Adapter RP-SMA Female To RP-SMA Female: Waterproof O-Ring Bulkhead


In stock
0.02 LBS
  • RP-SMA female on both sides: One side has a large-sized bulkhead nut (outer diameter of the nut is 12.70mm) - much larger than the standard bulkhead for RP-SMA. 
  • A red O-ring is included, to make a waterproof seal in the port of a enclosure or panel
  • The thicker middle section (where the bulkhead nut resides) has a flat element to prevent turning while inserted in the panel (known as "d hole")
  • Enables connection / coupling of two RP-SMA male connectors: Bulkhead Feedthrough Adapter.
  • Impedance: 50 Ohms
  • IP68 waterproof rating.

Through-Hole Mount / Feedthrough Adapter, with bulkhead nut and washer, and O-ring. This is a cable-coupling/coupler that feeds through an enclosure wall, for example.

Brand new, gold-plated, high quality connector from ISO 9001 facilities. Lead-free and ROHS compliant. The O-ring is silicone.

RP-SMA female & hex-nut specs / diameter:

  • Hex nut accommodates a screw/bolt with 5/16" nominal outer diameter
  • In other words, the inside diameter of the hex bolt is 5/16". RP-SMA male inside diameter is 5/16"
  • Outer diameter of the hex-nut is 12.70mm. 
  • If you need to cut a hole for this adapter: The diameter of the RP-SMA-female (including threads) is 6mm.  
  • If you need more detailed specs please contact us.

RP-SMA is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz: This antenna cable is compliant for all types of wireless antennas, including WiFi & WiMax networks: 802.11N, AC, G, A, B. 900MHz, 2.4GHz & 5GHz applications, as well as any other frequency between 0 and 18GHz.

RP-SMA connector composition:

  • Center Contact: Beryllium Copper, Gold Plated
  • Connector Body:
    • All the cables on this page that are made with 400-series coax have connectors that are nickel-plated brass (on the connector body).
    • All the cables on this page that are made with 200-series coax have connectors that are gold plated brass (on the connector body).
  • Crimp Ferrule: Copper, Nickel Plated
  • Insulators: PTFE

Connector fits items that have a (male) RP-SMA (Reverse Polarity [RP] SMA) jack/connector. RP-SMA = Reverse Polarity SMA.

Data Alliance's high-quality soldered terminations of RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

GENDER DETERMINATION: Gender of RP-SMA is counter-intuitive in two ways:

  1. The gender is referring to the pins inside-not the threads. RP-SMA female has threads on outside.
  2. "RP" stands for reverse polarization: The pins are female when they appear to be male, and vice versa.
