Product details

50 Ohm MMCX Right-Angle Plug for RG-178B

It is a right-angle, free-hanging (in-line) connector using a snap-on fastening mechanism, with the center contact soldered and the shield crimped.

This plug is designed specifically for RG-178B cable, a 50 Ohm, low-loss, double-shielded coax with a stranded centre conductor and FEP jacket, often used in tight-bend, high-density RF harnesses. The right-angle body keeps the cable exit parallel to the mating axis, saving space in enclosures where a straight plug would interfere with the lid or adjacent components. Termination is a two-step process: solder the centre pin to the cable's centre conductor, then crimp the shield ferrule over the braid.

Frequently asked questions

Where can I buy the MMCX-LP-178B/U available via RFQ confirmation?

The MMCX-LP-178B/U is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quote — submit an RFQ for your required quantity.

What cable group does MMCX-LP-178B/U support?

The MMCX-LP-178B/U is designed for RG-178B coaxial cable, a 50 Ohm, double-shielded type with a stranded centre conductor.

Is MMCX-LP-178B/U compatible with RG174 cable?

No, the MMCX-LP-178B/U is specified for RG-178B cable only. RG-174 has a different dielectric diameter and braid coverage, so the crimp ferrule and centre contact dimensions will not match.

What is the impedance rating of MMCX-LP-178B/U?

The MMCX-LP-178B/U is rated at 50 Ohms nominal impedance, matching the standard for most RF systems including wireless and GPS applications.
