●Relationship of Mounting Distance between K8AK-PW 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 K8AK may rise and shorten the life of the internal components.
