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

Adapter SMA Female To SMA Female

• Introducing the SMA Female To SMA Female Adapter: It is SMA female on both sides. One side has a large bulkhead nut (the outer diameter of the nut is 12.70mm)—much larger than the standard bulkhead for SMA.
• A red O-ring, a testament to our commitment to reliability, is included to create a robust waterproof seal in the port of an enclosure or panel, ensuring the utmost protection in any weather conditions. Gold-plated and Nickel-Plated Options: Nickel-Plated Brass is the most corrosion-resistant of all plated brass alloys (better than gold-plated).  
• A second nickel-plated version has a Delrin (white plastic) cap for the flange so it will not contact a metal surface: Part# SfSfOP.
• The thicker middle section (where the bulkhead nut resides) has a flat element to prevent turning while inserted in the panel (known as a "dhole")
•  50 Ohm impedance
• IP68 waterproof rating
• Enables connection/coupling of two SMA male connectors
• ORING is UL-listed.

 

Through-hole mount / Feed through Adapter, with bulkhead nut, washer, and O-ring. This cable coupling/coupler feeds through an enclosure wall, for example.

Designed for Versatility: Our SMA adapter is compatible with many wireless applications, from Cellular LTE/4 G to IoT wireless, automation, and M2M.

• All WiFi standards: 2.4GHz and 5GHz applications: Wi-Fi 6, WiFi 6E, 802.11AX, 802.11AC, 802.11N, 802.11G, 802.11B, 802.11A
• Cellular Wireless LTE / 4G, GSM / 3G WiMax: Data and voice applications
• IoT wireless, automation & M2M: Bluetooth, ZigBee, RFID, LoRa, LTE-m, NB-IoT.
• SMA features and critical information

SMA female connector includes a bulkhead nut and washer for mounting and weatherproofing the connector/port:

• This can be used to mount the connector (and thus the cable) on the wall of a network enclosure (to weatherproof the cable connection) or on a case, panel, or Printed Circuit Board (PCB).
•  Weatherproofing: Seal the hole where the female connector is mounted by placing an O-ring between the enclosure's wall and the bulkhead nut and washer on the female connector.
• Our cables with SMA and RP-SMA female connectors have bulkhead mount hardware.
• Our standard SMA-female connector (threaded part) is 3/8 inches long. We have a more extended option: 14.5mm, which is available. The longer 14.5mm option has an O-ring embedded in the flange to waterproof the port where the cable enters a network enclosure.

SMA male and female diameter :

• SMA female outside diameter is 5/16" (7.9375mm): Accommodates a hex nut (bulkhead nut) with 5/16" nominal outer diameter
• The inside diameter of the SMA male is 5/16" (7.9375mm) (the inside diameter where the threads are).

Other SMA Characteristics and Key Points

• The SMA female connector is also called a "jack," and the SMA male is also called a "plug."
• We offer an SMA wrench to assist in installing antennas, cables, and adapters with SMA or RP-SMA connector(s).
• SMA-female connector fits items that have an SMA-male connector.
• SMA is a round screw-type connector with medium-sized, threaded coupling connectors rated for frequencies from the lowest (DC) up to 18GHz.
• SMA connectors are incompatible with the standard, commercially available Type F coaxial connector. Although they look similar, Type F connectors are slightly different in size and will not pair with RP-SMA connectors without an adapter.

Composition of SMA Connectors:

• 96%  brass-copper alloy
• Less than 4% lead content ( ROHS Compliant )
• 0.1% Chromium VI compound
• 0.01% (by weight) Cadmium/cadmium compounds
• 0.1% Mercury
• 0.1% PBBs
• 0.1% PBDE

Insertion loss: 0.26 dB maximum
