The MS3102E28-21S is a MIL-DTL-5015 box mount receptacle in shell size 28 with insert arrangement 28-21, carrying 37 #16 contacts. MIL-DTL-5015 (MS5015) is the original thread-coupled circular connector standard for heavy industrial and aerospace duty: a scoop-proof, single-keyway shell with a threaded coupling nut that resists vibration and back-driving far better than a bayonet.
Service class E is environment resisting, grommet and cable clamp. Each #16 contact is rated 13 A per contact; the insert is rated 700 VDC / 500 VAC rms and the assembly operates from -55 °C to +125 °C with 5,000 MΩ minimum insulation resistance. Contacts are solder cup, so the connector is suitable for field repair without crimp tooling.
