I have a number of octal sockets that can be either screwed to a surface, or clipped onto TS-35 din rail.
Although they are meant for-plug in relays, it appears that the pattern/size of the socket is slightly smaller than the pattern of the octal valves to which we are accustomed.

I need to force an octal valve into the socket. Is there a difference between octal relay bases and valve bases?

Oh. And where can I get a one metre length of TS-32 din rail? It does not seem to be very popular lately.

Picture of socket submitted.

I don't have the dimensions of valve vs relay sockets, but I can say that sometimes relays are a very tight fit in their octal bases.

Why are you using relay sockets for valves?

As for the DIN rail: http://au.rs-online.com/web/p/din-rails/0467365/

There is also a ten pin version of this socket - popular with some brands of hospital nurse-call systems.

And an 11 pin version.

And what valve? If I replace a 6V6 or 5Y3 socket I use ceramic as it can better handle the heat.

What's it's thermal properties?

Electrical fittings have to withstand at least 90 degrees and if enclosed they have to withstand at least 105 degrees. This includes wiring. There are higher temperature ratings for various commercial and industrial situations.

Dear GTC. I am not using the octal relay bases for valves.
Sometimes things come my way too cheaply to knock back.

I do use a lot of relays at work and DIN mounted relays would simplify mounting.

Since this is in the Tech Talk forum, I shall post a couple of poorly focused pictures,
of some lift control, on which I am working.
This almost completed set-up is controlling, two side-by-side lifts, thirty floors, and has intercom interface
with visual indication of status, and fail-safe operation.

There are one hundred and forty-four relays here.

Wayne.

Okay got it now. When you said "I need to force an octal valve into the socket", we took that to mean you have a need to use the relay socket for a valve.

I have been in the lift control room in an old building with numerous lifts. The control relays sounded a bit like an old PABX room in operation.

Electrical Wholesalers keep din rail usually in 1 metre or 2 metre lengths.
