Yes, like 3.5mm jacks, 5 pin DINs are only fit for limited use. Gold doesn't really solve that though. If you use something suitable like phonos or 1/4" jacks there's no real upside to gold unless the environment is corrosive. NT |

Tuchel do a connector with the same pin size and spacing as DIN - but more usually found on pro gear. And that has a better plating to the contacts and seems to be pretty reliable. I dunno what they use on the ordinary cheap DIN connectors - but I've seen several heavily corroded. Not something you seem to find often on other types of connector. -- *Why is the third hand on the watch called a second hand? Dave Plowman London SW To e-mail, change noise into sound. |

Which most of them aren't. it's entirely useless unless you're using the lead in a damp location No, gold connectors avoid tarnishing where others would, even in quite benign conditions and that is useful with low level signals. it's only useful if your connectors have an otherwise inadequate mating surface area. Much of industry only purchases industrial relays with gold contacts for control systems (even inside indoor control panels) - silver are fine for higher voltages and currents. SteveW a very different situation to signal connectors NT |

Most gold plating is a very thin layer, where the metal below has a habit of migrating through the gold and then leading to an oxide layer. Better than nothing though. |

So a good quality lead should have a reasonable thick gold layer but I;ve no idea how much extar such a lead would cost but I wouldn't have thought more than a couple of quid worth of gold. |
