The WEEE Directive aims to regulate the reuse, recycling and recovery of waste electrical and electronic equipment; the ultimate goal is to prevent the disposal of this waste. In the RoHS Directive, the use of the aforementioned substances in most electrical and electronic equipment will be banned or severely restricted. The RoHS Directive calls for the elimination of these substances from most electronic equipment starting 1 July 2006. Our products are SGS certified for the RoHS compliant levels of Lead, Mercury, Cadmium and Hexalent Chromium. End-of-Life Vehicle (ELV) End-of-Life Vehicle (ELV) regulations set limits for the following substances: Lead Mercury Cadmium Hexavalent Chromium Restriction of Hazardous Substances (RoHS) The Reduction of Hazardous Substances (RoHS) regulations set limits for the following substances: Lead Mercury Cadmium Hexavalent Chromium Polybrominated Biphenyls (PBB) Polybrominated Diphenyl Ethers (PBDE) To certify to the above compliances, these substances must not be intentionally added to the product AND cannot exceed the following maximum allowable levels as a trace substance: 0.1% (1,000 ppm) for: Lead*, Mercury, Hexavalent Chromium, PBB and PBDE 0.01% (100 ppm) for: Cadmium *Lead as an alloying element in copper alloys is allowed up to 4.0% (40,000 ppm); in steel up to 0.35% (3,500 ppm) is allowed; in aluminum alloys up to 0.40% (4,000 ppm) is allowed. These requirements must be applied at the homogeneous material level. Since RoHS compliance is a stricter standard than ELV compliance, parts that are RoHS compliant are also ELV compliant.

Handle with extra care. Do’s When switching inductive or capacitive loads, use contact protection circuits. Don’ts Do not use ferro-magnetic mounting parts, screws, or other ferro-magnetic devices nearby. This will affect the sensitivity (AT). When manual soldering, do not subject to more than a 5 second dwell. This may cause damage to the seals, change sensitivity, and reduce solderability. Do not drop. Dropping or subjection to shock will permanently damage the contact or alter the sensitivity (AT). Switching voltage, switching current, and contact rating should not exceed maximum limits stated in specification sheets.
