Compact design for harsh environment

New multi coaxial model with high frequency performance

HARSH
ENVIRONMENTS
YOUR RUGGED SOLUTIONSLEMO is expanding its field-proven M Series with a new multi coaxial configuration, named LM.232,
available in size LM with up to 12x coaxial contacts. These new plugs and fixed sockets have been
specifically designed for all applications requiring high frequency performance in harsh environments.
This new insert configuration integrates 12x coaxial contacts type 0R (50 Ohm) allowing a frequency
up to 26.5 GHz with a low Voltage Standing Wave Ratio (VSWR).
The coaxial contact is easy to mount, thanks to its crimp contact and retaining clip. It is designed to beterminated with flexible low-loss communication cable LMR-100A or MULTIFLEX 86.
Typical applications are wireless network 5G wireless networks, radar systems, battlefield communications or UAV anti-drone technology, essentially any system where space saving and easy disconnection may be required.

Typical assembly of coax contact (Coax types—RG-174/U, RG-188 A/U, RG-316/U, LMR-100A, MULTIFLEX_86) = Cable Group 1
Coax contacts: Fit the crimp ferrule onto the cable. Crimp the central contact using tool DPC.91.701.V fitted with positioner DCE.91.050.RVCM, set toposition 3. Fit by turning the coax sub-assembly on the central contact until the stop is reached, check that the central contact is in the correct position
in relation to the sub-assembly (0.5 mm), fold back the cable screen, place the crimp ferrule over the crimping area and complete the crimp using toolDPE.99.003.1K.
