LEMO FFA.00 to LEMO FFA.00 Cable

The LEMO FFA.00 to LEMO FFA.00 cable assembly delivers high-density signal and power transmission in compact form factors. Push-pull self-latching connectors enable quick mating and unmating with minimal footprint intrusion. The coaxial design maintains 50 Ω impedance across signal paths, making it suitable for RF and precision measurement applications. Chrome-plated brass housing with nickel-plated latch components ensures durability in demanding environments. Rated for 5000 mating cycles and operational from −55 °C to +250 °C, this assembly is purpose-built for nuclear physics instrumentation, medical devices, and test equipment requiring signal integrity and mechanical reliability.
