Inductive Encoder iCs
Inductive encoders are robust solutions, suitable for applications where position measurement is necessary in a harsh environment. The Inductive Encoder iCs can be connected directly to the coils in an inductive encoder.
The iCs include a coil driver to generate an excitation current, and also integrate the signal processing to demodulate and condition the receiver coil signals from two independent channels, making it suitable for high resolution absolute position sensing.
Applications:
- Robust absolute position sensors
- Drive speed and torque control
- Brushless motor commutation
- Robots, AGV, vending machines
