Tube Material

Letter	Material	Average Resistance
G	Nickel silver/ID OD gold plated	< 15 mOhms

Select your tip style. Standard material is heat-treated BeCu/plated gold over nickel.
Use the drop-down menu at right to filter your choices by target type.

Spring Force

Letter	Spring Force	Preload	0.107 [2.72] Stroke	Material	Cycle Life @ 0.107 [2.72] Stroke
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

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 choice. MW springs and lubrication both have a 120°C operating temperature limit. Use SS springs with no lubrication (-N) for testing up to 204°C. Before using probes near these 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].
