The RR122-1A22 TMR sensor features an operating frequency of 10 Hz, a voltage supply range of +1.7V to +5.5V and an extremely strong magnetic sensitivity (9 G or 0.9 mT) in an ultra-miniature package size at a highly-competitive price. Boasting the world’s lowest current drain (75 nA) for an active magnetic sensor, the RR122-1A22 Series TMR sensor is ideally suited for performing the “wake up” or “turn on” function for battery operated and power sensitive applications.
