Claims

[Scope of utility model registration request]

A cathode 4 and a plurality of anodes 9 arranged oppositely in a vacuum
. A magnet 5 that applies a deflection magnetic field;
The vacuum tube 6 includes a detection means R19R2 for detecting the deflection of the electron flow due to the magnetic field of the magnet 5 based on the value of the current flowing through the anode 9.10, and the vacuum tube 6 has an electron convergence plate 2 for converging the electron flow. A proximity sensor featuring:
