Omron D4A-N DATASHEET

General-purpose Limit Switch

D4A-

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).

• Block mounting method to reduce weight to 290 g.

• Block mounting method also reduces downtime for mainte-

nance.

• Wide standard operating temperature range: –40°C to 100°C (standard type).

• Models with fluoro-rubber available for greater resistance to

chemicals.

• DPDT, double-break models available for complex operations.

D4A-1

Switches with fluoro-rubber seals (with an operating temperature range of –10°C to 120°C) may be ordered by adding an “F” suffix to the

model number. (Example: D4A-3101N-F for D4A-3101N) Contact your OMRON representative for details. Switches with silicon rubber seals that have high weather-proof performance are also available and may be ordered by adding an “T”

suffix to the model number. (Example: D4A-3112N-T for D4A-3112N) Contact your OMRON representative for details. Levers for Roller Lever Switches are optionally available. Select the lever from those listed in this datasheet (refer to

and 29) and order. “Roller lever: maintained” refers to actuators that possess a lock mechanism for switching operations. Use a Fork Lever Lock (D4A-E@@)

as the lever.
