Amperex/Philips Z550M “Pixie” Cold Cathode Numerical Indicator Tube
Tube indicateur des chiffres décimaux à cathodes froides
Kaltkatodenröhre zur Anzeigung der dezimalen Zahlen

The Z550M uses a stencil mask with numeral-shaped holes arranged in a circle, instead of the shaped cathodes of the Nixie tubes. It has been developed to satisfy the need for a decade indicator tube which can operate directly from the low voltage electrical readout provided by transistor scalers (counters). It requires an input signal of about 5V at a current of about 50 μA.
