Z General-purpose Basic Switches are built into ZE, ZV,
and ZV2 Switches. They provided high durability and high
breaking capacity.
•
X Basic Switches with magnetic blowout are built into XE,
XV, and XV2 Switches. DC models have also been added
to the series.
•
Three mounting methods (side, base, and diagonal side)
and many types of actuator are available.
•
Terminals face the front when the cover is removed for
easy connection.
•
Switches with ground terminals have CE marking.
•
Approved by UL, CSA, and CCC (Chinese standard).
(Ask your OMRON representative for information on
approved models.)
Be sure to read
Safety Precautions
on page 8 to 9 and
Safety Precautions for All Limit Switches.
