3.0 RoHS Control And Monitoring In Panasonic

Panasonic voluntarily set corporate-wide internal limits exceeding RoHS legislation. This system not only requires declarations from suppliers but also analytical proof on a regular basis. Based on these results, Panasonic can assign risk levels to suppliers and products purchased, ensuring all products conform to the RoHS Directive and internal standards.

The RoHS directives are aimed at 10 categories of electrical and electronic equipment:

                    i.            large household appliances
                  ii.            small household appliances
                iii.            IT and telecommunications equipment
                iv.            consumer equipment
                  v.            lighting equipment
                vi.            electrical and electronic tools
              vii.            toys, leisure and sports equipment
            viii.           medical devices (with the exception of all implanted and infected products)
                ix.            monitoring and control instruments
                  x.            automatic dispensers

The RoHS directive is applied uniformly in Europe and bans lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) as hazardous substances from July 1, 2006 onwards.

Within the scope of this directive, categories viii and ix of the 10 categories listed above are excluded for the time being. This means, components are used in medical or industrial devices are not covered by the RoHS directive. When used in the other categories, e.g. household appliances, then compliance is required. As a result of this environmental policy, all Panasonic relays are now ROHS compliant.

Relays with contacts that contain cadmium are still exempt from the RoHS directive. However, due to its general corporate policy, Panasonic no longer offers any relays whose contacts contain cadmium. So besides Cadmium-free relays, Panasonic will keep relays with AgCdO contacts available upon the customer's request.
