Product Overview
Engineered for high-voltage feedthrough connections, the Amphenol 10400 is a straight bulkhead-mount MHV (Miniature High Voltage) coaxial receptacle. Featuring a nickel-plated brass body and a pressurized glass-to-metal hermetic seal, this connector provides secure barrier isolation up to 5000 VDC. The rear interface terminates in a flat solder lug with an eyelet for direct wiring, while the front bayonet interface accepts standard MHV plugs.

Frequently Asked Questions
What mounting hardware comes with each connector?
Each unit includes one nickel-plated hex nut, one internal-tooth lock washer, and one red silicone O-ring sealing gasket.
How does this connector maintain a seal through a bulkhead?
The connector features a pressurized glass-to-metal seal fused directly between the center conductor and the outer shell, while the included silicone gasket seals against the panel face when the hex nut is tightened.
Can this MHV receptacle be used with standard 50-ohm BNC cables?
No. While MHV connectors look similar to standard BNC connectors and share a two-stud bayonet locking style, the center contact and dielectric insulator extend further forward to support 5000 VDC ratings. They require dedicated MHV plugs and will not mate with standard BNC cables.
High-voltage feedthroughs leave no room for leaks, and Amphenol's glass-to-metal seals were built to hold the line. Bolt it through the chassis, land your lead on the eyelet, and let your rig run.
