Nixie clock with Z5660M tubes

About Nixie clock Z5660M

In this clock, Z5660M nixie tubes are used to make a 6 digit display that displays time and date. The peculiarity of nixie tubes is its magic and very organic glow that cannot be replaced by any other types of modern displays. Nixie tube has 10 different electrodes (also called cathodes) inside the tube, each cathode represents a decimal  digit: 0, 1, 2 … 9. These are formed with thin wires. There is also 11th electrode (called anode) inside the tube. The tube is filled with a neon gas. Now, if around 150 volts are applied between anode and one of cathodes, the cathode starts to illuminate orange light. For example, if cathode has a shape of „5“ the orange light appears around „5“ wire.

The housing of the clock is made of a metal cover (available in black) and wooden plates. Wooden plates are stained with different stains and varnished afterwards. The customer can make the desirable combination when combining different colors of metal cover and wooden plates.

Every wooden case is a unique original and has it’s own number. That’s why the customer gets exactly the wooden case he/she choses from the photos.

Technical parameters

• RTC (real time clock) time accuracy @ -40 to +85°C: ±6 ppm
• Maximum voltage of the internal DC-DC converter for nixie anodes: 220 VDC
• Power consumption (max.): typ. 275 mA @ 12 VDC = 3,3 W
• Outer dimensions: 106 (height) x 80 (depth) x 285 (width)
• Weight: approx. 680…720 g (depends on material of wooden plates)
• Socketed Z5660M nixie tubes, allows easy change of broken tubes
• Digit height: 30 mm

Functional features

• Automatic date showing (default enabled – shows every minute last 3 seconds)
• Programmable automatic display switch off. Up to 6 different intervals are available which can be assigned to individual days of week (default off)
• Digits over count animation (default on)
• 12h / 24h hours modes (default 24h)
• Lead zero blanking (default off)
• Broken nixie tube detection & immediate switch off of the internal 200V DC-DC converter for nixie anodes. This makes the clock operation safe, even if the tubes‘ glass envelopes get broken
