Industrial MS27656T13F35P Circular MIL Spec Connector

MS27656T13F35P is a circular MIL‑SPEC connector from the MS27656 family, shell size 13, delivering 22 contact positions in a rear‑mount receptacle configuration with bayonet coupling for secure, vibration‑resistant mating. The component is built with an aluminum alloy body finished in electroless nickel and copper alloy pins that are gold plated, offering reliable conductivity and durability in harsh environments; supplier catalogs describe the series as environmentally sealed. It carries NSN 5935‑01‑017‑7289 and is marketed by Amphenol Aerospace (Souriau/Sunbank by Eaton lineage) with variants such as MS27656T13F35P‑LC available for alternate configurations. Typical applications include avionics harnesses in both helicopter and fixed‑wing aircraft, as well as rugged military ground equipment, where a compact 22‑position circular MIL‑SPEC interface is required to carry signaling and limited power with secure, weather‑resistant performance. As with any MS27656 part, verify mating inserts and connector mating sizes to match your harness, but this shell size 13/22‑pin arrangement is a common choice for space‑constrained, high‑reliability aerospace and defense applications.
