OMRON D4A-N Series Product information and technical parameters:
Brand: OMRON
Name: General-purpose Limit Switch
Model: D4A-N Series
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.)
