General-purpose Limit Switch D4A-[]N

• 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.)

* For those with indicators, refer to the following rated voltages.

 

Item Type SPDT, Double-break DPDT, Double-break
Without indicator With indi-cator Without indicator With in-dicator
Inrush current Normally closed 30 A max.
Normally open 20 A max.

 

 

Note: 1. The above current ratings are for steady-state current.
2. Inductive loads have a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).
3. Lamp loads have an inrush current of 10 times the steady-state current.
4. Motor loads have an inrush current of 6 times the steady-state current.
