|L||Long plunger. Must select from X31-40 tip styles|
|N||No probe lubrication. Removing probe lubrication greatly reduces cycle life and should only be used in applications outside of the working temperature range. See Testing in Extreme Working Temperature application note for more details. 3|
|Heat treated steel/plated gold over nickel. (see tip styles for availability).|
1 Current Rating is affected by spring material and lubrication choice. Please refer to Current Carrying Capacity and Testing in Extreme Temperature application notes for more details.
2 Maximum plunger OD should be used to calculate minimum guide plate clearance holes.
3 Working Temperature Range: -45°C to 120°C with lubrication. SS springs can be used up to 204°C without lubrication.
All specifications subject to change without notice. All dimensions are in [mm].All spring forces are oz [gm/newtons]. US Patent No. 6,570,399 & 4,885,533
