1Current Rating is affected by spring material and lubrication choices. Standard lubrication has a 120°C maximum operating temperature limit. Use SS springs with no lubrication (-N) for testing beyond standard lubrication temperatures limits up to 204°C, Before using probes near these current limits, please refer to Current Carrying Capacity and Operating Temperature Application Notes.
All specifications subject to change without notice. All dimensions are in [mm]. All spring forces are oz [gm]. US Patent No. 4,885,533
