IN-18 (ИН-18) / IN-4 (ИН-4) Nixie Tube Socket
incl. blue floor lighting

This offer includes one new IN-18/IN-4 Nixie tube socket kit as shown here:



Scope of delivery:

  • 1 socket board
  • 14 tube contacts (pin receptacles)
  • 3 blue LED (Light intensity: 2000 mcd) (If you need more than 3 LEDs, for use with the IN-4 Nixie tubes please write me!)

Applications of the socket
This RSH31 Nixie tube socket with LED can be used for all tubes with RSH31 base.
The Russian spelling of this base is “РШ31”.
Here you see an example picture of the RSH31 base:

The currently known Nixie tubes and Dekatrons with this base are:

  • Nixie tube IN-18 (Russian spelling: ИН-18)
  • Nixie tube IN-4 (Russian spelling: ИН-4)
  • Nixie tubes IN-7, IN-7A and IN-7B (Russian spelling: ИН-7, ИН-7A, ИН-7Б)
  • Dekatron tube A-201 (Polyatron)

The socket provides the opportunity to apply the included LEDs under the tube to generate the very impressive floor lighting effect.

Example of use! Remark: The Nixie clock case and tubes are not part of this offer!
(You will find the tubes
at my other offers!)

You can use other LEDs instead of the included blue ones, of course.
You can use the tube contacts in your own PCB layout, too.
The socket has a black coated surface. This is very expedient for the case mounting at a Nixie clock, because the black surface looks neutral.

You'll find the complete assembly instructions of the socket here and the technical data of the tubes as pdf file (6 MB).

Here you see the completely assembled tube socket:

You can use one, two, three or four LEDs. For a balanced glow in combination with IN-18 tubes I recommend 2 or 3 LEDs, at which if 3 LEDs are used, the front LED should not be assembled (see pictures). You never should use 4 LEDs in combination with a IN-18 tube!
The following 4 pictures show the socket in all 4 variants (computer animation):

not recommended)

2 LEDs (recommended for IN-18 – standard intensity)

Remark: The shown tubes are not part of this offer!

Here you see the drawing of the assembled socket:

  • Remarks:
  • all dimensions in mm
  • The drawing shows the standard alignment for IN-18 tubes, at which the tube front (pin 4) shows an angle of 32.5° to the mounting holes.
  • The Drawing shows the 4 LED positions. Please note that for the IN-18 tube only 2 or 3 LEDs are recommended. The LED in front should not be used in combination with IN-18 tubes, because it blinds!
  • The tube contacts also will fit for many other Nixie tubes. E.g.: Z566M, Z5660M, Z568M, Z5680M, IN-18 and many more.

    Example of use: Nixie clock with IN-18 tubes and colon tubes CT-IN-18 mounted in a case
    At the following pictures you see a IN-18 Nixie clock mounted in a gorgeous stainless steel case as example. Exactly the same principle as described in the assembly instructions (here). There’s no limit for your fantasy for the case, of course. Have fun building it!

    Remark: The shown clock case and tubes are not part of this offer!
