To build an AC series coded part number, begin with AC which designates Amphenol Industrial Series Threaded Connectors. The connector type, either solder or crimp, is entered in the second slot followed by the shell style. Next, insert the service class to designate the type of sealing, adaptor, strain relief and cable clamp. Slot five is used to designate the shell size followed by the insert arrangement and the contact type, pin or socket. Finally, designate the desired rotation in slot eight or leave it blank for normal rotation.
