High Temperature Beryllium Nickel Contacts

Mill-Max now offers nine contacts made from Beryllium Nickel Alloy 360 (UNS N03360.) Contacts made from Beryllium Nickel are recommended for receptacle applications where the Operating Temperature exceeds 150°C. Some common applications for these contacts are found in: the oil industry for down-hole wells and exploration; "Test & Burn-in" sockets for stress testing electronic devices (i.e. chips); high temperature commercial lighting fixtures (e.g. Halogen lamps) and Autoclave sterilization for the medical industry.

The table below shows the accepting lead diameter range for each contact and which standard contact clip it can be interchanged with.
