What is LEMO's position in regards to the requirements of RoHS (Restriction of Hazardous Substances) legislation?
LEMO Connectors and Accessories
LEMO certifies that its connectors and accessories marketed, manufactured, and shipped after January 1, 2006 are in full compliance with the requirements of Directive 2002/95/EC of the European Parliament and of the Council dated 27th January 2003 regarding the presence of: mercury, cadmium, lead, hexavalent chromium, polybromide biphenyl (PBB) or polybromide diphenyl ether (PBDE), including DecaBDE.
The Directive (EU Directive 2002/95/EC) specifies restriction of the use of certain hazardous substances in electrical and electronic equipment by July 1, 2006 and is known as the RoHS Directive
All part numbers will remain unchanged. The vast majority of all LEMO products require no adjustment for RoHS compliance. The few items that have internal solder connections have moved to lead-free solder. There are a few connectors with an optional aluminum-alloy shell that contains lead in that alloy. For that shell option LEMO will switch to a RoHS compliant aluminum alloy by January 1, 2006.
Contacts Designed for Solder Connection
All LEMO connectors with solder-style contacts are fully compatible with lead-free solder and the required higher temperatures. LEMO insulators are made of high temperature material and the standard connecting surfaces are made of an Au/Ni plating. In addition, LEMO has conducted verification testing of contacts and cable assemblies with lead-free solder.

Cable and Product Assemblies by LEMO
Standard cable and product assemblies from LEMO use lead-free solder. Cable assemblies and other value added products that require RoHS declarations of compliance will be available by June 1, 2006. Call us if you need help with certification earlier. LEMO also continues to offer custom services to meet customer specific requirements for both material and process (such as with solder selection) in cable and other product assemblies. Lead based or lead-free soldering processes are available.

All LEMO connectors are tested to MIL standard test requirements (see table below).
LEMO's F Series connectors meet or exceed performance requirements of military standards but are not "MIL-SPEC" connectors.
Examples of LEMO's B and F series testing include:
