Resonant circuit
Hysteresis adjustment
Distance adjustment
Temperature compensation of the resonant circuit; possibly with series
resistance for the purpose of adjustment. The diode is not absolutely necessary.
Whether it is used or not depends on the temperature coefficient of the resonant
circuit.
Integration element. At pin 3 (integrating capacitance) we recommend a
capacitor of typ. 1 nF. To increase noise immunity this capacitor can be
substituted by an RC circuit with, e.g., R
