General-purpose Limit Switch
D4A-@N
The Limit Switch with Better Seal,
Shock Resistance, and Strength
A double seal on the head, a complete gasket cover, and
other features ensure a better seal (meets UL NEMA 3, 4,
4X, 6P, 12, 13).
Wide standard operating temperature range:
−40°C
to +100°C (standard type).
Models with fluoro-rubber available for greater resistance
to chemicals.
Block mounting method also reduces downtime for
maintenance.
DPDT, double-break models available for complex
operations.
Approved by UL, CSA, and CCC (Chinese standard).
(Ask your OMRON representative for information on
approved model.)
Be sure to read
Safety Precautions
on page 14 to 15 and
Safety Precautions for All Limit Switches.
