RELAYS Panasonic

| Kategorie: Katalog  | Tento dokument chci!

Panasonic is part of a large worldwide groupselling relays and associated switching products under different brand names in different territories.The conditions of use in some territories may differ from those customary in Europe. In particular there are often major differences in regard to national and international specifications, such as UL, CSA, VDE, SEV, EVE, SEMKO, etc. Thus, when considering contact loads as stated in this catalogue (e.g. 10 A, 30 VDC for the SP relay) its hould be understood that these values are not necessarily an absolute maximum but tested ratings. Mostly the stated value has been tested for a certain life expectancy as stated by the manufacturer or the respective test house. Thus, under different conditions, the stated “maximum” may, in practice, be safely exceeded.

tin y r u u • Avoid bending the term inals make the relay self-clinching. • Use rosin-based non-corrosive flux. Therefore, the following precautions are provided for soldering relay onto board. • Stick packaging also available for autom atic mounting, depending the type relay.) Interference may occur internally the gripping force the tab of the surface mounting machine too great. Never use this method. Solderability also improves.

Self-clinching term inal types are available depending on the type relay.Relay Soldering and Cleaning Guidelines RELAY SOLDERING AND CLEANING GUIDELINES In keeping with making devices compact, it becoming more common weld the relay board along with the sem iconductors instead using the previous plug-in type which relays were plugged into sockets. • the board pressed down into a flux-soaked sponge shown the right, the flux can easily penetrate a dust-cover type relay. • Correctly drill the board according to the given board pattern illustration.V4J Bad example 3 tin g r U U n 7 Be sure preheat before using autom atic soldering. Soldering Iron 30W 60W Iron Tip Temperature 350°C 662°F Soldering Time Within approx. Solder temperature 260°C±5°C 500°F±41°F Soldering time Within approx. For dust-cover type relays and flux-resistant type relays, preheating acts prevent the penetration flux into the relay when soldering. This must observed especially for dust-cover type relays. due a malfunctioning unit) may affect relay characteristics. ( \ Bad example 2 lic tio n • Adjust the position the board so that flux does not overflow onto the top of it. Unless otherwise specified, solder under the following conditions depending the type relay. Adjust the level solder that does not overflow onto the top the PC board. The type protective structure will determine suitability for automatic soldering autom atic cleaning. Temperature 120°C 248°F less Time Within approx.g. This could impair relay performance. Please review the parts construction and characteristics. See “Configuration and Construction” page 1. 1. 4 g A tic g Flow solder the optim method for soldering. • Preheat according the following conditions. (Be sure that the relays don't rattle. Relay performance may degrade due the high thermal capacity these boards. seconds Please take caution with ulti-layer boards. Please refer them during installation in order avoid problems. Note that the board is pressed down hard enough, flux may even penetrate flux-resistant type relay. ith this style, loss function may occur because of seepage into the relay flux, which is applied the board. • g Keep the tip the soldering iron clean
