General-purpose Limit Switch
D4A-@N
CSM_D4A-_N_DS_E_4_1
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.

2.Switches are also available with fluoro-rubber seals for higher resistance to chemicals. (The operating temperature range for these Switches, however, is −10 to +120°C.) Add “-F” to the model number. (Example: D4A-3101N becomes D4A-3101N-F.) Ask your nearest OMRON representative for details.
*1. The lever is not included with the Roller Level Models. Select the lever from those listed in this data sheet and order it separately (refer to Levers on page 12). *2. The Maintained Switches have a lock mechanism for the switch operation and thus use a Fork Lever Lock.

*1. Levers for Roller Lever Switches are optionally available. Select the lever from those listed in this data sheet and order (refer to Levers on page 12).
*2. The D4A-C00 adjustable roller lever is too heavy and long for these heads and it should not be used or mechanical malfunction will result.
*3. These heads cannot be used for double break operations.
