The ST12 series is the smallest metal shell connector among our other connectors, ST12 and SF12 has the same insert, same contacts and same electric spec, just different shell and different coupling, ST12 is cheaper than SF12.
This miniature connector is a IP67 connector, thread coupling, The body is made of zinc alloy with chrome plating, it can be front mount and rear mount.
The connectors can be used for both cable to cable (in-line) and cable to panel-mount connections. Each side can be male or female contact, (Plug or socket versions).
