Non-Contact Rotational Detectors for Precision Speed Measurement

Non Contact Rotational Speed Detection

Techris Systems offers a comprehensive range of Ono Sokki Rotational Detectors—advanced, non-contact sensors engineered for accurate rotational speed detection across diverse industrial applications.

Reliable Non-Contact Rotational Speed Detection

Ono Sokki’s magnet-type rotational detectors utilize an internal Hall element combined with a permanent magnet, DC amplifier, and voltage regulator. This innovative design responds directly to magnetic flux changes, allowing the generation of a clean rectangular waveform signal from very low speeds up to high rotational velocities.

Thanks to their compact design, these detectors feature built-in signal indicators, enabling easy verification of operation and mounting position during installation. Choose from detectors that require an external detection gear or built-in gear type sensors to fit your specific application needs.

Available Ono Sokki Rotational Detector Models:

• MP-981 General Purpose: Ideal for standard rotational speed measurement with high accuracy.
• MP-9820 High-Speed Detector: Designed for applications requiring detection at very high RPM.
• AP-981 Water and Acid Proof Detector: Engineered for challenging environments exposed to water, acid, and corrosive substances.
• 
  

Applications

Ono Sokki rotational detectors are widely used for engine speed measurement in automotive testing, machinery monitoring, and various industrial speed control applications where precision and reliability are critical.

Key Features:

• Non-contact detection method prevents mechanical wear and eliminates interference with the rotating object.
• Measures extremely low rotation speeds, with the MP-981 model capable of detecting speeds as low as 1 r/min.
• Compact, all-in-one optical detector design for easy installation and maintenance.
• Durable and versatile models including water and acid-resistant options for harsh environments.
