Extension Board IK1

system components for rotary encoders WV58MR, WH58MR, WV5800M, WH5800M

The PURE.MOBILE extension board IK1R is a redundant safety single-axis inclination sensor, which has been specially developed for use in mobile machines. It can be used in safety-critical applications – up to performance level PLd. PURE.MOBILE extension board s can easily expand the range of functions of the desired rotary encoder. 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
