RF Connectors’ P2RFD-1660-SS low-loss, low VSWR precision large-format 50 ohm interface adapter with a stainless steel coupling nut is mated directly to the test port adapter to increase its life when testing 7-16 DIN connectors and assemblies. After carefully installing the P2RFA-1660-SS on the test port, hundreds of tests, even PIM testing (requiring greater torque per test to ensure proper ground) can be performed before wear requires replacement. The adapter is machined to exacting specifications with a white bronze plated body and stainless steel coupling nut for tarnish-free service.
