Low power contactless angle sensor CP-16U

TMR sensing system


PEWATRON has released the new CP-16U non-contact angular sensor which incorporates the latest tunnelling magneto-resistive (TMR) technology. The CP-16U is a compact, lightweight and very low torque sensor that can be used up to 100°C temperature. It is designed for a range of ±45°, while CP-16U-1 covers a wider range of ±60°. The main advantage of TMR is very low power consumption: only 0.6 mA allows the CP-16U to be used in battery powered systems. Another big advantage is higher output signal than the former MR technologies. The output signal ranges from about 25% Vin to 75 %Vin. Typical applications include thread tension control, valve positioner and paper thickness sensing.

Technical details: 

  • Power consumption < 0.6 mA
  • Low torque < 0.1mNm
  • Input Voltage  3 … 5.5 VDC
  • Output sensitivity: 0.35 to 0.65 %Vin / °
  • Angular Range ±45° or ±60°
  • Independent Linearity: ±1.5%FS @ FS=90°
  • Infinitesimal resolution
  • Temperature range: -40 to +100 °C
