SS40A

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. Operation from any dc supply voltage from 4.5 Vdc to 24.0 Vdc is acceptable. The SS40A/SS50AT Series sensors build upon Honeywell’s popular magnetic position sensors and offer seve...
