YF6A-45ZK or TJ Separation (Breakaway) Electrical Connector

YF6A-45ZK/TJ Separation (Breakaway) Electrical Connector | Dual Separation with Triple Protection & High-Density Hybrid Interface​​​​​​​​​​​​​​

The YF6A‑45ZK/TJ Separation Connector series represents the ultimate in high‑density, dual‑mode separation technology, combining 45 mixed‑signal contacts with triple‑protected receptacle features in a single, rugged interface. Engineered to the exacting requirements of Q/21EJ1119, this connector supports both mechanical and electromagnetic separation while providing fireproof (850°C/90s), dustproof, and corrosion‑resistant protection for the receptacle. With an ultra‑low pressure rating of 1×10⁻⁵ kPa, it is qualified for the most demanding space and high‑altitude applications. The hybrid termination approach—crimp for high‑frequency contacts, solder for low‑frequency contacts—ensures optimal reliability for each signal type. With an extended mechanical life of 1000 cycles and proven resistance to severe vibration (28.4 Grms) and shock (1200 m/s²), the YF6A‑45 is the premier choice for launch vehicles, spacecraft, naval combat systems, and any application requiring high‑density hybrid signal capability with redundant release and extreme environmental protection.

Product Descriptions from the Supplier

The YF6A‑45ZK/TJ Separation (Breakaway) Electrical Connector is an advanced interconnect solution engineered for the most demanding aerospace and defense applications, offering dual‑mode separation, triple environmental protection, and high‑density hybrid signal capability within a single interface. Fully compliant with enterprise standard Q/21EJ1119, this connector features 45 solder‑terminated (low‑frequency) Φ1.0 contacts rated at 5 A each with a maximum contact resistance of 10 mΩ, plus integrated high‑frequency contacts for RF, video, or high‑speed data transmission.

The defining features of this series include:

• Triple-Protected Receptacle: Fireproof (850°C for 90 s with insulation ≥20 MΩ), dustproof, and corrosion‑resistant—designed for the harshest operational environments
• Dual Separation Capability:
  • Mechanical separation via calibrated breakaway force (40–88 N)
  • Electromagnetic separation using an integrated solenoid, activated by a 24–31 V DC pulse (≥200 ms) with separation occurring in ≤0.1 s (maximum energizing time ≤5 s)
• Ultra-Low Pressure Qualification: Certified to 1×10⁻⁵ kPa for space, high‑altitude, and vacuum applications
• Hybrid High-Low Frequency Configuration: Supports mixed signal types including RF/data alongside conventional circuits
• Hybrid Termination: Crimp termination for high‑frequency contacts (controlled impedance); solder termination for low‑frequency contacts (field serviceability)

This dual‑mode redundancy ensures positive release whether commanded electronically or via mechanical force, critical for space launch, weapon systems, and emergency jettison scenarios.

All contacts are terminated via the appropriate method for each signal type. The connector operates from -55 °C to +125 °C and survives extreme dynamic conditions: random vibration of 0.6 G/Hz (28.4 Grms), sinusoidal vibration of 196 m/s², shock of 1200 m/s², and constant acceleration of 490 m/s². With an extended mechanical life of 1000 mating cycles, these connectors are built for repeated ground testing and operational reuse.

Dielectric withstanding voltage is 1000 V AC rms at sea level, derated to 500 V under temperature extremes and humidity, and 200 V at low pressure. Control wires for electromagnetic components are rated at 650 V AC rms to shell. Insulation resistance for signal contacts exceeds 1000 MΩ at room temperature, ≥500 MΩ at high temperature, and ≥20 MΩ after humidity testing. Electromagnetic components maintain ≥100 MΩ at room temperature, ≥50 MΩ at high temperature, and ≥10 MΩ after humidity.

Available in two configurations:

• YF6A‑45TJ: Plug (cable‑attached half) with pin contacts
• YF6A‑45ZK: Receptacle (panel‑mount half) with socket contacts (fireproof/dustproof/corrosion‑resistant)

Typical applications include launch vehicle umbilicals, spacecraft separation systems, aircraft external store interfaces, naval combat systems, and any application requiring high‑density hybrid signal capability with redundant separation and extreme environmental protection.
