A sealing ring for a vehicle wheel having a tubeless tire with two tire beads that are embodied on the radially inward side thereof. An electronics module includes multiplexer circuitry responsive to the one or more antenna output signals configured to divide an input signal spectrum into a plurality of frequency band components each of less than an octave bandwidth. The cam surface acts on the pin to move the pin between an extended position and a retracted position. Further, the first magnetic pole tip layer is connected to the first yoke layer at the extended part, and is insulated from the first yoke layer at the reduced part.
