BMIX magnetic, battery-backed quasi-absolute encoder Permanent position detection, even in de-energized condition
The ELGO measuring system BMIX is based on the physical principle of length and position measurement by using magneto-sensitive components. It is used for a high-precision detection of the position, length or speed. A rechargeable battery line integrated in the sensor housing transforms the incremental measuring system into a quasi-absolute measuring system, as the current position is - even in the de-energized state - permanently detected and furtherprocessed internally. Under optimal charging and ambient conditions, the operating time of the batteries is up to 6 months after disconnecting the supply voltage.
- Quasi-absolute length and position detection
- Movements are even detected in de-energized condition
- Proven magnetically based measuring technology
- Wear-free, contactless measurement principle
- Analog output interface (voltage or current, CANopen (DS406) interface
- High schock and vibration resistance
- Robust against dust, dirt, smoke and water
