Approved standards: UL, CSA.
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 D4N-4A22 PDF datasheet.
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.) Lock method: Solenoid lock.
Conduit size: G1/2.
Voltage for solenoid: 24 VDC.
Without indicator 1NC/1NO+ 1NC (Slow-action).
Release Protective Cover Locks Using.
Controller Signals or Pushbutton.
Switches after the Cutting Tool Stops.
Moving Due to Inertia.
A mechanical lock is applied automatically when the Operation.
Key is inserted. A high level of safety is achieved using a,
mechanism where the lock is only released when voltage is,
applied to the solenoid.
Conforms to EN (TÜV) standards corresponding to the CE marking.
Certified by UL, CSA and CCC standards.
The Switch contact is opened by a direct opening mechanism,
(NC contacts only) when the protective cover is opened.
Direct opening mechanism that is EN-certified is indicated by,
on the Switch.
Auxiliary release key ensures easy maintenance and unlocks the,
door in the case of a power failure.
Tough aluminum die-cast body incorporating a switch box with,

degree of protection satisfying IP67, UL, and CSA TYPE6P, 13 D4N-4A22 PDF catalog.
Equipped with a horizontal and vertical conduit opening.
Models incorporating easy-to-see indicators for monitoring and,
those using an adjustable Operation Key ffor a swinging door are available D4N-4A22 PDF catalog.
The mounting direction of the head can be changed,
to allow the Operation Key to be inserted from four directions.
