C-Series Inductive Rotary Encoders
Ultra-thin and lightweight, with a large hollow shaft and non-contact design — ideal for compact applications with limited space. It can be seamlessly installed in robot joints or multi-axis automation equipment. The encoder is suitable for position feedback or improving commutation in frameless motors.
The non-contact absolute C-series encoder meets stringent industrial environment standards and offers a cost-effective, accurate, and reliable position sensing solution; customization options are available.

Frequently bought together - Magnetic encoders
Direct drives need high-quality position signals to ensure optimal performance. Perfect measuring signals can enhance the surface quality of machined workpieces, reduce the machine frame's vibrations, minimize velocity-dependent motor noise, and prevent excessive heat generation in the motor.
Mosrac recommends using a magnetic encoder to enhance the accuracy, speed stability, and thermal behavior of direct drive axes. Because there is no mechanical transmission between the encoder and the feed unit, the position signals are not susceptible to inaccuracies or delays.
