Relationship of Mounting Distance between K8DS-PU Relays and Ambient Temperature (Reference Values)
The following diagram shows the relationship between the mounting distances and the ambient temperature.
If the relay is used with an ambient temperature that exceeds these values, the temperature of the K8DS may rise and shorten the life of the internal components.
