D38999/26WC98SN — MIL-DTL-38999 Series III Straight Plug (Shell Size 13, 10 Socket Contacts)
D38999/26WC98SN is a genuine MIL-DTL-38999 Series III circular connector — a free-hanging straight plug with EMI grounding fingers, built for the harshest military, aerospace, and avionics wiring environments. It ships with 10 gold-plated crimp socket contacts in shell size 13, olive drab cadmium finish, and mates via rapid tri-start quick-coupling thread.
Like every D38999 Series III connector, it withstands extreme shock, vibration, moisture, and corrosion, and is qualified to MIL-DTL-38999.

Mating Information
D38999/26WC98SN is a free-hanging plug and is designed to mate with a fixed-panel D38999/20 (wall mount) or D38999/24 (jam nut) receptacle of the same shell size (13/”C”) and insert arrangement (98), fitted with pin contacts. Confirm the exact mating receptacle part number and finish class against your harness drawing or the Amphenol datasheet before ordering.
FAQ
1. What does D38999/26WC98SN mean?
It decodes to a MIL-DTL-38999 Series III straight plug (/26), olive drab cadmium finish (W), shell size 13 (C), insert arrangement 98 (10 positions), socket contacts (S), normal keying (N).
2. How many contacts does D38999/26WC98SN have?
10 socket contacts, per insert arrangement 98.
3. What is the shell size of D38999/26WC98SN?
