Piston and cylinder unit including a radially installed piston position detection unit

A piston position detection unit for detecting the position of a piston in a cylinder of a piston and cylinder unit, comprising:

• a housing being designed to be cylindrical and including a longitudinal center axis;
• and
• an electronic unit being arranged in the housing and including an antenna for sending and receiving high frequency electromagnetic wave signals through the housing, the sense of direction of main radiation of the antenna extending perpendicularly to the longitudinal center axis of the housing, wherein
• the piston position detection unit is designed to be arranged in a mounting bore in the cylinder such that an interior of the cylinder is sealed from the surroundings of the piston and cylinder unit by the housing, and
• the piston position detection unit is designed to be arranged in the mounting bore in the cylinder such that the high frequency electromagnetic wave signals are directed through a sensor signal bore in the cylinder, the mounting bore being operatively connected to the interior of the cylinder by the sensor signal bore, the mounting bore extending in a radial direction and the sensor signal bore extending in an axial direction.
