Safety light curtain protects against low level risk

Paul Boughton

Banner Engineering Corporation is introducing the EZ-Screen Type 2 light screen system that is designed for lower risk Type 2 applications (in accordance with IEC 61496-1 and 2, and Category 2 of EN 954-1).

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 30mm resolution, a hand or ankle is safely detected across long spans up to 15m.

“The EZ-Screen Type 2 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,” says Mike Carlson, technical manager for Banner's safety products.

EZ-Screen Type 2 systems provide reliable, effective and economical machine safeguarding. Appropriate application examples for a Type 2 system include the following: small assembly equipment; table-top robotic work cells; pick-and-place machines; small packaging machines; equipment and process protection
(non-personnel safety); and 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; and latch output model requires a manual reset once an interrupted beam is cleared.

The EZ-Screen Type 2 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 eight-pin Euro-style cables, which are available in 5, 8, 15, 23, and 30m lengths.
