1595.0. "Material of RJ45 8 pins" by TKOV51::KATSUBE (Taiji Katsube) Thu Oct 20 1994 04:17

Can I ask a peculiar question?

My customer wants DECrepeater90T and then asked me about the material
of RJ45 8 pins. He is afraid of the corrosion.
It looks like gold-plated copper. Am I wrong?

	Thanks.

1595.1Re-assure the customer there should be no problem....NETCAD::BATTERSBYThu Oct 20 1994 12:2812
    Most connector contacts used in the computer industry are some kind 
    of alloy of beryllium (sp?) copper with degrees of gold plating.
    I personally don't think the customer should worry about the
    material or plating of the RJ45 contacts in the cable connectors
    or the mating connectors on the DECrepeater90T. They will work 
    just fine for a considerable length of time before he has to be
    concerned with corrosion. A lot of DEC standard environmental
    testing goes into our products over a wide range of temperature
    and humidity. Try temperatures of 5-50 degrees C and relative
    humidity of 10% to 95% (noncondensing).

If the customer has some unusual concerns due to deployment in a corrosive
environment (such as around seawater or chemical plant), they should probably be
worried about corrosion for the entire unit, not just the connectors. If that's
the case, they should consider some environmental protection.

    Steve you're absolutely correct. What isn't indicated in the base
    note is the specifics surrounding the why's for the customer expressing
    this concern. Our products are very much for the most part designed
    for an office & lab environment. The more that a customers environment
    approaches some kind of corrosive environment such as a chemical plant
    or something similar in nature, the more of a possibility of some
    detrimental effect to connectors and the products as a whole. Within the 
    presumed context of the customer's environment being of an office or 
    computer lab environment, there should be no concern about corrosion. 
    Other environments less benign should be mitigated where ever possible.
