Honeywell Sensing and Control’s new SS360PT and SS460P High Sensitivity Latching Hall-Effect Sensor ICs with Built-in Pull-up Resistors are high performance yet economical sensor ICs well-suited for demanding, cost-sensitive high-volume applications, such as commuting brushless DC motors used for medical equipment and appliances as well as for flow-rate sensing, speed and RPM sensing, tachometers, counter pickups, motor and fan controls.
The SS360PT/SS460P Hall-Effect sensors provide reliable switching points with a high magnetic sensitivity of 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.
These sensor ICs do not use chopper stabilisation on the Hall element, providing a cleaner output signal and a faster latch response time when compared to competitive, chopper-stabilised, high sensitivity Hall-effect bipolar latching sensor ICs. Latching magnetics make these sensors well-suited for accurate speed sensing and RPM (revolutions per minute) measurement.
The sub-miniature, SOT-23 surface mount package (SS360PT) allows for compact design with automated component placement. The small, leaded, flat TO-92-style package (SS460P) allows for a compact PC board layout design. Wide operating voltage range of 3Vdc to 24Vdc provides for potential use in a wide range of applications. Built-in reverse voltage capability enhances the protection of the sensor and the circuits, and the robust design allows operation up to 125°C (257°F).
These Hall-Effect devices are available in two package styles: the SS360PT in the miniature SOT-23 surface mount package and the SS460P in the leaded, flat TO-92-style package. The SS360PT is supplied on tape and reel (3000 units per reel). The SS460P is available in a bulk package (1000 units per bag).
