  • First SOIC8-Packaged Hall-Effect Current Sensor With Integrated Current Path Introduced
    SOIC8-packaged Hall-effect current sensor with the current path integrated into the package for greater sensitivity and accuracy. Available in both 15 A and 5 A versions, it measures bi-directional ac or dc currents by using a Hall-effect magnetic field sensor to measure the field generated by the current flow
  • A Case Study: MR vs. Hall Effect for Position Sensing
    While both magnetoresistive and integrated Hall sensors measure the strength of magnetic field components, they do so in different ways and this can directly affect their successful use in a position sensing application. Choosing which of the two is a better fit for your application may require you
  • Sensor Technologies to Detect Pneumatic Cylinder Position - White Paper
    Over the years, many users have abandoned the use of reed switches due to their failure rate and have utilized mechanical or inductive sensors to detect pneumatic cylinder position. AMR and GMR sensors are smaller, faster, and easy to integrate and are much more reliable however; they must overcome
  • No problem with noncontacting sensors
    Invensys Sensor Systems, El Paso, Tex., (Clarostat Div.) has developed a rotary Hall-effect position sensor, the HRS100, that cuts cost by integrating all compensation circuitry into a single factory-programmed sensor ASIC. Resistive potentiometers or "pots " have long been used for rotary position
  • High-five to high-side current sensing
    High-side current sensing detects downstream shorts and avoids many sources of electrical noise and EMI. This ACS754 Halleffect current sensor from Allegro Microsystems measures isolated high-side currents up to 200 A using less space than a quarter. An exploded view of an Allegro Microsystems
  • Measure Angles on Rotating Systems with High Resolution
    and in this approach Hall sensors are of specific interest. The principal is well known and different sensors have been used in the automotive and measurement equipment successful for a number of years. Most applications use Hall sensors as simple switches, pulse generators, or field sensors. The system
  • Measuring the long haul
    . But where stainless tape is punched with a coded pattern and read by an optical sensor, the new method makes use of an extruded aluminum profile containing buried magnets. A special Hall-effect sensor detects the magnets and determines absolute position. These position multiplexer encoders, or Pomux
  • MICRO: Products
    , user-friendly software, and an improved interface for 300-mm automation standards and fab communications. (Semicon West, South Hall, Booth 1616) For use in delivery systems that feed ultrapure gases to critical process systems, Type 890-series Baratron compact digital pressure transducers feature capacitance
