LEMO T Series Connectors

LEMO T Series Connectors are specifically designed for use in outdoor applications. They include an inner sleeve and seals to prevent the penetration of solids and liquids. T series connectors are capable of becoming watertight when mated to give a protection rating of IP68 per IEC 60529 standards.
