The 901-9531-3SF is an SMA right-angle plug connector designed for termination with flexible coaxial cables. It is compatible with several cable types, including RG-174, RG-179, RG-187, RG-188, and RG-316. Assembly involves a crimp/solder center contact and a crimped outer ferrule, which requires a hex crimp size of .128 inches (3.3 mm) using the specified CTL-9 tool. This connector is ideal for RF applications where a right-angle connection is needed for cable routing or to manage space constraints.
