YF6-51ZK or TJ Separation (Breakaway) Electrical Connector

YF6-51ZK/TJ Separation (Breakaway) Electrical Connector | Dual Separation with 51 High-Density Contacts

The YF6‑51ZK/TJ Separation Connector series delivers the highest contact density in our dual‑mode separation family, featuring 51 gold‑plated Φ1.0 contacts rated at 5 A each. Engineered to Q/21EJ275 standards, this connector combines mechanical and electromagnetic separation with a receptacle designed to withstand fire, dust, and impact—ideal for the most demanding aerospace and naval applications. Solder termination ensures reliable field connections, while the calibrated 28–88 N mechanical separation force and fast electromagnetic release (≤0.1 s) provide redundant safety for mission‑critical events. When your system requires maximum circuit density with dual‑mode redundancy and environmental protection, the YF6‑51 series delivers.

Product Descriptions from the Supplier

The YF6‑51ZK/TJ Separation (Breakaway) Electrical Connector is a high‑density interconnect solution engineered for applications requiring maximum circuit count within a single separation interface, combined with dual‑mode redundancy and environmental protection. Fully compliant with enterprise standard Q/21EJ275, this connector features 51 solder‑terminated Φ1.0 contacts rated at 5 A each with a maximum contact resistance of 10 mΩ, providing ample capacity for complex signal and control systems.

The defining features of this series include:

• Protected Receptacle: Engineered to be fireproof, dustproof, and impact‑resistant—ensuring reliable operation in harsh operational environments
• Dual Separation Capability:
  • Mechanical separation via calibrated breakaway force (28–88 N)
  • Electromagnetic separation using an integrated solenoid, activated by a 23–31 V DC pulse (≥200 ms) with separation occurring in ≤0.1 s (maximum energizing time ≤5 s)

All contacts are terminated via solder cups, a dependable, field‑serviceable method suitable for prototyping, maintenance, and production. The connector operates from -55 °C to +125 °C and survives severe dynamic conditions: random vibration of 0.3 G²/Hz (20 Grms), sinusoidal vibration of 150 m/s², shock of 735 m/s², and constant acceleration of 30 g. With a mechanical life of 500 mating cycles, these connectors are suitable for ground testing and operational reuse.

Dielectric withstanding voltage is 1000 V AC rms at sea level, derated to 500 V under humidity and 150 V at low pressure (1 kPa). 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:

YF6‑51TJ: Plug (cable‑attached half) with pin contacts

YF6‑51ZK: Receptacle (panel‑mount half) with socket contacts (fireproof/dustproof/impact‑resistant)

Typical applications include launch vehicle umbilicals, aircraft external store interfaces, naval combat systems, and any application requiring high circuit density with dual‑mode redundant separation and environmental protection.
