Russian-standard military connectors — primarily the ZH23, OHS, and 2PX series — are the backbone of defense and industrial equipment across Eastern Europe, the Middle East, South Asia, and Africa. Millions of legacy platforms (tanks, APCs, aircraft, naval vessels, radar systems) use these connectors, and the demand for reliable aftermarket sourcing has never been higher.
With disrupted supply chains from traditional Russian manufacturers, NATO-aligned and neutral countries are increasingly seeking qualified alternative suppliers — and that's where Airoadcon comes in.
| Series | Standard | Type | Key Features |
|---|---|---|---|
| ZH23 | International Military | Bayonet circular | Quick-connect, 7-30mm shell sizes, -60°C to +155°C, IP67 |
| OHS | International Military | Bayonet circular | Compact, high-density, nuclear-qualified variants available |
| 2PX | International Military | Threaded circular | Anti-vibration, high-current (up to 150A), subsea capable |
| P.ZP.PR | Industrial | Push-pull rectangular | Quick-disconnect, modular, rack-and-panel mounting |
| ZH28 | Military | Screw circular | High-reliability, hermetic sealed variants, vacuum-rated |
| PC | Military | Threaded circular | RF/coax contacts, EMI-shielded, filter options |
| MP1 | Military | Bayonet circular | Miniature, lightweight, aerospace-qualified |
ZH23 is the most widely deployed Russian-standard circular connector. It uses a bayonet coupling mechanism similar to MIL-C-26482 but with Russian contact arrangements. Shell sizes range from 7 (7 contacts) to 30 (61+ contacts), making it suitable for everything from sensor connections to power distribution.
| Part Number | Type | Contacts | Shell Size | Plating |
|---|---|---|---|---|
| ZH23-7/1-P-1-B | Straight Plug | 7× #1.5mm Pin | 7 | Cadmium |
| ZH23-10/4-R-B | Wall Mount Rec. | 10× #1.5mm Socket | 10 | Cadmium |
| ZH23-14/7-R-1-V | Jam Nut Rec. | 14× #1.5mm Socket | 14 | Nickel |
| ZH23-18/10-P-B | Straight Plug | 10× #2.5mm Pin | 18 | Cadmium |
| ZH23-24/21-R-V | Wall Mount Rec. | 21× #1.5mm Socket | 24 | Nickel |
| ZH23-30/35-P-1-B | Straight Plug | 35× #1.5mm Pin | 30 | Cadmium |

The OHS series is designed for applications requiring higher contact density in smaller shells. It's widely used in Russian military communication systems, radar signal distribution, and nuclear power plant instrumentation. OHS connectors maintain performance under radiation exposure and seismic conditions.
| Part Number | Configuration | Application |
|---|---|---|
| OHS-BC14/10P21B | 14 shell, 10 pins | Military radio/communication |
| OHS-BC18/16S21B | 18 shell, 16 sockets | Radar signal distribution |
| OHS-BC24/24P21V | 24 shell, 24 pins | Nuclear instrumentation |
| OHS-BC10/7S21B | 10 shell, 7 sockets | Compact sensor connections |
The 2PX threaded circular series is engineered for high-current and high-reliability applications. With current ratings up to 150A per contact, 2PX is the go-to choice for naval power distribution, subsea equipment, and heavy industrial machinery. The threaded coupling provides superior vibration resistance compared to bayonet-lock alternatives.
| Part Number | Contacts | Current Rating | Typical Use |
|---|---|---|---|
| 2PXT-10B4P-1A-V | 4× Pin | 25A each | Actuator/servo power |
| 2PXT-14B7S-V | 7× Socket | 40A each | Motor control |
| 2PXT-18B3P-1A-B | 3× Pin | 100A each | Battery/power distribution |
| 2PXT-24B2P-B | 2× Pin | 150A each | Subsea power, winches |
