Other noncontact magnetism-based sensors go beyond potentiometric sensors using resistance-based track-and-wiper techniques. However, they still require that a shaft be attached to the sensor’s housing. In contrast, touchless rotary sensors use a magnetism-based measurement technique that doesn’t require physical contact between the marker and sensor. As we’ll explore, this setup provides several benefits to a wide range of applications. Learn about how touchless rotary sensor work, touchless sensor uses, advantages in using them and more in this informative guide.
