Innovative mounting brackets, combined with LEDs, make alignment easy, allowing the curtains to be commissioned “in seconds”. Diagnostic codes are simple and additional functions can be set up via safety relays, or Sick’s Flexi Classic or Flexi Soft safety controllers.

The IP67-protected curtains have an operating temperature range from -300 to +550°C, allowing them to be used in demanding industrial environments.
