172381 is an RF coaxial crimp plug connector with a 19 mm hex coupling nut, specifically designed for LMR/FBT-195 cable compatibility. The connector features a 50 ohm impedance with a frequency range of 0–6 GHz and maintains a VSWR of 1.2 (-20.828 dB) maximum across 0–4 GHz, ensuring excellent signal integrity. Key materials include a copper ferrule with white bronze plating, brass body with white bronze plating, gold-plated brass contacts, and PTFE insulators, providing robust performance across an operating temperature range of -65°C to +165°C with a dielectric withstanding voltage of 2500 VRMS minimum. The connector supports 500 mechanical durability cycles and accommodates crimped ferrule (hex crimp size 0.213") or crimped contact pin (hex crimp size 0.105") terminations, making it suitable for demanding RF applications in telecommunications, aerospace, and industrial instrumentation where reliable high-frequency signal transmission is required.
