Magnetic Position Sensors
Low-Cost, Bipolar, Hall-effect Sensors
SS40A/SS50AT Series
FEATURES • Small size • Low cost • Reverse polarity protection • Sensitive - bipolar
magnetics respond to alternating north and south poles • Thermally balanced, integrated circuit over a full temperature range • Stable operation
TYPICAL APPLICATIONS • Cooling fan control in
computers and appliances • RPM (revolutions per
minute) sensing, speed control • Brushless dc motor commutation • Position sensing and motor control • Simple magnetic encoder • Flow-rate sensor
The SS40A/SS50AT Series sensors are low-cost, bipolar, Hall-effect sensors. These sensitive magnetic sensors offer reverse polarity protection and deliver stable output over a -40 °C to 125 °C [-40 °F to 257 °F] temperature range.
