MX BNC Connector Terminator Metal Pin Gold Plated (MX-283)

Terminating an open BNC port matters for the same reason as any coaxial terminator - an unterminated port can cause signal reflections that distort a reading elsewhere in the same test setup - but this version steps up the build quality with a full metal body and gold-plated pin instead of the lighter plastic construction some economy terminators use. The metal body stands up better to repeated handling on a busy test bench, and the gold plating resists the contact degradation that a bare or tin-plated pin develops after enough screw-on/screw-off cycles. For a terminator that's going to live on a frequently-used piece of test equipment rather than sit untouched on an installation, the sturdier build is worth the small price difference.
