enrich Coreless Current Sensors

INTRODUCTION

Wolfgang Endrich.

Do you know how much…

…laws exist? The economic situation is bad. You shouldn’t make hasty judgments,  because the inheritance, the current government started, was full of holes. One is that Putin didn’t take the annexation of Crimea seriously. The railway system was neglected Roads and bridges too and then came Corona. After that, a lot was different. The starting conditions for the new government were real Not rosy, but the filling of the ministerial positions was – to put it mildly – unfortunate. In February 2022 Ukraine was invaded, and it was discovered that unfortunately, the staffing not having the expertise was the priority, but rather the merits in party work and/or other reasons.

Examples: A defense minister runs into high heels around the military training area When war breaks out, she offers Ukraine 5,000 steel helmets. Another is an expert in poetry, but his knowledge of bankruptcy law is not very developed. Another person showed despite having studied law for many years enormous gaps in knowledge. The coalition argues and enacts Laws that became a real hit with the public, like this Heating law. It turned out that our chosen government many cases the expertise and the feeling for the people’s needs and desires. China has been broken, the population is highly unsettled and dissatisfied. Party political wishes in Social areas could not be met. Germany has become a regulatory state in which everything is regulated.

The energy transition is necessary because We cannot be indifferent to global warming, however, without the understanding and consent of the population, the most beautiful party political ideologies are nothing. Why did the energy crisis have to be ideological Reasons the nuclear power plants shut down affect us would have protected us from energy price increases? Why do you burden the industry with a supply chain law that… can only be followed at great cost? In the countries, Those affected by it have no effect. Listen daily we hear about new laws from Berlin or Brussels. An example from housing construction: How many building regulations are there? In Germany? The Association of Cities and Municipalities estimates 20,000, including 4,000 DIN standards alone. One reason why the construction industry is currently doing so badly. One Solution to many problems affecting our economy in all Areas that would be enormously burdened would be the entire body of legislation to clear out and downsize the Federal Republic. This would mean fewer officers would be needed to Monitor compliance with these laws. Many authorities are hopelessly overwhelmed!
Dismantling the mountain of legislation would cost the federal treasury to dramatically relieve the burden! You would like to have a company again to lead or become self-employed. The mood in the country would improve very quickly and it would be an incentive for the industry to invest and new to develop technologies.

CORELESS CURRENT SENSORS FROM SINOMAGS

As a subsidiary of the Sinomags Group, Sensitec has a comprehensive product portfolio of current sensors. This portfolio meets the requirements of a wide range of industries and applications and includes sensors for charging infrastructure, onboard chargers, leakage current sensors for photovoltaic systems, and broadband current sensors for modern drive technology. The product portfolio is divided into two areas: Module-level based current sensors for THT mounting on PCBs or with cable connection and chip-level based sensors that can be assembled as SMD components on the PCB. In addition to TMR technology, Hall or flux-gate sensor elements are also used as the underlying sensor technology. SMD chip sensors especially do not require flux concentrators (coreless current sensors) and are now able to reliably measure currents in the mA range.

• In addition, the SMD versions are available at a price range that also allows them to be used in price-sensitive applications. With SMD chip sensors, there are variants with an internal current path and variants in which the current path runs outside the housing. As no additional flux concentrator is used in either case, the sensor must be placed in immediate proximity to the current conductor, which requires innovative concepts for stray field rejection and isolation. This is achieved, for example, by differential measurement at two points with separate TMR half-bridge chips.
• The technical advantages of coreless current sensors compared to shunt solutions are the reduction in the size of the measuring system due to the elimination of peripheral circuitry and heat sinks, as well as lower primary conductor impedances and therefore lower heat generation with galvanic isolation.
• While the insulation to external conductors is easy to realize, the safe, reinforced insulation according to standard specifications is a challenge for compact IC housing solutions. The STK-616-M series sensors use a multifunctional PCB chip carrier made of BT material as an insulator, shielding, and wiring layer. A standard reflow soldering process can be used for processing.
• The STK-616 series offers high product flexibility in coreless current sensors through additional functionalities such as OCD (Current Detection) and filtering, as well as variants for high frequency ranges with a bandwidth of up to 2 MHz. Sensors with an additional measuring range for AFCI (Arc Fault Circuit Interrupter) detection, such as the STK-616TMWD, are also part of the Sinomags Group’s portfolio. This allows arcs to be detected as a cause of fire in PV installations, for example.

The latest product STK-616AM is equipped with extra-wide solder tags for the primary current, which also enables it to be used with higher currents of up to 100 A.

TIMING – WE HAVE THE HEARTBEAT OF YOUR APPLICATION FOR YOU!

n the dynamic landscape of precision engineering, where every microsecond counts, quartz crystals and oscillators emerge as the bedrock of cutting-edge timekeeping technology. The pivotal role these components play in synchronizing industrial processes and revolutionizing our understanding of timing accuracy is often overlooked, but it should not be. Leveraging the stable oscillation of quartz crystals, our industry has witnessed a paradigm shift in timekeeping precision. Quartz watches, long admired for their accuracy, owe their reliability to the consistent vibrations of these crystals, providing a robust foundation for applications that demand unfaltering temporal precision.

In the industrial realm, the integration of quartz technology extends beyond watches, influencing sectors ranging from telecommunications to aerospace. The inherent stability of quartz oscillation has become instrumental in calibrating and synchronizing a multitude of critical processes, ensuring that our industrial operations unfold with impeccable accuracy. Complementing quartz in this symphony of precision are oscillators, the unsung

heroes orchestrating the rhythmic pulse of our timekeeping devices. Oscillators are more complex timing systems with a great variety of specifications and technologies ranging from temperature to voltage-controlled oscillators. Meanwhile, the digital age witnessed the rise of microelectromechanical systems (MEMS) oscillators, revolutionizing electronic synchronization with their compact yet powerful design. In an era where efficiency is paramount, MEMS oscillators have found their place as indispensable components in modern electronics. From network synchronization to data processing, these semiconductor-based oscillators exemplify the pinnacle of precision engineering, enabling industries to operate seamlessly in our interconnected world. We at Endrich have the timing component that fits your application – from the classic quartz (oscillator) solution provided by our well-known partners Citizen, SMI, Chequers, or TaiSaw to the state-of-the-art MEMS-based solution by the pioneer and world market leader SiTime – contact us and we will find the perfect match for your needs.
