EEVblog #1052 - BEWARE Crap Banana Plugs!

(1/6) > >>

Dr. Frank:
These multi contact plugs - LS 4 - are really high grade.
Got them on stock and in use  for > 25 years, practically no wear-off of the gold plating, of course also no corrosion.
I measured 0.02 ohm for a 50cm mc cable. They also have low thermal voltage.
You get what you pay for.

These slits in these plugs  might pose some problems nowadays on DMMs, if they have a switch detector in their jacks.
Therefore, MC obviously prefers round, slotted plugs nowadays.

I have encountered similar problems in the past

CDN_Torsten:
I've had a similar problem - ordered a bunch of nickel plated ones.  They had the same intermittent contact as Dave shows in his video.  I didn't want to trash them, so I (very cleanly) soldered the tip-end of the spring.  They are now the best banana jacks I own.  ;D
