CAM 20mm Transponder Coil

20mm Transponder Coil (SMD) for Position Targets

CambridgeIC’s resonant inductive position sensing technology allows linear or rotary sensors to be built using conventional PCB fabrication processes. Sensors detect inductively coupled targets without contact.
20mm Transponder Coils are wound ferrite cored inductors for surface mounting to a PCB. They form the inductive component of the resonant circuit inside a target, and allow targets to be built using PCB fabrication and assembly processes too.
The 20mm Transponder Coil is also available with capacitance connected across its SMD pads, for use as a resonator assembly.


  • 2 alignment Pins for accurate registration on a PCB
  • 4 large solder terminals for secure fixing to a PCB
  • High Q-factor for strong signals and high resolution
  • Stable inductance
  • Magnetic geometry optimised for inductive sensing


  • Operating Temperature Range -40°C to +125°C


  • Inductively coupled resonant circuits
  • Through hole contactless rotary position sensors
  • End shaft contactless rotary position sensors
  • Contactless linear position sensors
