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 outside of the working temperature range. See Testing in Extreme Working Temperature application note for more details.3

1 Current 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.

2 Maximum plunger OD should be used to calculate minimum guide plate clearance holes.

3 Working Temperature Range: -55°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 ounces [grams/Newtons].
