Linear position sensor

  • The Linear Non contact hall’s effect Displacement transducer is used to detect the displacement of system which correspondence to the Linear motion of the shaft of the sensor.
  • The Output signal correspondence to 0 to maximum stroke length with standard stroke length as 5mm,10mm, 20mm, 25mm and 30mm. Customization in the stroke length is possible.
  • Since the Product is based on Contactless Hall's effect Technology it has very long life.
  • Linear Hall effect transducer 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 / 4-20mA Analog Ratio matric Output.
    • 12 bit resolution +/- 15Vdc input and +/- 5Vdc output
    • 12 bit resolution PWM Output.
    • Hollow shaft, Shaft on both sides and Threaded shaft to have variable shaft tops available.
    • Metal housing of 18 X18 alluminum housing version available.
    • Spring Return and Non spring return version available.
    • Metal connector with IP protection possible
  • Benefits
    • Non Contact Linear Position Sensor based on Magnetic Technology.
    • 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 LHS-X-XX below points needs to be taken into consideration.
1) The Centering diameter of 8.1mm need to be perpendicular to the linear motion.
2) The PCD (pitch Circle Diameter to mount the sensor should be 33.5mm with a hole of 5mm dia.

Magnetic Cross Talk

If two LHS units are to be installed closer than 2 inch (measured between the center of both shaft), a magnetic shield, such as a small steel plate should be installed in between to prevent one from long with that a sensor from causing small changes  in reported  position through magnetic field cross talk.
