031-6861 is a BNC crimp plug connector designed for LMR-240 cable assemblies, manufactured by Amphenol RF. The connector features a 50 ohm impedance with a frequency range spanning DC to 12.4 GHz, delivering return loss (VSWR) of 1.20 maximum from DC to 4 GHz and 1.30 maximum from 4 to 12.4 GHz. The connector is constructed with phosphor bronze body (nickel plated), brass shell and ferrule (nickel plated), gold-plated brass contacts, and PTFE insulation, providing excellent durability with a minimum of 500 mechanical cycles and operating temperature range from -65°C to +165°C. With a dielectric withstanding voltage of 1500 VRMS minimum, this connector is ideal for RF/microwave applications requiring reliable high-frequency signal transmission in demanding environments.
