Rotary Multiturn Sensors

  • Rotary multiturn Angle sensor is based on contactless magentic hall's Effect technology. (RHMS-22).
  • RHMS is in a compact dimension of 22mm OD with Maximum 10 turn (3600 deg) and 20 turn (7200 deg)
  • The Output signal correspondence to 0 to maximum number of turns and degree. Standard being 10 turn and 20 turn. However we customise the sensor based on application requirment.
  • Since the Product is based on Contactless Magnetic Technology it has very long life, No effect of radial load upto certain extent, High vibration withstanding rating.
  • The USP of the Product is with inbuild signal conditioner card with 0- 10Vdc output or PWM output or 0-5Vdc output. Beside this the back side slot allows the end user to precisely set the starting and end point.
  • For angle measurement less than 360 deg we have sensors with model number RHSS12, RHSS22 and RHSS48.
  • RHMS is a economical product with highly good accuracy and resolution of 12bit over a full range.
  • Variants
    • 12 bit resolution 5V input and 0.5 to 4.5Vdc Analog Ratio matric Output.
    • 12 bit resolution 24V input and 0 to 10Vdc Analog Ratio matric Output.
    • 12 bit resolution PWM Output.
    • Electrical angle can be 3 turn, 5 turn, 10 turn, 15 turn and 20 turn.
    • Mechanical angle can be 10 turn or 20 turn.
    • Shaft on both sides and Threaded shaft available.
    • Metal housing housing version available in 48mm dia.
    • Terminal Block, Turrets, Fly wire or cable output version available.
  • Benefits
    • Non Contact Linear Position Sensor based on Hall Effect Tenology.
    • Accurate Linearity upto 1% F.S. or 0.5% F.S (on request)
    • Extremely Long Life.
    • Extremely Compact in Size.
    • Short Circuit, Overvoltage and Reverse polarity protected.

Mounting

For best performance of RHMS-22 below points needs to be taken into consideration.
1) The hole in the panel should not be more than 9.5mm.
2) RHMS-22 should be mounted with Star washer given along with the product and perpendicularity between the panel and axis of Sensor should be maintained.

Magnetic Cross Talk

 If two RHMS-22 units are to be installed closer than 4 inch (measured between the center of both shafts), a magnetic shield, such as a small steel plate should be installed in between to prevent one encoder from causing small changes in reported position through magnetic field cross -talk .
