Note: 1. Models are available separately with resistance to viscous oils (oil drain holes are also available), but only with Plunger Models. Add -M to the model number
(example: D4C-1202 would be D4C-1202-M).
2. Switches with variable roller levers are also available. Ask your nearest OMRON representative for details.
*1. Oil-resistant vinyl cabtire cables; approved by EN and IEC.
*2. Ordinary vinyl cabtire cables;approved by EN and IEC.
*3. Switches with SJT(O) Cables (cables approved by UL and CSA) are approved by UL and CSA.
