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.
*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.
