Compact safety light curtains and grids

May 2017 IS & Ex

In applications with dangerous areas requiring finger, hand and operator protection, the small and powerful safety light curtains and light grids from ifm are a good choice.

The main differences of the versions from the OY series are the resolution and the protected area height. Various functions such as range and restart are configured directly on the unit, no PC required. A t-slot on the back allows simple and reliable mounting using the supplied mounting material. The various accessories make low-cost and efficient use easier.

The OY type curtain comes in a compact housing and can be installed without dead band. Selectable ranges are available from up to 20 m for light curtains and up to 60 m for light grids with easy tried-and-tested M12 connection.


Hand and finger protection: for light curtains type OYxxxS, an effective protection is reached by the small distances between light beams starting with 14 mm. Typical applications are presses, pick-and-place machines or handling machines. For hygienic areas, versions with protection rating IP 69K are required.

Blanking: blanking suppresses individual light beams or up to three neighbouring light beams. Floating blanking even allows different beams to be suppressed.

Muting: the temporary automatic muting function allows feeding or products to the dangerous area. Part numbers: OYxxxS; muting relay: G2001S

Safety in hygienic material resistance in cleaning processes with steam and high-pressure cleaners is reached by the enclosure of the safety light grid in a protective tube IP 69K with integrated heating protection against fogging. Part number: OY4xxS.
