Called Optima D Series is sealed to IP68 (20m/2h) even when unmated, and complies with MIL-STD-810H for shock and vibration.
“D series connectors are compact with push-pull latching designed for tactical communication in military, aerospace, security and UAV applications,” said the company. It “is a commercial off-the-shelf product, that exceeds soldier battlefield MIL-STD-810 requirements”.
Two sorts of latching are offered: ‘break-away’ where the connector can be released by tugging on the cable, and ‘push-pull’ where tugging on the cable will not un-mate the connector and release is through pulling back the metal sleeve.
There are three standard (more optional) key patterns to avoid mating the wrong pairs.
Plugs and free cable sockets in the series have to be over-molded, for which the company offers a service along with cable selection, assembly and socket PCB design support.
With over-mold, the connectors are 25% shorter than Lemo’s earlier T Series, said the company.
Versions with up to 32 contacts are available in five diameters (panel cut-out = 7.1, 9.1, 12.1, 15.1 or 18.2mm). At the cable end, the size 0 (up to 12 circuit) version is 9.5mm in diameter, as an example.
Both mating halves can be specified with male or female contacts depending on safety requirements.
Mating endurance is at least 5,000 cycles and operation is over -55 to +150°C (chassis socket) or -40 to +90°C (plug and free socket).
The bodies are nickel-plated brass and salt fog endurance at least 1,000hr.
Various connectors support various signals including: 50Ω 15GHz coax, 75Ω coax, USBs 2.0 or USB 3.2 (10Gbit/s) and various Ethernets: 10G Base T1 single-pair, 10G Base T4, 1,000 base T1 or 1,000 base T4.
Screening is 360°, rated at >75dB up to 10MHz and >40dB up to 1GHz.
