Thin magnetic sheets have high permability for NFC

Wed, May 17, 2023

Noise suppressing / magnetic sheets by TDK have high permeability and low magnetic loss for NFC (near field communication) applications. The IFQ06 thin magnetic sheets are flexible and can be easily formed to a desired shape, said the company.

The sheets are suitable for 13.56MHz NFC applications and protect the system from metal objects located directly behind coils.

The latest addition to the Flexield family of magnetic shielding materials, the IFQ06, has high permeability and low magnetic loss, said TDK and provides highly effective protection against performance-reducing design features that can complicate NFC designs, such as metal objects directly behind the antenna.

These hazards are becoming increasingly common as electronic devices evolve to be smaller and more multi-functional, making it increasingly difficult to keep advanced functionalities from interfering with each other. NFC uses electromagnetic induction where the antenna receiving a carrier wave from a reader / writer allows the on-board IC chip to perform signal processing.

Metal objects, in particular, can absorb or disturb the magnetic flux lines of the generated H field, creating eddy currents which reduce effective range. These disturbances can also shift the inductance value and self-resonance frequency, reducing performance because of tuning issues between the two antennas. In some cases, metal close to the antenna will carry an induced current that produces a countering magnetic field, shortening the communication distance and making communication impossible.

Placing the IFQ06 material between the antenna coil and any metal surface confines the magnetic flux within the magnetic shield generated by the reader / writer. As a result, the generation of an induced current on the metal surface is eliminated and optimum 13.56MHz communication conditions can be maintained.

TDK lists other benefits of the IFQ06 series as its ability to shape / direct the magnetic H field, influence the quality factor (Q) of the inductive antenna, increase the coupling factor (K) between two antennas, help set the inductance value (Ls) for resonant tuning, complete the magnetic field path and to improve security by encapsulating the magnetic field and its respective information.

TDK’s IFQ06 flexible magnetic sheet materials are offered in a choice of three formats: roll or sheet materials for prototyping, lower volumes or where large areas need to be covered and custom cut parts which exactly match design requirements for higher volume or automated assembly options.

Standard thicknesses available are 0.05, 0.1 and 0.2mm. Thicknesses of 0.065 and 0.075mm are available on request.

High surface resistivity is above 10 MOhm allowing for direct contact to metal antennas.

The material is available with an optional high temperature resin [IFQ06S] that supports applications up to +125 degrees C.

Pre-assembled connectors plug in to automation trends

Tue, May 02, 2023

Mobile machinery in agriculture and construction challenges automation specialists, said binder. The increasing degree of automation, agricultural and construction machinery is becoming a more and more important field of application for advanced sensors and actuators. They are used for inclination, position, or level detection, but also for actuators or valve controls.

Furthermore, displays, lighting, operating devices, and diagnostics modules have to be connected within the mobile machines, such as tractors and their attachments to combine harvesters and crop choppers to excavators, cranes, or dump trucks. The safe and fast connection of automation components is becoming immensely important, said binder.

Proven technologies, such as Deutsch DT or AMP Superseal, meet automation components and binder provides industrial circular connectors that are ready to connector for the Deutsch DT, AMP Superseal and AMP CPC model series. These, in combination with connectors from the binder portfolio are part of its Plug&Play product selection, together with connectors pre-assembled with cables also available if required.

Cable switches with wiring options tailored to different applications enable connector systems of different designs to be combined in order to customise connectivity for mobile machines. For customers, this range can reduce the cabling effort and ensure a tamper-proof design, said binder.
Connector types such as the Deutsch DT, and the Superseal and CPC series from the manufacturer AMP have become established in such agricultural applications. The international standard for agricultural technology, ISOBUS according to ISO 11783, also defines certain interfaces in this market sector.

Integrating advanced sensor/actuator technology with the industry-proven connection technologies is a key challenge for machine engineers.

In order to ease this task for system integrators, binder offers both Deutsch-DT, and AMP Superseal and CPC connectors as part of its Plug&Play portfolio, in addition to its own series. This provides the user with the ability to combine a wide variety of connector types as needed. The products for agricultural and construction machinery meet IP67 protection degree requirements when mated. They are equipped with a process-safe cable overmould to relieve the wires from tension forces. The connectors are suitable for use on moving assemblies, with designs which feature cables suitable for power track chains.

To meet individual designs, tailored to the respective field of application, binder’s Plug&Play portfolio allows various connector systems – in overmoulded form – to be combined to create customised solutions. This already applies to quantities as low as one. Since splitter cables are often in demand in addition to simple patch cables, the range also includes cable switches with a wide variety of wiring options.

The binder Plug&Play portfolio offers the possibility to realise overmoulded Y distributions with ratios of 1:2, 1:4, 1:6 and 2:6. Users can choose the connector types. The variability of connection provides them with a wide range of options. The maximum possible pin counts vary, depending on the distribution ratio, between eight and 18. Cable diameters range from 3.5 to 10mm and the largest possible wire gauge is either 0.5mm² (1:2) or 1.0mm².

Buck-boost non-isolated DC/DC converters are rugged for AGVs

Fri, Apr 28, 2023

Rugged, non-isolated DC/DC converters with a wide range input and outputs make up the RGC series by TDK-Lambda.

The 300W DC/DC converters have an input voltage of 9.0 to 53V and deliver output voltages that can be adjustable from 9.6 to 48V or 5.0 to 28V with output currents of up to 12.5A.

The series is designed to be used in harsh environment applications including robotics, AGVs (automated guided vehicles), communications, COTS, industrial and portable battery-powered equipment.

They are supplied in a 1/16th brick form factor, measuring 38.1 x 49.5 x 13mm. The converters are encapsulated to provide a higher resistance to shock and vibration with qualification to MIL-STD-810G. The five-sided aluminium die cast housing with mounting tabs reduces radiated EMI and enables conduction cooling to a cold-plate for fanless operation, added TDK-Lambda.

The RGC models offer two voltage and current combinations to support operation from 12V, 18V, 24V, 36V and 48V batteries and power sources. The buck-boost topology allows the converter to maintain regulation even when the output voltage exceeds the input. When the converter is placed in standby using the remote on/off, the input current can be reduced to 0.25mA to conserve the battery charge. TDK-Lambda pointed out that wide input ranges simplify inventory management because one part number can cover multiple input and output voltages.

With efficiencies of up to 97 per cent, power losses are minimised allowing the products to operate in harsh environments with case temperatures of -40 to +115 degrees C. The basic feature models include an output voltage adjustment pin, negative logic remote on/off, remote sense, input under-voltage, over-current and thermal protection.

All models carry the CE and UKCA mark for the Low Voltage and RoHS Directives and are designed to the IEC/UL/CSA/EN 62368-1 safety standards.

Evaluation boards are also available for quick and easy testing.

TDK was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products.
