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.

The type protective structure will determine suitability for automatic soldering autom atic cleaning. Relay perform ance cannot guaranteed if the term inals are bent. • Preheat according the following conditions. See “Configuration and Construction” page 1. due a malfunctioning unit) may affect relay characteristics. • Use rosin-based non-corrosive flux. This could impair relay performance. Please review the parts construction and characteristics. ^ . 4 g A tic g Flow solder the optim method for soldering. (Be sure that the relays don't rattle. Adjust the level solder that does not overflow onto the top the PC board. • Stick packaging also available for autom atic mounting, depending the type relay.

Note that the board is pressed down hard enough, flux may even penetrate flux-resistant type relay. Relay performance may degrade due the high thermal capacity these boards. • the board pressed down into a flux-soaked sponge shown the right, the flux can easily penetrate a dust-cover type relay.) Interference may occur internally the gripping force the tab of the surface mounting machine too great. Self-clinching term inal types are available depending on the type relay. seconds ds_x61_en_relay_technical_information_091112D 31 . Solderability also improves. This must observed especially for dust-cover type relays. ith this style, loss function may occur because of seepage into the relay flux, which is applied the board.

For dust-cover type relays and flux-resistant type relays, preheating acts prevent the penetration flux into the relay when soldering.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. Please refer them during installation in order avoid problems. Unless otherwise specified, solder under the following conditions depending the type relay. • Correctly drill the board according to the given board pattern illustration. Never use this method.g. minutes • Note that long exposure high tem peratures (e. seconds Please take caution with ulti-layer boards. • g Keep the tip the soldering iron clean. Therefore, the following precautions are provided for soldering relay onto board. Solder temperature 260°C±5°C 500°F±41°F Soldering time Within approx
