Banner Engineering has introduced its EZ-Screen Type 2 light screen system designed for lower risk Type 2 applications (per IEC61496-1/-2, Category 2 per EN954-1). Lower risk applications are those which will not cause serious bodily harm. The danger is limited to minor, normally reversible injuries including bumping, bruising, knock down, trapping but not crushing, and superficial cuts and abrasions. With its 30 mm resolution, a hand or ankle is safely detected across long spans up to 15 m.
The device expands Banner's offering of Type 4 safety light screens, grids, and points into applications that require reliable operator safeguarding without the added expense of a Type 4/Category 4 system. Banner says that the product sells at 30% less than comparative alternatives.
Applications would involve effective and economical machine safeguarding. Appropriate application examples for a Type 2 system include the following:
* Small assembly equipment.
* Tabletop robotic work cells.
* Pick-and-place machines.
* Small packaging machines.
* Equipment and process protection (non-personnel safety).
* Supplemental safeguarding.
Several attributes of the EZ-Screen Type 2 make them easy to install and use:
* Intuitive, visible status LEDs indicate power on, fault (flashing LED), beam alignment (top and bottom) and beam/output status (blocked or clear).
* Trip output model automatically resets when an interrupted beam is cleared.
* Latch output model requires a manual reset once an interrupted beam is cleared.
Specifications: The device is a compact, two-piece system that is independently powered and optically synchronised. It does not require a separate control box, only a self-contained emitter and receiver pair. Dedicated trip or latch models eliminate the need for configuring or programming. A system requires standard 8-pin Euro-style cables, which are available in 5 m, 8 m, 15 m, 23 m, and 30 m lengths. As an optional hookup, splitters (Y-cables) can be used to further simplify hookup by providing a single 'homerun' cable and the ability to interchange emitter and receiver position without rewiring (ie, 'swapability').
