Pickering delivers clear, comprehensive new information resource


Interactive datasheets revealed - packed with more information – clear and easy to read 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.”

Reliable and accurate, even in harsh environments: Precision potentiometer 981 HE from Vishay


at Rutronik The 981 HE series operates using non-contact Hall-effect technology, making it particularly durable and able to withstand high vibration. Available with hollow or D-shaft as well as spring-loaded version, it offers precise linearity of up to ±0.5%, as well as excellent repeatability. The sensors are capable of


operating without limitations under conditions of high- frequency vibration up to 20G and shock up to 50G, and over a wide temperature range from -45°C to +125°C. The series also impresses with its simple mounting and high durability with approximately 10 million cycles. The high precision is ensured by nearly 360° scanning. It is perfect for foot pedal/throttle/steering/lift/shuttle/suspension system position sensors,


drive-by-wire, tilt control and tilt positioning feedback - used in marine and aerospace applications, agricultural and construction machinery, as well as in motor vehicles.

Lattice sensAI Solution Stack Simplifies Deployment


of AI/ML Models on Smart Edge Devices Supports TensorFlow Lite and Lattice Propel for Embedded Processor-based Designs; Includes New Lattice sensAI Studio Tool for Easy ML Model Training Lattice Semiconductor Corporation (NASDAQ: LSCC), the


low power programmable leader, today announced enhancements to its award-winning Lattice sensAI™ solution stack for accelerating AI/ML application development on low power Lattice FPGAs. Enhancements include support for the Lattice Propel™ design environment for embedded processor-based development and the TensorFlow Lite deep-learning framework for on-device inferencing. The new version includes the Lattice sensAI Studio design environment for end-to-end ML model training, validation, and compilation. With sensAI 4.0, developers can use a simple drag-and-drop interface to build FPGA designs with a RISC-V processor and a CNN acceleration engine to enable the quick and easy implementation of ML applications on power-constrained Edge devices. There is growing demand in multiple end markets to add support for low power AI/ML inferencing for applications like object detection and classification. AI/ML models can be trained to support applications for a range of devices that require low-power operation at the Edge, including security and surveillance cameras, industrial robots, and consumer robotics and toys. The Lattice sensAI solution stack helps developers rapidly create AI/ML applications that run on flexible, low power Lattice FPGAs. “Lattice’s low-power FPGAs for embedded vision and sensAI solution stack for Edge AI/ML applications play a vital role in helping us bring leading-edge intelligent IoT devices to market quickly and efficiently,” said Hideto Kotani, Unit Executive, Canon Inc.

www.cieonline.co.uk Omron launches efficient PWM


controlled power relays Omron Electronic Components Europe has launched PWM controlled versions of three of its most popular power relays offering coil power levels 75-90% lower than comparable standard versions. Omron G2RL, G5Q and G5NB relays are now available in types supporting pulse width modulation (PWM) of the coil holding current, reducing the duty cycle and hence the average current. This decreases the power consumption and hence the heat developed in the relay, improving efficiency and reducing thermal load. The high capacity 16A G2RL-PW1 features a coil power consumption of just 120mW, compared to 400mW for the standard version. The miniature 10A SPDT G5Q-PW has a coil power consumption of just 36mW in PWM form, compared to 400mW for the standard version. The 3A / 5A G5NB-PW offers the lowest coil power consumption of just 32mW, compared to 200mW for the standard model.

UK made: Pump maker buys Seaward


production tester Sunderland-based Salamander Pumps has turned to Seaward Electronic of County Durham for production line test equipment.


Salamander decided to move electrical safety testing into


post-assembly test while re-shaping its manufacturing operations to meet the needs of different pump types, some of which include electronics. The automated test solution it developed uses a Seaward


HAL 104 programmable tester to provide a suite of electrical safety tests and data traceability, integrated with a custom test jig with automated test connections.


When a pump assembly is located into the jig, pre-


configured codes automatically enable earth continuity and insulation tests, followed by a hipot (flash) test. Safety interlocks protect the operator. Automatic electrical testing is followed by pneumatic


testing to verify the integrity of the seals, then functional and performance testing. “We have worked with Salamander for a number of years,


and helping our customers integrate our products into bespoke production lines is a challenge that we are always happy to take on,” said Seaward application engineer Anthony Snowdon.

Redesigned Range of Compact, Piezo-Based Objective Positioning Systems. Focus on: High Dynamics, Large


Travel Ranges, and Improved Usability. PI (Physik Instrumente) has completely redesigned its portfolio of compact vertical positioners for microscope objectives – PIFOCs. Essential improvements are the higher dynamics, travel ranges to 800 µm, and a simpler handling. The PIFOCs, suited for integration in objective revolvers of upright as well as inverse microscopes, are important for applications in life sciences, materials microscopy, quality assurance, and the semiconductor industry. New P-725 piezo-based lens scanners from PI The new P-725 piezo-based lens scanners from PI were extensively redesigned. They are characterized by high dynamics, precision and usability. In addition to systems with 100 µm and 400 µm travel range, PI now also offers a system with 800 µm travel range. At the heart of the new PIFOC® portfolio are three systems that differ in their travel ranges: 100 µm, 400 µm, or 800 µm. Thanks to a few constructional changes, such as optimized levers and steel mounts, major improvements of the dynamic properties could be achieved. Additionally, for the first time a vertical positioner with an 800 µm travel range is also available. Simplified Handling The handling of the PIFOCs was also optimized. The new clamp ring only puts slight restrictions on the original focus displacement in the Z direction of the focus knob. For a lower number of variants, the largest possible diameter was chosen for the aperture. A set of adapter rings makes it easy to screw in different objectives of a size of up to M34. Small Bending Radii of the Cables and Improved Strain Relief The rotation, which is repeatedly carried out at the revolving nosepiece when changing the magnification, puts mechanical strain on the signal and current carrying cable. A new sheathing of the cable now makes much tighter bending radii possible; the new strain relief reliably prevents damage of the cable entry at the PIFOC® housing.
