2 pcs. CT-IN-18 Colon Tubes
(Separators)
incl. mounting rubber and blue floor lighting
Example of use! Remark: The Nixie clock case and IN-18 Nixie tubes are not part of this offer!
(You will find Nixie tubes at my other offers!)
This offer includes 2 wonderful, new, CT-IN-18 colon tubes,
2 mounting rubbers and 2 blue LEDs for the floor lighting as shown here:

Scope of delivery:
|
- 2 pcs. CT-IN-18 colon tubes (new, unused, tested, matched in terms of colour and shape)
- 2 mounting rubbers
- 2 blue LEDs (Light intensity: 2000 mcd)
|
This set fits perfect to the IN-18 tubes at my other offers!
but also for similar tubes (with digit height 30-50 mm).
For example:
ZM1040, ZM1042, Z5660M, Z566M, Z5680M, Z568M, ZM1042/01, ZM1220, ZM1222, NL-7037, NL-7038, B-7031, B-7037, LC-631, NL-8971, NL-934, Z5220M, Z522M, 7031, 7037, B-8971, CD94, CV8090, GA12, GR10G, GR10J, GR10J/F, GR-211.
These colon tubes provide the opportunity to apply the included LEDs at the tube to generate the very impressive floor lighting effect.

You can use other LEDs instead of the included blue ones, of course.
You'll find the complete assembly instructions and the technical data of the tubes as pdf file here (6 MB).

| Remarks:
all dimensions in mm
The dimension 29 mm can be adjusted for other mounting situations by sliding of the colon tube in the rubber

Mounting notes and floor lighting of colon tube CT-IN-18
Fasten the colon tube by using the included mounting rubber. You can mount the rubber in a hole in a PCB board or in a hole in an assemby board.
Here an example (PCB):
 
After mounting the rubber, insert the colon tube from the bottom side into the rubber. Note the drawing "Drawing of colon tube CT-IN-18" above for that. After this, connect the colon tube:
 
If you want to use the floor lighting with LEDs at the colon tubes attach one LED at the front side (face side) of each colon tube. Do NOT illuminate the colon tube from the back side! I recommend to solder the LED directly to the PCB board. If you use an assembly board instead of a PCB board, you can glue the LEDs to it or build an appropriate holder for the LEDs.
Here you see an example for the illumination of the colon tubes:
The dots can be switched seperately of course, so that not only a colon is shown but the singel dots (e.g. for the date).
2 dots switched on:
   
1 dot switched on:
   
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 IN-18 Nixie tubes are not part of this offer!
