• Approved by EN, UL, CSA, and CCC (Chinese standard).
(Ask your OMRON representative for information on
approved models.)
• Sealing characteristics that meet IEC IP67 degree of
protection.
• Triple-sealed construction:
Plunger section sealed via nitrile rubber packing seal and
diaphragm; switch section sealed via nitrile rubber cap;
cable entrance sealed via encapsulating material.
• Cable lengths of 3 and 5 m available on standard models.
Models also available with UL and CSA-certified cables.
• Multiple mounting possible with Switches with Plungers.
• Models with red LED indicators added to series for easy
confirmation of operation.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
(Set by default to light for non-operation.)
• VCTF oil-resistant cables with CE marking.
(Applicable only to standard models.)
