N No probe lubrication. Removing probe lubrication greatly reduces cycle life and should only be used in applications requiring operating temperatures below -55°C.

S Heat treated steel/plated gold over nickel (see tip style for availability)(Blank) No option required

1 Current Rating is affected by spring material and lubrication choices. Standard lubrication has a 120˚C maximum operating temperature limit. Use SS springs with no lubrication (-N) for testing beyond standard lubrication temperature limits up to 204°C. Before using probes near these current limits, please refer to Current Carrying Capacity and Operating Temperature Application Notes.

2 Maximum plunger OD should be used to calculate minimum guide plate clearance holes.
