wtb 2,5/6 Plugs

[Roger Lascelles]

My W&G Level Generator and Receiver have coaxial sockets described as
"2,5/6" . A very kind person has provided some plugs, but I still need two
more. Any help greatly appreciated.

thanks
Roger

** Sure it s not a PL 259 you are after ???

Nothing I tried involving 256 gets any relevant hits on Google.

** Late news extra:

There is one called a 1.6 /5.6 - Farnell have them for $23 each + .


BTW Are the numbers the ID and OD of the co- axial conductors in mm ?

Sounds close to what is needed for 75 ohms.

I presume you mean 1.6/5.6 Connectors (aka Siemans Connectors) These are
Connectors commonly used In telecommunications and the most Likely
candidates for your W&G tester. We usually get these Connectors from AC&E
http://www.acande.com.au/ - The socket on the Balun in the Side bar at the
right is a 1.6/5.6 Connector - AC&E can also Sell you Baluns to go to 120
Ohm impedance.
The plugs come in two Versions a screw on plug and a snap on Plug designed
for quick and easy disconnection ....

Try a search under "1.6/5.6" in Google and you should find other
distributers such as Benelec etc.

Firstly, thank you Phil and Richard for taking the trouble to answer.

The W&G manual has illustrations of both the 1,6/5.6 and 2,5/6 types so I
know what to call the sockets fitted to my units. Seems PMG in those days
standardised on the 2,5/6 for the leads on these units, so somewhere there
are loads of these plugs..

Thre transmitter and receiver connect together to make a tracking generator
and receiver, so you can turn across 0.006 MHz to 19 MHz and read dbs
attenuation. The tuning is fine so you can measure crystal series
resistance or resonant frequencies. It takes 4 of my plugs to lock the
units together, and I have only got one plug left - I have to poke a croc
clip into the receiver socket !

It is a 75 ohms type. I don't want to put something else on the units,
because I would have to butcher them and lose calibration.

The socket has a big threaded outer, similar to an N type, about 14 mm dia
on the outside of the thread. In that big meaty outer, is a smallish inner
hole about 6.8 mm. The centre contact accepts a 1.5 mm pin.

The cable is a 75 ohm type flex, 6 mm outside diameter.

I will check out http://www.acande.com.au/ as Richard suggests. I can't see
anything in the Farnell catalog which looks like my plugsr.

thanks
Roger

** Just how old is this pile of nuts and bolts ???

If Google give zero hits on the connector type number - you have
Buckley's chance.

Its to big to be a 1.6/5.6 then although it sounds like a larger version of
it.

Sounds like they probably won't stock it though as it sounds like it could
be a fairly old connector....

I dont think it sounds quite like any of these but I have seen connectors
that sound similair used on Telco Test gear and I have probably seen the
beasty somewhere - it actually sounds like a larger version of the 1.6/5.6
maybe you could browse the Connectors at :
http://www.amphenolrf.com/products/716.asp and just make sure that it is not
commonly called something else try 7/16, HN or Type N as it may be more
commonly known by an American name than the Europeon name if it is still in
use today.
