Are All SMA Connectors The Same Size

No, SMA connectors are not all the same size and exist in various sizes.

An SMA connector's size can relate to a variety of things, including:

Orientation Of Connector

Straight

Right Angle

45 degree Angle

Termination Types

Cable Clamp

Cable Crimp

Cable Solder

PCB End Launch

PCB Surface Mount

PCB Through Hole

Cable Types

The thickness, flexibility, or semi-rigidity of the cables can affect the SMA connectors' diameter. For example, RG174 is a thin cable, whereas RG214 is a thick cable. Whatever clamping or crimping termination that is always larger than SMA connect to RG174 if SMA connector connect to RG214 cable.

Panel Mounting Types

2-Hole Flange

4-Hole Flange

Bulkhead for front mount

Bulkhead for rear mount

In conclusion, SMA connectors come in different sizes and their size is determined by various factors such as orientation, termination type, cable type, and panel mounting. The orientation of the connector, whether straight, right-angle, or 45-degree angle, can affect the size. The termination type, such as cable clamp, cable crimp, cable solder, PCB end launch, PCB surface mount, or PCB through hole, also affects the size. The type of cable used, whether thin or thick, also affects the size. Lastly, the panel mounting, such as 2-hole flange, 4-hole flange, bulkhead for front mount, or bulkhead for rear mount, also affects the size.
