The four-electric coaxial connector is a mateable flange-and-plug pair that carries four electrical cores plus one coaxial RF channel through a square-flange penetration. One part handles a camera or modem feed — power, ground, control — and the RF link, in a single sealed unit.
Product Highlights
- 4 electrical + 1 coaxial per penetration: power and RF share one sealed pass-through instead of two.
- Square 4-hole flange: bolt-through mounting spreads the seal load evenly and suits flat housing walls.
- Central coaxial contact: the RF pin sits on the axis, surrounded by the four electrical contacts in one insert.
- Threaded quick-mate plug: the line-side plug couples with a knurled ring — hand-tight is enough to seat the seal.

Structure & Sealing
The receptacle bolts to the housing wall through its square flange; a face O-ring between flange and wall carries the seal. The contact insert holds the central coaxial contact and four surrounding electrical contacts, all potted at the rear. The plug slides in axially and locks with a knurled coupling ring.

Packaging & Delivery
Each connector is shipped in an ESD-safe bag with a protective cap on the mating face, packed in a foam-lined carton. Lead time depends on configuration and quantity — contact us for a current schedule. DHL / FedEx / air / sea freight supported.
FAQ
Can this replace two separate connectors on my housing?
In most layouts yes — one penetration carrying 4E + 1 coax replaces a power connector and an RF feed-through. Send us the interface drawing and we will check the fit.
What is the RF performance?
It depends on the coaxial contact and cable selected — share your frequency band for the datasheet.
Is the flange hole pattern fixed?
The standard pattern is shown in the drawing; custom patterns are supported.
Do you offer samples?
Yes, sample orders before volume are welcome.
