f plugs: zinc or brass?

PS I was looking at the CPC web site. Why is it that an adaptor that
has an f socket on one end and a coax socket on the other end is only
25 pence but to go from an f socket to a coax plug is over a pound? I
expected the plug option would be more popular considering that tvs
and recorders require a plug input but I suppose people use the right
plug rather than use an adaptor.

What doesn't help is that there is not one name for the plugs (and
sockets) that are traditionally used for televisions. On cpc I have
seen uhf, coax, and pal all used as different words for the same
thing.

Thanks,
Stephen.

CPC sell different ranges of the same types of connectors, at different
prices. Not all connectors are available in all ranges.

I thought the criticisms are about the poor connection between the
cable and the plug? If you have one where you solder or screw the wire
to the plug, are they really that bad?

What is wrong with DIN? Are you meaning the five pins in a semicircle
din?

That's the 180deg one. I've always (since I was a teenybopper) used them
for my 12V vehicle aux sockets and plugs. Never had a problem really. I
use the 270deg ones for 24V.

The big problem with most of them, in my experience, is that they pull
out far too easily. Also, they wobble, so if the cable moves around a
bit they gradually inch their way out.

Again, this is just my experience, and I can't say I've used every
single variant. But I can say that I had a customer return on an
electronic widget I made which used DINs, for that very reason.

The locking version gets round that problem. They're still a very flimsy
connnector, though. Introduced partly to save on space, and partly to
protect the European equipment makers' monopoly, IIRC.

For a start, any connector made of a plastic which melts easily when
soldering (if it is a solder only connector) is junk as far as I'm
concerned. The Belling Lee fits into this too. The standard DIN plug also
falls apart easily. You can get better designed ones, though.

Other thing with DIN is the plating on the pins seems to corrode easily -
even in a normal domestic environment - over the years resulting in a poor
connection. That - and other reasons - is probably why they've fallen out
of favour these days.

The Touchel version - same pin spacing but lockable and made of decent
materials is ok. But in a different league, price wise.

I use RS ones and I don't have problems with soldering or anything else.
They are very expensive though.
