High-speed data transfer Twisted pairs connectors

Precision modular connectors to suit your application LEMO’s Original Push-Pull connector range fulfils most specific & stringent requirements for many market segments, including but not limited to Test & Measurement, Industrial, Automotive, Semi-conductor, Medical, Aerospace & Defence. Constantly upgraded with the latest technologies since LEMO’s invention of the Push-Pull connector (patented), it has been the trusted solution to build long lasting, safe and high precision interconnect solutions for more than 75 years. Its highly recognizable chocolate design pattern represents the LEMO brand...

High-speed data transfer introduction Equipped with more and more sensors, objects, vehicles and machines are more and more communicating with each other and with the outside world thanks to the emergence of the Internet of Things (IoT). The reliable transfer of more and more data in the shortest possible time is becoming increasingly important. High-speed data transfer can be achieved with different cable technologies, mainly twisted pairs ➀, coaxial ➁ and fibre optic ➂ cables. Environmental conditions, distance, cost and application are key decision criteria to select the appropriate cable...

LEMO’s USB 3.1 connectors are meeting the stringent requirements of the USB protocol for High-speed data transfer up to 10 Gb/s. These products are specifically designed to work in demanding environments (e.g. extreme temperature, high humidity, vibration) for applications such as industry, food processing, industrial automation, technical equipment in buildings, data communication, defence and instrumentation. While using a proprietary interface guaranteeing high quality signal within a very robust casing, the LEMO connectors can be used in conjunction with standard USB type interfaces (e.g....
