The PURE.MOBILE extension board IK1 is a single-axis inclination sensor, which has been specially developed for use in mobile machines. PURE.MOBILE extension board can easily expand the range of functions of the desired rotary encoder without the necessity of changing its design. In addition to its known functions such as position and speed measurement, the rotary encoder is enhanced by additional useful functions.

Profile IK1:

  • single-axis inclination sensor 0 ... 360°
  • MEMS capacitive measurement principle
  • temperature-compensated from  -40° C … +85° C
  • simple function enhancement
