Description SS361RT Honeywell Hall Effect Sensor , and SS461R are small, versatile, digital Hall effect sensor ICs that are operated by the magnetic field from a permanent magnet or an electromagnet, and designed to respond to alternating North and South poles. SS361RT Hall Effect Sensor is turned on by a North pole while the SS461R is turned on by a South pole. These latching digital Hall-effect sensor ICs have enhanced sensitivity of only 50 G typical, at 25°C [77 °F] that often allows for the use of less expensive magnets or wider air gaps. They offer a robust IC design with reverse polarity protection and 150 °C [302 °F] capability. FEATURES • Latching magnetics • Enhanced sensitivity • Wide operating voltage range • Built-in reverse voltage capability • Robust design • RoHS-compliant material meets directive 2002/95 Industrial • Speed and RPM sensing • Tachometer, counter pickup • Flow-rate sensing • Brushless dc motor commutation • Motor and fan control • Robotics control
