  • Sensor for coin acceptor
    Patent number: 6536578
    Abstract: A sensor for a coin acceptor includes an inductor connected in a series resonant circuit. The sensor coils are arranged in a series resonant configuration with the resonant capacitance made up of two identical capacitors, one on either side of the sensor. The series resonant configuration reduces the effects on sensor readings of common mode noise on the coin acceptor power supply.
