Designed for loaded board testing.
QA Technology offers many combinations of probes. You can build your probe by selecting the tube style, tip style and spring force for your specific application.

|N||No probe lubrication. Removing probe lubrication greatly reduces cycle life and should only be used in applications requiring operating temperatures below -45°C or above 120°C.|
|Heat treated steel/plated gold over nickel. (see tip styles for availability).|
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.
