Highly versatile modular connector system from Positronic in stock at Powell Electronics
Positronic Scorpion series: 35+ modules offer nearly limitless pin configurations. Available through Powell Electronics, the supplier of
connectors and more for high-rel applications including defence, aerospace and industrial, is the highly versatile Scorpion modular connector system from Positronic. The components can be configured for use as power connectors (16A up to 120A), signal level connectors or as a combination of the two in an almost endless variety of power/signal contact configurations. The unique modular tooling provides multiple keying options, yet still provides a one piece insulator for use in the finished connector. Positronic’s Scorpion series includes 35+ modules available in standard profile (14.6mm height) and low profile (8.2mm height) versions. Blank module options allow design engineers to space power and signal contacts to meet creepage and clearance values required for specific applications. The Scorpion series includes board-to-board, cable-to-cable or board and panel-to-cable or board
versions. An outlet hole enables air cooling onto a power contact. Termination options are solder PCB mount, crimp and press-fit. Available mating alternatives are blind mating, float mount, panel mount and cable connector with a unique locking system. The precision formed and solid machined contacts feature shielded, high voltage and hyperboloid contact versions.

New high voltage SIL/SIP reed relays from Pickering Electronics feature higher coil resistance for low power consumption
3kV stand-off; mu metal screening to enable close stacking. Pickering Electronics, the reed relay company which
has pioneered miniaturization and high performance for over 50 years, announces the Series 100HV high voltage SIL/SIP reed relays rated for up to 3kV stand-off voltage and with more than double the coil resistance of previous devices. This suits applications such as transformer or cable testing or any other automatic test equipment where high voltages are involved but where low coil power consumption is required. Commented Kevin Mallett, Technical Specialist at
Pickering Electronics: “Where mains voltage is switched, for example to control and isolate SCR or triac gates, Series 100HV reed relays are an ideal choice. And in mixed signal applications, the lower coil power of the new relays reduces the thermal EMF voltages generated across the switch.” Three types of dry switches are available, capable of standing-off 1.5kVdc, 2 kVdc or 3kVdc. The 3 kV version features increased clearance between the switch and coil pins to accommodate the higher voltage. Higher voltage versions are available on request. Series 100HV reed relays feature an internal mu-metal screen to facilitate close stacking without risking problems caused by magnetic interaction. The new high voltage SIL/SIP reed relays are available with one or two switches in a single package
in 1 Form A, 2 Form A and 1 Form B configurations. 5V, 12V or 24V coils with optional internal diode can be specified.

Power Integrations Introduces SCALE-iFlex Single Plug-and-Play Gate Drivers for “New Dual” Modules s
SCALE-2 technology optimizes footprint, improves efficiency, performance and reliability of power inverters and converters to 3300 V. Power Integrations (Nasdaq: POWI), the leader in gate-driver
technology for medium- and high-voltage inverter applications, today announced SCALE-iFlex™ Single gate-drivers for the popular “New Dual” 100 mm x 140 mm IGBT modules. The compact new drivers support modules up to 3.3 kV and are available now for design-in. The SCALE-iFlex Single gate-drivers are ideal for light-rail, renewable energy generation and other high-reliability applications that demand compact, rugged driver solutions. Thorsten Schmidt, product marketing manager at Power Integrations commented: “SCALE-iFlex Single
gate-drivers fit the outline of the latest standard IGBT power modules including the Mitsubishi LV100/HV100, Infineon xHP2 and xHP3, ABB LinPak, Hitachi nHPD² and other similar products.“ SCALE-iFlex Single gate-drivers use Power Integrations’ SCALE-2™ ASIC technology which dramatically
reduces component count compared to conventional products. The ASIC also provides Advanced Active Clamping (AAC) over-voltage protection during normal operation, a substantial improvement over simple soft shut down, which adds extra protection in case of short-circuit during turn-on. Devices are conformally coated and feature reinforced isolation. Isolated housings ensure isolation between modules when they are mounted side-by-side. Devices are pre-qualified according to railway standards IEC 61373 – Class 1B (shock & vibration) and IEC 61000-4-x (EMC tests) and IEC 60068-2-x (serial environmental tests). Burn-in is optionally available.
The new gate drivers are rated at 20 A peak output current per channel at 85 °C ambient temperature with no air flow. Higher power levels are possible with cooling or a lower ambient temperature. Both electrical and fiber-optic interfaces are available.

Now you can send a selfie from anywhere: MIKROE adds Wi-Fi 8 Click to growing family of Wi-Fi peripheral development boards
Based on Microchip’s highly integrated low power Wi-Fi and Bluetooth module. MikroElektronika (MIKROE), the embedded solutions company that dramatically cuts development
time by providing innovative hardware and software products based on proven standards, has launched WiFi 8 Click a compact add-on peripheral board that features Microchip’s ATWINC3400-MR210CA Wi-Fi and Bluetooth 5.0-certified module that is optimized for low power and high-performance mobile applications. WiFi 8 Click joins 15 other Wi-Fi clicks available from MIKROE, and the total number of Click peripheral development boards offered by the company is now well over 1000. Nebojsa Matic, CEO at MIKROE explains why so many Wi-Fi Click variants are available: “Wireless communication is essential for all aspects of life today. Yet different environments and applications require different Wi-Fi chips and modules. If you have a Wi-Fi router connected to a fixed broadband line, Liechtenstein has the fastest Wi-Fi speeds in the world at 229.98 Mbps, according to
Cable.co.uk data. Even on Everest there is Wi-Fi, at least at base camp. Whatever the need, bringing mobility and internet to your design is just a Click away.” The Wi-Fi 8 Click board costs just $34.00, suiting it to highly integrated and cost-effective applications, industrial wireless control, Bluetooth gateway, smart home applications, and much more. The module comes with integrated power and low-noise amplifiers, transmit/receive switch (for WiFi and Bluetooth), a power management unit, an integrated 2.4GHz chip antenna, and an additional 32.768 kHz clock for Sleep operation.

Trackwise to show length unlimited multilayer flex printed circuit technology at DSEI 2021
Trackwise, the AS9100D accredited innovative UK designer and manufacturer of specialist interconnect solutions using printed circuit technology, will demonstrate the massive advantages that its patented Improved Harness Technology™ (IHT) can bring to defence applications at the Defence and Security Equipment International (DSEI) exhibition which takes place 14-17 September at London’s ExCeL. IHT from Trackwise uniquely enables multilayer Flex Printed Circuits (FPC) of unlimited length to be constructed. The resulting interconnect solutions replace multiple wires with a single FPC, saving weight and space, and increasing flexibility, reliability and repeatability while reducing assembly time. Already the company is developing multiple IHT interconnect FPCs for numerous aircraft and other
defence applications, designed and produced at the company’s UK facilities in Tewkesbury. Philip Johnston, CEO of Trackwise comments: “Light weight and small size are often critical for aircraft applications, and our IHT flex printed circuit technology is enabling new designs that would have been impossible with traditional wire harnesses.”
