SZMB-9 Magnetoelectric Speed SensorDetailed product description：

The SZMB-9 magneto electric speed sensor can convert angular displacement into electrical signals for counting by a counter. It has the advantages of small size, sturdy and reliable, long service life, no need for power supply and lubricating oil, and can measure the speed and linear velocity of various magnetic materials such as gears, impellers, disks (or shafts) with holes (or grooves, screws) without contact.
