HYA02 SENSOR

HYA02 SENSOR

The HYA02 is a non-contact magnetic induction sensor that generates a dual-phase digital signal with a 90-degree phase difference, enabling precise measurement of travel distance and speed.

Its output format is fully compatible with traditional encoders.

With versatile applications, it is ideal for hydraulic presses, automation systems, and machinery without servo motors, delivering an efficient, reliable, and cost-effective motion monitoring solution.

Installation & Usage Guidelines
  • Align the sensing surface perpendicular to the gear tooth surface, maintaining a 0.1–0.6 mm gap.
  • Avoid using sharp objects or screws for mounting; flat clamping is recommended to secure the sensor.
  • The target object should have a height difference of at least 0.15 mm. Its surface must be smooth and may be coated with a non-magnetic material, such as chrome.
  • Ensure proper alignment between the sensor and the target to maintain stable and accurate signal output.
