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 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 inches [mm]. All spring forces in ounces [gms].
