Speed Sensors

There are two primary types of speed sensors: passive and active. Passive speed sensors are designed to detect the presence or absence of ferrous metal targets, such as gear teeth or other rotating components. They operate based on the principles of magnetic induction and can generate an output voltage proportional to the target’s rotational speed. These sensors often come in various sizes, thread types, and output voltages, making them versatile for a wide range of applications.

Active speed sensors, on the other hand, not only detect the presence or absence of ferrous metal targets but also measure their rotation speed. These sensors utilize advanced technologies, such as Hall effect or proximity sensing, to provide high-accuracy measurements. They can be used in numerous industries, including automotive, aerospace, and industrial applications.

Application features:

  • Cost-effective: Both passive and active speed sensors provide an affordable solution for detecting ferrous metal targets and measuring their rotation speed, respectively.
  • Robust and durable: These sensors are designed to withstand various environmental conditions and last for a long time, making them a reliable choice.
  • Easy installation: Speed sensors are typically easy to install, ensuring a hassle-free experience for users.
  • Low maintenance requirements: With minimal maintenance needs, these sensors are a convenient choice for various applications.
  • High accuracy and precision: Active speed sensors, in particular, offer high accuracy and precision in measuring rotation speeds of ferrous metal targets.
  • Exceptional resolution: Active speed sensors provide outstanding resolution, ensuring accurate and detailed measurements.
  • Outstanding frequency response: These sensors demonstrate excellent frequency response, making them suitable for a wide range of applications.
