Reer EOS4


[button text=”Download PDF” link=”” style=”default” size=”normal” target=”_blank”]

Compact, Type 4 – SIL 3 and SILCL 3 – PL e Light Curtain.
EOS4, with its small-size housing and minimum dead zone, is ideal for the protection of any tool machine, in particular where space restrictions exist.

Its very small dead zone, only present on one side, allows EOS4 to keep its resolution up to 30 mm if installed on a plan and up to 40 mm if installed at 90° against another EOS unit.

EOS4 is available in the X and XHversions, with the integration of start-restart interlock and external contactor monitoring (EDM), as well as in the A and AH versions with automatic restart.

Special versions with IP 69K watertight enclosure (WTF and WTHF), also suitable for Food & Beverage industry, available.
