rotation detector

This product is a sensor that measures the rotational speed of rotating objects. The sensors we handle can be broadly divided into magnetic and optical types, and measurements are conducted by attaching gears or reflective seals to the objects. They are primarily used for monitoring rotating bodies, playing a significant role in safety management to ensure that equipment operates stably, and are also utilized in customer devices for monitoring and controlling rotational speed. Although this sensor is low-cost and not particularly prominent among measuring instruments, it plays a very important role in industries that deal with numerous rotating bodies.

All of these sensors have a long lifecycle, and the MP-981, which has been a representative model of magnetic types for many years, has been in production for about 50 years.
Maintaining stable supply over a long period may seem easy, but in reality, it involves many challenges. We continuously engage in diligent creativity to ensure that changes in parts do not affect mass-produced items, and we are also conscious of properly passing on technology as designers change over time. On the positive side, I feel that my perspective has broadened through the development experience of this sensor. While specifications and performance, such as numerical specs, are important indicators for measuring instruments, I have also realized the importance of durability and reliability, such as "how resistant to breaking it is" and "how much customers can continue to use it with peace of mind," learning the significance of added value beyond just specifications.

This sensor plays a very important role in safety, known as "monitoring rotating bodies," and is often used in harsh environments. To avoid causing troubles in such environments, we strive to ensure a stable supply of high-quality products and work daily on improving the skills of our manufacturers and creating a workplace that does not produce defective products. It can be quite challenging since the quality is affected by the manufacturing process of the sensors, but we communicate and come up with ideas among the team members.

I have been involved in the manufacturing of this sensor for about 40 years, and there are customers who have been using it for many years. It makes me happy to feel the trust in our sensors.

In April 2024, we launched the Magneto-Electric Rotation Detector MP-9810 as a successor to the MP-981. We have improved environmental resistance while maintaining compatibility with the previous model, ensuring that customers who have used the former model for many years can replace it without any issues. We hope that it will not only continue to be used with confidence but also contribute to a wider variety of environments and measurement scenes than ever before.
