VG 95328 Connectors:
Complete Guide to the German Military Bayonet Circular Connector Standard

When a European defense platform specifies a "VG" connector, it is not asking for a MIL-spec part with a different label. It is specifying a connector built to Germany's national defense equipment standards — a family of interconnects that is physically interchangeable with MIL-DTL-26482 yet carries its own qualification trail, part-number grammar, and procurement path.

VG 95328 is the workhorse of that family: a compact, high-density, bayonet-coupled circular connector that has been the default signal interconnect for German and NATO-aligned armored vehicles, naval systems, aerospace platforms, and railway rolling stock for decades. This guide covers what the standard actually specifies, how to decode a VG 95328 part number, how it differs from MIL-DTL-26482, and where to source qualified equivalents.

1. What Is VG 95328?

VG stands for Verteidigungsgerät ("defense equipment") — the German equivalent of the U.S. MIL-STD/MIL-SPEC system, administered through BAAINBw (the Federal Office for Bundeswehr Equipment). VG standards are also recognized and specified by other NATO-aligned countries, including Armasuisse (Switzerland) and the Dutch Ministerie van Defensie.

VG 95328 defines a family of miniature, environmentally sealed, bayonet-lock circular connectors built on the MIL-C-26482 (now MIL-DTL-26482) Series I foundation. Qualified VG 95328 connectors share the same:

• Insert arrangements — the same contact layouts as MIL-DTL-26482
• Shell dimensions — shell sizes 8 through 24
• Contact system — size #12, #16, and #20 contacts (crimp and solder)
• Electrical ratings — identical current-carrying performance

In practice this means a VG 95328 connector intermates with MIL-DTL-26482 Series I and II connectors. A harness built with VG 95328 plugs will couple to a panel fitted with MS3112 or MS3126 receptacles — a property that makes the standard attractive to integrators who must support both U.S. and European supply chains.

2. VG 95328 vs MIL-DTL-26482: What Actually Changes

If the connectors intermate, why maintain a separate standard at all? The differences are in the procurement and qualification layer, not the mated interface:

The practical takeaway for a buyer: you can substitute VG 95328 for MIL-DTL-26482 without redesigning the mating half, which is why European programs often dual-source the same interconnect from both VG-qualified and QPL-qualified manufacturers.

3. Decoding a VG 95328 Part Number

VG 95328 part numbers follow a compact grammar. Take VG95328M24-61PN:

Common Airoadcon VG 95328 part numbers map cleanly to their MIL-DTL-26482 equivalents:

4. Shell Styles and Contact System

VG 95328 is specified across the full set of standard shell styles, matching the MIL-DTL-26482 lineup:

• Straight plug — cable-mount free connector with accessory threads
• Front panel mount square-flange receptacle — with accessory threads
• Rear box mount square-flange receptacle — no accessory threads
• Through-bulkhead receptacle — for pressure-vessel and enclosure wall penetrations
• Jam-nut receptacle — rear-panel mounting in tight spaces

The contact system uses removable crimp contacts (the default for production harnesses) alongside solder-cup variants for low-volume and prototype work. Contact current ratings follow the 26482 family:

• #20 — 7.5 A per contact (high-density signal)
• #16 — 13 A per contact
• #12 — 23 A per contact (power)

Across the nine shell sizes (8–24), insert arrangements range from 2 contacts up to 61 contacts in a single shell-24 connector — the maximum density available in this form factor. VG 95328 connectors are typically rated for -65°C to +200°C, 500+ mating cycles, and IP67 sealing when mated.

5. Bayonet Coupling, Keying, and Sealing

The defining ergonomic feature of VG 95328 is its 3-point bayonet coupling. A one-third turn of the coupling ring drives three bayonet studs into three ramped slots, producing:

• Fast, tool-free mating — ideal for blind or hard-to-reach mounting positions
• Audible and visual coupling indicators — the operator can confirm a full mate without seeing the connector
• High vibration resistance — the bayonet lock resists back-off under shock and vibration

Five keyway positions (N, A, B, C, D) prevent cross-mating when multiple identical connectors are mounted side-by-side on the same panel — a common situation in densely wired vehicle bulkheads. Environmental sealing comes from resilient interfacial seals and wire-sealing grommets, the same neoprene/rubber insert system used in 26482.

6. Materials and Plating

Shells are aluminum alloy. Plating follows the same options buyers already know from MIL-DTL-26482, with the VG qualification adding its own designations:

For new European programs, black zinc-nickel is the most common specification — it satisfies REACH/RoHS while maintaining the conductive, corrosion-resistant surface the bayonet ground path depends on.

7. Where VG 95328 Is Used

The standard dominates European defense ground vehicles and extends into adjacent markets where a rugged, fast-mating signal connector is required:

• Armored vehicles & main battle tanks — hull and turret harnesses, sensor and communication lines
• Naval systems — deck equipment, below-deck electronics, and shipboard control wiring
• Military aerospace — avionics bays and ground-support equipment
• Railway rolling stock — braking, signaling, and auxiliary power circuits
• Heavy construction & agricultural equipment — engine and chassis harnesses where dirt and vibration are constant

8. Manufacturer Cross-Reference

Because VG 95328 shares geometry with 26482, most 26482-capable manufacturers also offer a VG-qualified line. The main suppliers and their series designations:

Airoadcon's VG 95328 line is form-fit-function interchangeable with all of the above and is tested to the same performance envelope: -65°C to +200°C, 500+ mating cycles, IP67 mated sealing, olive drab Cd or black Zn-Ni plating. Every part number in the Airoadcon catalog maps directly to its MIL-DTL-26482 equivalent, so a buyer can dual-source without changing drawings.

9. VG 95328 vs VG 95234: Don't Confuse the Two

Both carry the "VG" prefix, but they are entirely different connectors:

If the program calls for a compact, high-density signal connector with quick bayonet coupling, VG 95328 is the answer. If it calls for rugged power with reverse-bayonet coupling and larger contacts, that's VG 95234. (See our VG 95234 guide for the full comparison.)
