摘要：A proximity sensor comprises a magnet which generates a magnetic field and amagnetic field sensor. The magnetic field sensor includes a radio and an antenna whichcan transmit an output signal on a plurality of output frequencies. A microprocessor isprogrammed with a plurality of data protocols. Each of the output frequencies operateson at least one of the data protocols. There is a dip switch which is actuated to provide acode to the microprocessor. A data protocol is implemented by the microprocessorbased on the code. There is a MEMS oscillator programmed to a discrete frequencybased on the data protocol implemented by the microprocessor. The MEMS oscillatorprovides the discrete frequency to the radio. The radio is provided with single phase-locked loop which generates the output signal based on the discrete frequency. Thesingle phase-locked loop may be a ×32 multiplier.
