Posital Fraba IXARC Magnetic Rotary Encorders determine angular position using magnetic field sensor technology. A permanent magnet ? fixed to the encoder’s shaft creates a magnetic field which is sampled by a sensor ? that generates an accurate absolute position reading.
Signal Processing is the Key to High Performance
The technological leap that pushes POSITAL’s IXARC magnetic encoders to the performance level of optical systems is based on a new generation of sensor systems. The combination of a custom Hall-effect sensor and complex signal processing algorithms running on powerful 32-bit microprocessor results in a considerably improved resolution and accuracy, along with latency times of only a few microseconds.
Posital Fraba has also implemented an incremental interface and can now offer a complete range of encoder solutions.
Multiturn Innovation
POSITAL can also provide absolute multiturn measurements using a revolution counter system that uses an energy harvesting system based on the Wiegand effect. This system requires no gears or batteries. Eliminating batteries brings about many advantages. Batteries have a limited lifespan, weigh a lot, and often contain harmful substances. Gear units have disadvantages of their own being large, complex, costly and vulnerable to shock and vibration.
Regardless of the rotational speed, even at near-zero, the energy harvesting system generates short, powerful voltage pulses, sufficient to power the counting electronics. The result is a revolution counter that is independent of any external power supply. This technology, which has proven itself since 2005, enables maintenance-free reliable measurement of absolute positions, even in demanding environments, for years to come.
