Note: 1. Switches are also available with []1/2-14 NPT conduits. The model numbers correspond as follows:
(Examples) G 1/2 Conduits 1/2-14 NPT Conduits
D4A-3[][][]N D4A-1[][][]N
D4A-4[][][]N D4A-2[][][]N
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. Not all combinations are possible. Ask your 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 Data Sheet).
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 Data Sheet).
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.
