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.

Note: 1. The above figures are initial values.
2. The figures in parentheses for dielectric strength are those for the microload 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 general-purpose overtravel models, and for flexible rod models. 500,000 operations min. for weather-proof models.
*3. Microload models are 1,000,000 operations min. 500,000 operations min. for weather-proof models.
*4. Except flexible rod models. The shock resistance (malfunction) for microload models is 200 m/s2 max.
*5. For low-temperature models this is –40°C to +40°C (with no icing). For heatresistant models the range is +5°C to +120°C.
*6. For microload models, the contact resistance is 50 mΩ max. (initial value for built-in switch)
