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.

³P tube has Ø.016 [0.41] hold in end for identification only.

All specifications subject to change without notice. All dimensions are in [mm]. All spring forces are oz [gm/newtons].
