Extension board IK1R
system components for rotary encoders WV58MR and WH58MR
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 insafety-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.
- redundant single-axis inclination sensor 0 ... 360°
- MEMS capacitive measurement principle
- Can be used in applications up to performance level PLd
- temperature-compensated from -40 … 85° C
- simple function enhancement
