Note: 1. The above values are initial values.
2. The above values may vary depending on the model. Consult your OMRON sales representative for details.
*1. The degree of protection is tested using the method specified by the standard (EN60947-5-1). Confirm that sealing properties are sufficient for
the operating conditions and environment beforehand.
*2. The durability is for an ambient temperature of 5 to 35°C and ambient humidity of 40% to 70%. For further conditions, consult your OMRON
sales representative.
*3. –20 to 80°C for the flexible-rod type.
*4. The above values may vary depending on switching frequency, environmental condition, and relativity level, consult your OMRON sales
representative.
