Magnetic field sensor project using AD22151 IC from Analog Devices, The AD22151 is linear magnetic field transducer. The sensor output is a voltage proportional to a magnetic field applied perpendicularly to the package top surface. The sensor combines integrated bulk Hall cell technology and instrument technology to minimize temperature related drifts associated with silicon Hall cell characteristics.

            Thank you. Then what is the total thickness? I mean the top to bottom height. I am considering of placing this entire sensor in a 3.9 mm thickness space. Is it possible?
            I need 5 pieces currently.

          PCB Thickness without components 1.6mm
          PCB and Components 3.5mm without header right angle connector
          PCB + Components + Connector =5.5MM
