1Current Rating is affected by spring material and lubrication choices. Standard lubrication has a 204°C maximum operating temperature limit.
Before using probes near these current limits, please refer to Current Carrying Capacity and Operating Temperature Application Notes.
2Maximum plunger OD should be used to calculate minimum guide plate clearance holes.
