2. The figures in parentheses for dielectric strength are those for the high-
sensitivity 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.
Note: As an example, AC-15: 2 A/250 V means the following:
Application category

*2. Durability is 10,000,000 operations min. for general-purpose or high-
sensitivity overtravel models.
*3. Durability is 500,000 operations min. for high-precision models. All
microload models however, are 1,000,000 operations min.
