    Hello, 

    I have a few clarification questions about this application: 

    • What are the sizes and materials of the coins that need to be detected? 
    • How far away from the sensor will the coins be? 
    • Will the coins always have their flat side facing the sensor coil? 

    Thank you, 
    Justin
