Note: 1. The above values are initial values. 2. Once the contact is opened or closed with an ordinary load, it cannot be used for a load smaller than that. The contact surface may be rough, which impairs the reliability of contacting. *1. The degree of protection shown above is based on the test method specified in EN60947-5-1. Be sure to confirm in advance the sealing performance under the actual operating environment and conditions. *2. Durability values are calculated at an operating temperature of 5 to 35°C, and an operating humidity of 40% to 70%. Contact your OMRON sales...
