Positioning / Proximity Sensor

Through the innovative use of RFMicron’s Chameleon™ technology the Magnus family of ICs can be used as a proximity / positioning sensor.

Positioning Sensor (relative to metal)

A positioning sensor mounts the tag onto one surface and a metal patch onto another surface that moves relative to the tag. As the patch moves closer to the tag, the inductance of the tuning loop decreases. The Chameleon Engine compensates for the lower inductance with higher capacitance which is then readable as a SENSOR CODE with higher value. The sensor reports closer proximity with higher sensor codes.
