Letter Description
 B Curved tube (pylon replacement)
 N No probe lubrication. Removing probe lubrication greatly reduces cycle life and should only be used in applications requiring operating temperatures below -55°C.

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.

All specifications subject to change without notice. All dimensions are in inches [mm]. All spring forces in ounces [gms].
