Magnetic Resistence Current Sensor
esigned in accordance with Honeywell's patented technology, the CSN Series Magnetoresistive Current Sensors provide superior sensor performance and high accuracy in current measurement applications. The current sensor uses an ASIC (Application Specific Integrated Circuit) and a magnetoresistive (MR) Honeywell magnetic sensor with extremely low temperature drift, so the measurement results are stable, repeatable and highly accurate. The sensor operates from a +5 volt unipolar supply with an internal voltage reference of 2.5 volts, which is very easy to obtain. The sensor can operate from either an internal reference or an external reference, allowing one reference voltage to be applied to multiple sensors simultaneously without offset imbalance. Three pairs of primary pins allow the sensor to be configured for various ranges. The current output signal uses different load resistors depending on the application. The sensor offers great flexibility and excellent performance to meet the needs of a wide range of applications. Features:
