Multi-functional switching offers high sensitivity, reliability and low power consumption

Crocus has announced the release of its new CT832 Digital Magnetic Switch, the CT83X series. The innovative device meets these demands by offering system designers greater efficiencies by providing both a digital and analog output that serves multiple applications from a single switch with lower power consumption; when configured solely with a digital output it becomes the industry’s lowest power consuming switch with only 200nA. “Our customers and partners have been waiting for a magnetic switch that combines the lowest power consumption with multiple functionalities to bring intelligence sensing to wide a variety of applications and systems,” states Zak Deiri, chief sales and marketing officer, Crocus Technologies. “With the CT83X, we deliver on their needs to improve performance across consumer goods, industrial applications, and IoT applications.” Approximately the size of a typical shunt resistor, the device not only replaces it but provides added intelligence with enhanced switching and current monitoring capability. The device either detects the magnetic field as generated by a permanent magnet or induced by a current-carrying conductor. As a contactless current switch, the device monitors the current on a wire or the PCB trace used with many IoT applications, appliances, and industrial automation environments. The contactless nature of the device enables safe, non-invasive current monitoring. When used as a proximity switch, it will detect window or door movement in intrusion alarm systems and appliances, while the additional analog output adds another dimension of intelligence by sensing if the window or door is ajar with its proximity detection capability. Unlike typical Hull sensors, the device offers high sensitivity for large air gap environment to provide system designers greater flexibility.
