SS360NT/SS360ST/SS460S are small, versatile, highly sensitive devices designed to respond to alternating North and South poles. High magnetic sensitivity of 30 G typical (55 G maximum) is provided without the use of chopper stabilization on the Hall element. This results in a clean output signal and the fastest latch response time in its class. Bipolar latching magnetics offer accurate speed sensing and RPM measurement. A wide operating voltage range of 3 Vdc to 24 Vdc allows for design flexibility in a broad array of applications. Small, leaded, flat TO-92 or subminiature SOT-23 packages offer compact PC board layout. Built-in reverse voltage provides protection of the sensor and the circuits. These devices are suitable for use in many industrial and commercial, transportation, and medical applications. They are ideal for brushless dc motor commutation, speed sensing and RPM measurement. Transportation applications include tachometer, counter pick-up, and motor and fan control.
