You probably don’t know it, but you’ve been referring to most D-sub connectors incorrectly for your entire career. Here’s how to get them right, but you’ll be speaking a language that few understand. D-Subminiature (D-sub) connectors, you find them in consumer PCs, industrial equipment, and even in networking equipment. They’re everywhere and manufactured by many […]
What is the common impedance of a twisted pair?
Understanding impedance in twisted-pair cables help you avoid signal problems.
The connector is often the EMI problem
It only takes 3µA of current to fail an EMC test, and a connected can produce that much.
D-sub connectors: Most get them wrong
Designation Number of pins (normal or high-density) Example configuration DA 15 or 26 DB 25 or 44 DC 37 or 62 DD 50 or 78 DE 9 or 15
Call for abstracts: Printed/flexible stretchable and functional fabric sensors
Roger Grace Associates has announced the call for abstracts covering medtech/wearable applications for a full-day symposium preceding the Sensors Converge conference. Both the symposium and conference will take place at the McEnery Convention Center in San Jose, CA. The pre-conference symposium will address printed/flexible stretchable (P/F/S) and functional fabric (FF) Sensors and electronics from a […]
Keysight’s Innovation Challenge is back for 2022
The student competition for IoT designs to mitigate climate change and reduce energy consumption is back on track for 2022. Registration opens April 4. After a two-year COVID-19 hiatus, Keysight Technologies has rebooted its IoT Innovation Challenge. The Keysight Innovation Challenge 2022 student competition challenges students to design IoT devices that sense our world and […]
Liquid crystal polymers get an upgrade for sigh-speed signals
RF and high-speed digital signals have brought on the development of new liquid crystal polymer materials used in connectors, PCBs, and other interconnects. Liquid crystal polymers (LCPs) are experiencing a surge in demand resulting from high-speed communications technologies, particularly fine-pitch components such as high-frequency connectors, board-to-board connectors, and low-pass insulation supporters, or dipoles on active […]
RTD probes come in 3-wire and transmitter models
Tel-Tru Manufacturing has introduced an advanced line of 3-wire industrial RTD assemblies and temperature transmitters. These probes are designed for the applications common to food and pharmaceutical processing, refineries, chemical plants, water and wastewater facilities, breweries, dairies, HVAC, and the OEMs serving them. The temperature transmitters provide 4-20 mA or HART outputs. Standard RTD assemblies […]
