Frequently Asked Questions 

What is a hollow shaft encoder?

A hollow shaft encoder is a type of rotary encoder designed to mount directly onto a motor or shaft, eliminating the need for couplings and improving alignment.


Why choose a hollow shaft encoder over a shafted encoder?

  • Space-saving design reduces hardware complexity.
  • Direct mounting improves accuracy and minimizes mechanical wear.
  • Easier installation, making them ideal for industrial applications.

What are common applications for hollow shaft encoders?

  • Servo and stepper motors in factory automation.
  • Material handling systems like conveyors.
  • Wind turbines for rotational speed measurement.

How do I install a hollow shaft encoder like the HS35R?

For proper installation, ensure:
✔ The encoder is correctly aligned with the motor shaft.
✔ The set screws are tightened to prevent slippage.
✔ The electrical connections are secured per manufacturer guidelines.
