The EU directive 2011/65/eu, (RoHS-2), in effect since 2011, restricts the use of 10 hazardous substances above a certain threshold level, when used in electrical and electronic equipment.
However a number of exemptions still allow the use of these hazardous substances. For the substance Cadmium (Cd) the use is allowed in electrical contacts. However this exemption to the restriction of Cd will expire on July 21, 2016. This means that from that date onwards, the use of Cd in relays is not allowed and therefore will not be available anymore.
Fujitsu Components has prepared several options to help design out the Cd containing relays and replace these by Cd free and RoHS compliant relay types. For the JS relays:
Change to existing and readily available Cd free types with AgSnO2 contact material, capable of 100k ops. on N.O. contact and 50k ops. on N.C. contact
Change to a new Cd free contact material type capable of 100k ops. on both the N.O. contact and N.C. contact in a sealed version.
Change to a new Cd free contact material type capable of 100k ops. on N.O. contact and 100k ops. on N.C. contact, open ventilated version.
Similar options will be available for other Cd containing relay types.
