SS360PT / SS460P Hall-Effect Sensor ICs

Honeywell's SS360PT / SS460P high sensitivity latching, Hall-Effect sensor ICs with built-in pull-up resistor are small, sensitive, and versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating north and south poles. The SS360PT is activated by a north pole while the SS460P is activated by a south pole.

Features and Benefits

  • Provides a fast response time with more efficiency in commutating a brushless DC motor
  • No chopper stabilization resulting in clean output signal
  • High sensitivity that operates from only 30 gauss typical at 25°C [77 °F] and 55 gauss maximum over the full -40°C to 125°C [-40°F to 257°F] temperature range, allowing for the use of smaller magnets or a wider air gap
  • Internal pull-up Hall IC design simplifies installation and helps reduce component count and system cost
  • Biopolar latching magnetics makes these products well-suited for accurate speed sensing and RPM(revolutions per minute) measurement
  • Sub-miniature, SOT-23 surface-mount package (SS360PT) supplied on tape-and-reel allows for compact design with automated component placement
  • Small, leaded, flat TO-92 style package (SS460P) allows for a compact PC board layout
  • Wide operating voltage range of 3 Vdc to 24Vdc allows for potential use in a wide range of applications
  • Built-in reverse voltage capability enhances the protection of sensor and the circuits
  • Robust design allows operation up to 125 °C [257 °F] RoHS compliant material meet directive 2002/95

Industrial/Commercial Applications

  • Brushless DC motor commutation for white goods and other appliances
  • Flow-rate sensing
  • Speed and RPM sensing
  • Tachometer, counter pickup
  • Motor and fan control
