Launching October 1, the RR121-2A32-362 magnetic sensor offers a compelling solution for applications seeking to have “smart” proximity sensing, particularly those involving bi-directional linear and rotary motion, including consumer electronics and industrial actuators, white goods, and automotive.
The RR121-2A32-362 magnetic sensor has a unipolar polarity response, with each channel set opposite to the other. This means that the sensor can differentiate quickly and easily whether an actuating magnet is approaching (or receding) from one direction or the other, thereby providing direction sensing with only one packaged device. The 20 Hz clock is fast enough to not miss an activation while still keeping overall current consumption less than 300 nA. Its high magnetic sensitivity allows it to operate with fields as low as 9 G, while it’s LGA-4 package measures a mere 1.4 mm x 1.4 mm x 0.45 mm, saving premium circuit board real estate. Taken together, the RR121-2A32-362 offers an incredibly small package, ultra-low average current consumption, and maximum sensitivity. All of these features provide unprecedented flexibility for design engineers, giving them complete freedom to build their ideal systems.
The RR121-2A32-362 magnetic sensor is ideal for applications ranging across the industrial, consumer, automotive, security, and energy industries where very low average current consumption, high sensitivity, and a small package size are required. Specific applications include open/close detection on portable consumer electronics including laptops and tablets, especially those with convertible screen orientations (i.e. tablet mode vs. laptop mode). Industrial applications include linear actuators, gate controls, and other motorized, dual direction conveyance scenarios. In other words, the sensors are ideal in any scenario involving movement at a hinge, or other angular type motion sensing where knowing the direction of travel matters.
