ORIGINALS B Series Connectors

LEMO's ORIGINALS B Series Connectors are keyed, multipole, and hybrid connectors that are ideal for instrument applications across many markets. The Push-Pull latching mechanism provides a secure connection, while the density of the contacts offers panel space savings. Multi-key options prevent cross-mating of similar connectors within a panel. Contact types include LV, fiber optic, HV, coax, as well as hybrid versions. LEMO's B Series Connectors have a temperature range of -55°C to +250°C and rugged housing for extreme working conditions. These connectors are used in medical, semiconductor, audio, video, aerospace, and transportation industries.
