D38999/20FC98SN is Series III flange‑mount receptacle complying with MIL‑DTL‑38999 standard. FC stands for nickel‑plated aluminum shell, 98SN defines insert layout and socket contact configuration.
Built with anti‑tilt insertion design, this circular connector delivers reliable EMI/RFI shielding and high‑density contact arrangement. It carries solid three‑proof performance against moisture, mould and salt‑fog, and holds up well under high‑strength vibration and sharp temperature shifts. Operating temperature covers ‑65℃ to +175℃, matching most aerospace and defence equipment requirements.
This receptacle works with standard M39029 crimp‑style socket contacts. Operators need dedicated insertion‑extraction tools to install or remove contacts on site. The sealed structure on plug interface and tail section stops dust and moisture from getting inside the housing.
Every D38999/20FC98SN goes through our full in‑house manufacturing workflow, from CNC shell machining, insulator moulding, component assembly to batch QC checks. Our QC team inspect shell surface, sealing condition, dimension tolerance and electrical performance before packing. We filter out non‑conforming parts to keep batch consistency.
We supply ready‑stock units as well as custom modification service for special project needs. Matching contacts, sealing accessories and assembly tools can be provided together. Many overseas clients order samples first to run lab validation before placing bulk orders. Global shipping options are supported, get in touch for datasheet, lead‑time and quotation.
Mass production
D38999/20FC98SN belongs to Series III flange‑mount receptacle under MIL‑DTL‑38999 circular connector standard. The FC code stands for electroless nickel‑plated aluminum shell; 98SN defines its insert layout and socket‑type contact arrangement.
This hardware adopts anti‑tilt (scoop‑proof) insert design, delivering stable EMI/RFI shielding and high‑density contact configuration. It carries solid three‑proof performance against moisture, mould and salt‑fog, and can cope with strong vibration plus wide temperature fluctuation. Its working temperature ranges from ‑65℃ up to +200℃, making it fit for aerospace, defense and industrial automation equipment.
This flange receptacle works with standard M39029 crimp‑style socket contacts. Operators need dedicated insertion‑extraction tools to mount or take out contacts on site. Both mating face and tail section adopt sealed construction, blocking dust and humid moisture from entering internal housing space.
Every D38999/20FC98SN goes through our full in‑house manufacturing workflow, covering CNC shell machining, insulator moulding, component assembly and batch‑wise QC inspection. Our QC staff will check shell surface finish, sealing status, dimension tolerance and electrical performance before packing. Non‑conforming units get filtered out to maintain consistent batch quality.
We supply ready‑stock units as well as custom modification service for special project requirements. Matching contacts, sealing gaskets and assembly tools can be supplied together. Many overseas clients will place sample orders first for lab evaluation before moving to mass purchase. Global shipping options are supported. You can reach out to us for datasheet, lead‑time and formal quotation.
