CMAX2 absolute miniature measuring system Extremely compact, flat & light
CMAX2 is a magnetic absolute miniature measuring system with up to 20 bit resolution, designed for measuring lengths up to 192 mm or for rotary applications with a diameter of approx. 61 mm.
The flat housing, which is only the size of a thumbnail, houses the sensors and evaluation electronics. Due to its minimal size and low weight, CMAX2 is particularly suitable for integration in space- and weight-critical applications, such as position and angle measurement in robots, torque motors, servo motors, etc..
- Space- and weight-saving installation solution
- Magnetic absolute measurement with up to 20 bit resolution
- Communication via BiSS-C or SSI
- Additional incremental output signals (ABZ quadrature signals, 5 V TTL)
