New male header series in sandwich construction with a grid pattern of 1.27 mm

Biometric sensor modules for global health projects

Prima Electronic Services has utilised its engineering experience and knowhow to help Cambridge-based start-up Simprints to produce the Vero 2. Simprints supplies fingerprint biometric sensor modules to countries including Tanzania, Ethiopia and Bangladesh. The modules provide the means to accurately identify people in places where forms of documentation are simply not available. In such situations, biometrics offer an effective alternative. When plans were formulated by Simprints’ engineering

team to produce the Vero 2, the decision was made to engage with Prima. The local support, plus exceptional responsiveness and technical expertise it could provide were all recognised as being highly beneficial to the project’s completion within a tight deadline. Prima and Simprints worked on rapidly finalising a fully

functioning prototype. Together, the two companies established a highly efficient automated test process. Once samples using the initial design had been made and tested, Prima implemented the required iterative changes. As Simprints’ operation is relatively small, most of the project’s main activities had to be outsourced. Prima therefore organised all the procurement, sourcing the complete bill of materials. In addition, Prima provided Simprints with useful guidance on potential supply chain issues, and helped to address these by suggesting modification to the design. Smiths Interconnect launches K-band waveguide

In order to ensure increased stability and secure contact with larger board-to-board spaces, Fischer Elektronik has created a new series of male headers in a sandwich construction with a grid pattern of 1.27 mm. For those new male headers which are offered in straight form for through-hole technology (THT), you can choose from six versions, each with two different heights and a clearance of 9.2 mm and 11.7 mm between the two insulators.

Those are the part numbers with the designations SLV W 6 092… and SLV W 6 117… for the 1-row, the SLV W 7 092… and SLV W 7 117… for the 2-row in grid pattern 1.27 x 1.27 mm and the SLV W 8 092… and SLV W 8 117… for the 2-row in grid pattern 1.27 x 2.54 mm. Those male headers are available with the number of contacts 1-36 for the 1-row and with the number of contacts 4-72 for the 2-row. The male contacts with a square pin cross-section of 0.4 mm are made of a copper-zinc alloy (CuZn) and receive a gold-plated or tin-plated surface coating, which is ideal for soldering, in our company Fischer Oberflächenveredelung (FOV).

In order to withstand the temperatures of 260 °C during the reflow soldering process, the insulating body is made of a high-temperature-resistant plastic which flammability is classified according to UL 94 V-0. This plastic achieves its good mechanical and dimensionally stable properties by the addition of fillers.

Furthermore, these materials have good flow properties and are therefore ideally suited for these devices. When designing and selecting the materials being used, Fischer Elektronik attaches great importance to making the products sustainable in accordance with EU Directive 2015/863 / EU (RoHS) and the requirements of Regulation (EC) No. 1907/2006 (REACH) to manufacture.

Embedded ARM Core Front Panel Solutions from ITRON (U.K.) LTD

Itron’s powerful ARM-9 based embedded TFT modules provide serial interfaces to link host and peripheral devices using USB, RS232, Async, SPI, I2C, CAN and Ethernet. Most ports double up as general I/O with IRQ functionality. Our embedded solutions allow design engineers to move application processing into the TFT module which reduces host overhead and enables easily manageable communication speeds. The host overhead can send raw data to the TFT module for the operating system to process and synchronise display refresh, navigation and peripheral control.

Pickering delivers clear, comprehensive new information resource

Pickering Electronics, the reed relay company which has pioneered miniaturization and high performance for over 50 years, has completely revamped the datasheets of its entire range of reed relays, providing more information in a clearer format with interactive links to further useful content. New information includes additional environmental specs, mechanical characteristics and relay weights, plus RF plots for coaxial relays, showing VSWR, isolation and insertion loss. Instead of being ‘squashed’ onto two pages – a legacy of printed datasheets - the specifications and relay details are more clearly laid out, especially the mechanical drawings. The new designed-for-digital datasheets include interactive links to relevant technical applications information and content, including a summary document entitled ‘10 key benefits of Pickering Reed Relays’ and a comparison table to similar products from Pickering. Comments Pickering CEO Keith Moore: “It’s easy to overlook so-called ‘simple’ components such as

reed relays, so we decided to make all our experience available to designers as easily as possible, so they make the correct choice.”

Pickering’s new reed relay datasheets are available to view and download at: Components in Electronics July/August 2021 47
