Note: The above figures are initial values.
*1. Contact your OMRON sales representative for measurement conditions of the repeat accuracy.
*2. Durability 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.
*3. The value indicates the operating position change rate for a change of 1°C in the ambient temperature. The
       specifications depend on the model.
       Contact your OMRON sales representative for details.
*4. Values for contact output models.
