Lemo puts 10Gbit USB 3.1 and 1Gbit/s single

Jun 08, 2023

Lemo has developed USB 3.1 version of its push-pull latching connectors for use up to 10Gbit/s.

They are available in the company's B, K and T series (see table) for demanding indoor and outdoor environments, for applications in defence, industrial automation, data communication, aerospace, test and measurements.

There are nine connections: two separately shielded high-speed pairs (with a common shield connection) a power pair and a legacy USB 2.0 pair.

At the same time, it announced a connector pair for IEEE 802.3 single-pair Ethernet (‘SPE’ or ‘1000Base-T1’) for vehicle and industrial use.

"The emergence of single-pair Ethernet is now driving the adoption of Ethernet in the automotive industry as well as in industrial automation," according to the company. "1000Base-T1 is designed to operate over a single twisted-pair copper cable, supporting an effective data rate of 1Gbit/s in each direction simultaneously. These products are specifically designed to work in demanding environments, for example: extreme temperature, high humidity or high vibtation."

There are two types of insulator: 0B.511 (~9.5mm dia, two contact) and 1B.512 (Not shown, ~12mm diameter, four contacts + three contact in a line between them forming a screen). Both are compatible with un-shielded twisted pair and shielded twisted pairs, Lemo told Electronics Weekly.

These also come in B, K or T Series, and add to similar earlier connectors for Cat 5e, Cat 6 or Cat 6a.
