Note:

1. The above figures are initial values.

2. The figures in parentheses for dielectric strength, are those for the overtravel (high-sensitivity) model.

3. Life expectancy values are calculated at an operating temperature of 5°Cto 35°C, and an operating humidity of 40% to 70%. Con-

tact your OMRON sales representative for more detailed information on other operating environments.

4. 10,000,000 operations min. for general, high-sensitivity, and flexible rod overtravel models.

5. 500,000 operations min. for high-precision and outdoor specifications models. All microload models however, are 1,000,000 opera-

tions min.

6. Except the flexible rod models.

7. For low temperature models this is --40_Cto40°C (no icing). For heat-resistive models the range is +5°C to 120°C.
