LEMO K-Series

PUSH-PULL CONNECTOR IDEAL FOR OUTDOOR USE

LEMO K-Series connectors have been specifically designed for outdoor applications. They include an inner sleeve and two seals to prevent penetration of solids or liquids into the housing, which is formed by the plug, free socket, fixed socket or coupler. All models of this series are waterproof and watertight when mated to give a protection index of IP68 as per IEC 60529 standard (in mated condition), when correctly assembled to an appropriate cable (IP66 in unmated condition). PEI-Genesis builds LEMO K-Series connectors from component parts and can configure thousands of unique connectors.

FEATURES

LEMO K-SERIES FEATURES

K-series connectors use the same contact arrangements and insulators as the B series
and have the following main features:

Security of the Push-Pull latching system

Solder, crimp or print contacts (straight or elbow)

Multiple key options to avoid cross mating of similar connectors

360 degree screening for full EMC shielding

Multipole types 2 to 64 contacts

High packing density for space savings

Keying system (G key standard) for connector alignment

Rugged housing for extreme working conditions; watertight connection (IP 68/IP 66)
