EMC Products

EMC filter suits machinery and robotics

Schaffner has introduced the FN3271 filter which is designed to offer a compact, lightweight solution requiring minimum mounting space. With enhanced performance the filter suits EMC challenges where impedance at the connection to the noise source is high (>100ohm).

Industrial applications include variable speed electrical power drive systems, motor drives and systems containing frequency inverters and servo drives.

The filters meet EN 61800-3/A11 and performance is guaranteed under full load operating conditions. Solid, touch-safe terminal blocks are fitted to all models from 10 to 100A, offering sufficient contacting cross section according to EN 60204-1.

To improve installation safely, optional transparent protective covers are available for all filters with busbars from 150 to 1000A. These provide protection to the installer, operator or inspector by avoiding accidental contact with live conductors. The protective covers can be retrofitted after the filter is installed and connected.

Enclosure targets IoT/IIoT

OKW’s new Smart-Panel enclosures are designed to provide an elegant, robust and quick to install solution. Options include EMC shielding.

The enclosures are engineered for intelligent building control and monitoring in industrial, commercial and residential applications including IoT/IIoT, building services, electrical installations, communications, measuring/control and security.

To aid installation, the top snaps into place with no visible fixing screws. It can be re-opened using a set of push-in opening tools. The large, recessed top can accommodate LEDs, displays or a membrane keypad. A touchscreen can also be fitted.

The bottom section fits standard flush-mounted/cavity wall boxes (max opening 61mm) and larger international installation boxes (up to 150mm by 61mm).

The enclosures are 21.3mm deep and available in two plan sizes: 84 by 84mm and 155 by 84mm. They are moulded from tough, UV-stable ASA+PC-FR (UL 94 V-0) with a polished bottom section and a fine-textured top. The standard colour is traffic white (RAL 9016). Prices start at £18.

Common-mode filters for high-temp auto 

TDK announced the KCZ1210AH series miniaturized common-mode filters for automotive applications. Measuring 1.25 by 1.0 by 0.5mm, it contributes to a smaller footprint while providing a noise control function for different transmission signal lines for automobiles.

With an increase in advanced driver-assistance systems (ADAS) there is increasing demand for cameras which use common-mode filters as anti-noise products. However, as the conventional multilayer common-mode filter offers a temperature range of -40 to 105℃, it cannot be used for ADAS cameras. 

TDK’s series uses proprietary materials and structural design to offer a temperature range from -55 to 125℃. By featuring a conductive resin-based electrode, it controls product cracks due to thermal shock and increases durability against mechanical stresses, such as substrate strains. 

TDK is working to enhance its inductive devices for ADAS and will expand its line of miniaturized common-mode filters supporting higher-speed differential signals. Mass-production of this series began in September 2021.
