Applications for Magnetic Sensors
Magnetic sensors are used in many industrial applications for contactless current sensing, linear and angular position, and rotation sensing. Crocus’ magnetic sensors are designed to provide superior performance in all of these applications.
Crocus’ magnetic sensor products are based on its unique MLU-patented technology. In contrast to Hall devices that generally have low sensitivity, our magnetic sensors exhibit a far higher sensitivity, representing several orders of magnitude, low power consumption, high temperature operation, high frequency operation in the Mhz range, and reliability performance.
Magnetic Sensors for PDUs
The growth in cloud computing and big data analytics is one of the main drivers in the increase in demand for data centers and servers. The PDU (Power Distribution Unit) is a critical part of the data center infrastructure. As the demand for data centers has risen, so has the need for PDUs. PDU equipment is used to supply AC or DC electrical power to servers. Typically, the PDU provides power filtering and intelligent load balancing together with remote monitoring.
Robotics and Factory Automation
The adoption of robotics for factory automation is seeing high growth. Both linear and angular position sensing are imperative to carry out complex motor movements with high precision, repeatability and accuracy. With the need for faster more efficient production lines, magnetic sensors are also used for linear and angular sensing, safety switches, and proximity detection. Crocus sensors provide contactless measurement with high reliability and high performance to address the next generation of factory automation with robotics.
New regulatory requirements for energy and water conservation in appliances can only be accomplished through additional intelligent sensing. Crocus magnetic sensors provide the added intelligence for open/close door detection, fluid level, and contactless current sensing. Crocus sensors meet the high reliability and accuracy requirements demanded in new stringent appliance regulations for cooking and laundry appliances to vacuum cleaners and refrigerators.
When it comes to alternative energy such as with wind and solar, magnetic sensors provide contactless current sensing, angular position sensing and switches. For wind power, the angular position sensing allows for optimal wind power generation, while contactless current sensors provide solutions for power inverters and solar combiner boxes. Switches can also assist with safety applications in high voltage environments.

Magnetic sensors have gained traction in many consumer applications. These involve solutions based on current sensing, switching, position sensing and angular sensing. We design our magnetic sensors to provide superior performance in all of these applications.
Most of the applications in consumer products involve switching and current sensing. A number of products that use switching include cases and covers to protect smartphones and tablet screens, as well as laptops. With industry leading low power consumption at about 250 nA!
Magnetic sensors are widely used in a variety of consumer products such as printers, scanners, cameras, and flat panels. One of the fastest growing applications of magnetic sensors is mobile navigation – the electronic compass is a must have feature in mobile devices such as smartphones and tablets. Magnetic field sensors are also commonly found in gaming consoles and in many products with smart features.
Green Plug – Current Sensing in IoT
The Internet of Things (IoT) is one of the hottest trends in the high-tech industry. Growing awareness of sustainable development is heightening the adoption of green solutions for the smart home. Green solutions provide more intelligent and smarter operating systems enabling further reductions in energy consumption and intelligent networks, thus more effective energy management.
As a result, the full adoption of green plug and lighting solutions is set to rise in the smart home market. These intelligent solutions allow users turn on and off appliances and lights remotely, enabling real time energy consumption by measuring current and voltage. Magnetic sensors provide contactless current sensing along with the lowest switching solutions at 250 nA!
Powering Secure Element Microcontrollers with Crocus MLU
In a fast evolving mobile and connected digital world, data integrity and data security are the prerequisites for building efficient and trustworthy electronic solutions. Crocus MLU™ the next generation embedded memory, is particularly suited to applications requiring both security and performance, such as Secure Element microcontrollers, TPM microcontrollers, secure microcontrollers for connected devices and identification.
The unique attributes of MLU™ make it an ideal choice for storing small to large quantities of vulnerable data and secrets. With very fast write times and exceptional cycling, MLU is a cost-effective solution for specific technical IC designs.
Mobile Secure Transaction applications are the perfect fit for MLU as they require ultrafast over the air updates. MLU’s benefit for these applications is its capability to write words in nanoseconds rather than long-page write operations, such as Flash technology.
The ability of MLU™ to exhibit robust performance and deliver outstanding endurance and cycling makes it the best choice
for such high demanding applications.
When it comes to securing stored information and transactions, MLU brings superior advantages to traditional Flash and
EEPROM memory. The access performances of MLU are such that malicious behaviour requires different tools and means
to corrupt a microcontroller featuring MLU.
