The base code '/26FC35' specifies the connector's shell style, finish, shell size, and insert arrangement. '/26' indicates a Series III straight plug shell style. 'F' denotes an electroless nickel plating on an aluminum body, providing EMI shielding, 48-hour salt spray resistance, and a 200°C operating temperature. 'C35' (or '13-35') specifies a shell size of 13 and an insert arrangement of 35, accommodating 22 contacts. The suffix 'PN' specifies the contact type and keying position. 'P' indicates pin (male) contacts. 'N' indicates a normal keying position. The prefix D38999 identifies the MIL-DTL-38999 specification standard for circular connectors, widely used in aerospace, defense, and harsh environment applications.
