s reed relays and electronics india limited ? info@reed-switch.com ? tel 91-44-6528-4022 restriction of hazardous substances rohs compliance in late 2002 the european parliament approved two directives related to the reduction of electrical and electronic waste, namel y the waste electrical and electronic equipment (weee) and restriction of the use of certain hazardous substances (rohs) directives. the weee directive aims to regu late 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 eliminatio n of these substances from most electronic equipment starting 1 july 2006. our products are sgs certified for the rohs compliant le vels 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) regu lations 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 a pplied at the homogeneous material level. since rohs compliance is a stricter standa rd than elv compliance, parts that are rohs compliant are also elv compliant. due to continual improvement, specification s are subject to change without notice www.reed-sensor.com 20 january 2009
s reed relays and electronics india limited ? info@reed-switch.com ? tel 91-44-6528-4022 magnet sensor usage notes magnet sensors are delicate products. 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 dw ell. this may cause damage to the seals, change sensitivity, and reduce solderability. do not drop. dropping or subjection to shock will perman ently damage the contact or alter the sensitivity (at). switching voltage, switching current, and contact rating should not exceed maximum limits stated in specification sheets. due to continual improvement, specificati ons are subject to ch ange without notice www.reed-sensor.com 26 may 2004
