S	Standard	1.8 [51g/0.50N]	3.5 [99g/0.97N]	SS	1,000,000
B	High Preload	2.0 [57g/0.56N]	2.6 [74g/0.72N]	SS	1,000,000

Next: Choose applicable Options.

Select your option (if required).

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.

You may add your Part Number to your Order.

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].
