MJ-VR60 Passive magnetic speed sensor

Brief Introduction 

●  MJ-VR60  Passive magnetic speed sensor can convert angular displacement into electrical signals for the counter counts, as long as non contact it can measure the rotate speed and linear velocity of various magnetic materials such as gear, impeller, hole (or slot, screw ) disk.

●  The sensor has many advantages: small size, strong reliability, long service life, no need of power and lubricants and so on, it also can be matched with normal secondary instruments.

Matters Need Attention In Use

1. When installing the sensor should not damage the shell M16 x 1 screw thread of the sensor, hex nut should rotate freely, there is no loose after the hex nut is fixed. 

2. When installing the sensor should make the measured gear not contact the sensor. And minimize the gap δ to improve the output signal amplitude value.

1. When installing the sensor should not damage the shell M16 x 1 screw thread of the sensor, hex nut should rotate freely, there is no loose after the hex nut is fixed. 

2. When installing the sensor should make the measured gear not contact the sensor. And minimize the gap δ to improve the output signal amplitude value.

 

1. Output waveform: approximate sine wave (≥50r/min )

2. Output signal amplitude:

  50r / min > 300mV 

Sensor core and measured gear tooth tip clearance δ0.5 1.2mm

  Measured gear modules M = 2  Gear Z = 60   Materials: electrical steel

Signal amplitude is proportional to the rotating speed and inversely proportional to the gap between the iron core of the sensor and the measured gear tooth tip.

3. Frequency response: 30 ~ 10KHz

4. Service time: continuous use 

5. Working  temperature: -50+120℃   -50+200℃  ( special order )

6. Output forms: X12K4P four-core plug or directly lead

7. Dimensions: outside diameter M16×1; M18×1.5.

  Overall length is 80mm,Overlength needs should be custom-made.

8. Weight: about 120g (excluding cable)
