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.

Note: Silicon rubber is used to increase resistance to the environment. Silicon rubber, however, can generate silicon gas. (This can occur at room temperature, but the
amount of silicon gas generated increases at higher temperatures.) Silicon gas will react as a result of arc energy and form silicon oxide (SiO
2
). If silicon oxide
accumulates on the contacts, contact interference can occur and can interfere with the device. Before using a Switch, test it under actual application conditions
(including the environment and operating frequency) to confirm that no problems will occur in actual.
