Ratings
Screw Terminals
Note: 1. The above figures are for steady-state currents.
2. Inductive loads have a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).
3. A lamp load has an inrush current of 10 times the steady-state current.
4. A motor load has an inrush current of 6 times the steady-state current.
* Refer to the rating of a General-purpose / Weather-proof Switches type for the rating of a high-sensitivity overtravel type.
* For high-sensitivity switches.
Characteristics
Note: 1. The above figures are initial values.
2. The figures in parentheses for dielectric strength are those for the highsensitivity overtravel models.
*1. The values are calculated at an operating temperature of +5°C to +35°C and an operating humidity of 40% to 70% RH. Contact your OMRON
sales representative for more detailed information on other operating environments.
*2. Durability is 10,000,000 operations min. for high-sensitivity models.
*3. Durability is 500,000 operations min. for high-sensitivity models.
500,000 operations min. for weather-proof models.
Contact your OMRON representative for information on Airtight Switches.
*4. Switches with Connectors: 1,500 V.
