Hi everyone,
I’m purchasing this connector in the HDD series 1651150000 (male) and 1651160000 (female), and its accompanying accessories (see link below) namely:

  1. Crimp contacts (surface gold)
    Ques: which single contacts conductor mm2 should I choose, out of the given choices, as in what does those different sizes represent?

  2. Hood, cable entry sideways on pg B.67
    I’ve determined that we need the M20 w/thread version, but what’s the difference between the first 2 items as every spec is the same except for the Order No. which one shld I order?

Please advise,
Eddie

Hello Eddie,

Welcome to the DigiKey TechForum.
With contacts, the mm2 is a size for the wire, like the awg size. Looking for the gold contact, I do not see any referencing a mm2 size, only awg.
Click here for the listed male contacts.
Same for contacts for the other connector. Click here for the socket contacts.
I’m only seeing 1 hood with M20 threads on the size, which is 281-4783-ND (1788100000).
Comparing the 1788100000 and the 1805930000,… 1788100000 is an Active part, and 180593000 is Obsolete.
