The Lemo FFA.00.250.CTAC29 is a single-contact coaxial plug connector engineered for high-density instrumentation and laboratory systems requiring reliable RF interconnections. This straight plug delivers 50 Ω impedance performance with push-pull locking, rated to 4 A and 3000 V DC, making it suitable for demanding test and measurement environments. The connector features a chrome-plated brass shell with nickel-plated brass latch components, achieving >90 dB shielding at 10 MHz and >70 dB at 1 GHz. Solder termination on both conductor and screen cable collet ensures secure mechanical and electrical integrity across 5000 mating cycles. Temperature range spans -55 °C to 250 °C with salt spray corrosion resistance exceeding 1000 hours, meeting CD/N 549 NIM-CAMAC specifications.
