Product details

RP-TNC Plug for RG-8X and LMR-240 — 50 Ohm, 11 GHz

The Amphenol 122408RP is an RP-TNC (Reverse Polarity TNC) plug with a female socket centre contact, designed for crimp termination onto RG-8X, Belden 9258, and LMR-240 cables. It ships as a complete crimp kit: one connector body, one contact, one ferrule, and one insulator.

This plug is built for three specific cable types: RG-8X, Belden 9258, and LMR-240. All are 50 Ohm cables, common in Wi-Fi, ISM-band, and land-mobile installations.

500 Mating Cycles — Threaded Reliability

The nickel-plated brass body resists corrosion in outdoor enclosures; the gold-plated centre contact maintains low contact resistance across those 500 cycles.

Frequently asked questions

Is 122408RP a male or female connector?

The 122408RP is a plug with a female socket centre contact — it is the cable-end connector that receives a male-pin RP-TNC jack.

Can 122408RP be used with LMR-240 cable?

Yes, LMR-240 is one of the three cable types listed for this plug, alongside RG-8X and Belden 9258.

What is included in the 122408RP package?

The bulk package includes four pieces: one connector body, one centre contact, one ferrule, and one insulator — a complete crimp kit for one termination.
