Base Octal (Int.Octal, IO) K8A, USA 1935
Filament Vf 6.3 Volts / If 0.3 Ampere / Indirect

Vacuum diode in which the current is controlled by magnetic field applied from outside. Typical operation as magnetic field linear sensor:

  • 150 V anode
  • 6 kohms load
  • 0 to 11 mA anode current, 30 mA max
  • 100 to 50 gauss magnetic field range
  • 2 mA per gauss sensitivity.

The tube may be operated as magnetically controlled switch. Typical operating conditions:

  • 100 V anode voltage
  • 100 ohms load
  • 1.6 W plate dissipation
  • 14 to 30 mA anode current at 50 gauss, falls to 0.2 mA at 70 gauss.
