Inductive Encoder

Inductive Encoder

Our inductive contactless position sensor is a magnetic-free solution that is immune to stray magnetic fields. Inductive sensor technology uses a rotating or moving target to measure the coupling between the excitation coil and multiple receiver coils. These coils are achieved with printed circuit coils, and rotating or moving rotor targets are achieved with a simple stamped metal piece or PCB with a specific pattern.The design of receiving coils in different applications can be one or two groups, or even multiple groups, combined with a specific rotor design can achieve 360 degree Angle, radian, straight line and other high-precision measurement. Inductive contactless sensor chip can provide a variety of output interfaces: SIN/COS analog output, SPI/SSI absolute value protocol output, ABZ incremental output, UVW motor to trust signal output, PWM, linear analog output signal. Specific application fields of inductive encoders include: industrial servo motors and all kinds of BLDC encoders; Automotive position sensors such as automotive throttle bodies, electronic power steering, and accelerator pedals require linear and angular/rotational motion for a variety of applications.
