What is an SMA Connector?
What is an SMA Connector? Rfrk
SMA connector are coaxial RF connectors developed in 1960s and SMA is the abbreviation of SubMiniature version A. SMA connector has a 50ohm impedance, 1/4-36 thread type coupling mechanism and this RF connector offers excellent electrical performance from 0 to 18GHz.

SMA connectors are available in various quality classes for different applications with different material options.  Various SMA connectors are widely used in Vehicle Tracking System, Wireless LAN, WiMax, Telecommunication, Aero and precise testing instrumentation.

Mechanical Feature:

1/4″-36 thread coupling
SMA Male is equipped with 8mm hex nut to allow torque by wretch. SMA connector’s hex nut normally is made by brass but stainless steel also is available for better corrosion resistance.
A silicon rubber O-ring is embedded between main body and coupling nut for dust resistance.
SMA Female has 4.32mm length thread for coupling purpose, and 6.24mm diameter of thread area.
How to judge SMA connectors’ feature from outline

SMA Male (Plug)
What is an SMA Connector? Nhe3

SMA Connector Male (Plug)
SMA Male is equipped with 8mm hex nut to allow torque by wretch.  SMA coupling nut has inner thread and male pin.

SMA Female (Jack)
What is an SMA Connector? 4zy1

SMA Connector Female (Jack)
SMA Female has 4.32mm length outer thread for coupling purpose, and 6.24mm diameter of thread area.

Right Angle type SMA Male and Female Connector
What is an SMA Connector? 5o1x

SMA Right Angle Connector
The cable entry way is at 90 degree against coupling way.

Straight type SMA Male and Female Connector
What is an SMA Connector? Mvyr

SMA Straight Connector
The cable entry way is at 180 degrees to coupling way.

Bulkhead type SMA Female
What is an SMA Connector? 43l7

SMA Bulkhead Rear and Front Mount type
When thread length is much longer than around 4.5mm and it is equipped with washer and nut, we can definite it as bulkhead mount type. Bulkhead means the connector can be mounted on wall or panel with washer and nut.

Rear mount type bulkhead
SMA connector rear mount bulkhead type goes through the panel mounting hole toward the external of device from the internal, and mount it with washer and nut from outside.

Front mount type bulkhead
SMA connector front mount bulkhead type goes through the panel hole toward the internal of device from the external, and mount it with washer and nut from inside.

SMA female Bulkhead with O-ring
What is an SMA Connector? Xofl

SMA female Bulkhead with O-ring
A sealing O-ring is embedded inside the hex flange. After mounting onto panel sheet with washer and nut, the O-ring can resist dust and moisture.

SMA male / female 2 holes Panel mount
What is an SMA Connector? 8fgc

SMA 2 holes flange connector with extended PTFE
2 thru holes on connector flange. The flange is exposed outside. Two screws are inserted into and have nuts to fix from the internal of enclosure.

SMA male / female 4 holes Panel mount
What is an SMA Connector? Id9w

SMA 4 holes flange mount connector
4 thru holes on connector flange. The flange is exposed outside. Four screws are inserted into and have nuts to fix from the internal of enclosure.

SMA male / female PCB type
What is an SMA Connector? 1kxg

SMA Male (Plug) and Female (Jack) PCB type Connector
PCB type SMA connector normally has 2.9mm or 3.9mm leg lengths. Four legs and one conductor will go through PCB vertically, and be soldered in rear side of PCB.

SMA male / female edge mount (end launch)
What is an SMA Connector? Jwcd

SMA Male (Plug) and Female (Jack) Edge mount Connector
SMA edge mount connector will be mounted with the PCB from board’s edge side

SMA male / female SMT type

SMT type SMA connector has very short legs from 0.5mm~1.6mm. Legs and conductor will be mounted on PCB’s surface.

PS. We distinguish SMT and PCB type SMA connectors according to the leg length normally.
