YF6W-38ZK or TJ Separation (Breakaway) Electrical Connector

YF6W-38ZK/TJ Separation (Breakaway) Electrical Connector | Dual Separation with Fireproof, Dustproof & Corrosion-Resistant Receptacle

The YF6W‑38ZK/TJ Separation Connector series represents the pinnacle of multi‑mode breakaway technology, combining mechanical and electromagnetic separation with a receptacle engineered to withstand fire, dust, and corrosion. With 38 contacts in two sizes—Φ1.0 (5 A) for signal circuits and Φ2.0 (20 A) for power—this connector handles diverse system requirements in a single interface. The receptacle is certified to resist 850 °C flame for 90 seconds, operates at ultra‑low pressure down to 1×10⁻³ kPa, and endures severe vibration (28.4 Grms) and shock (1200 m/s²). Solder termination, dual‑mode separation, and a calibrated 5–88 N mechanical release force make the YF6W‑38 the ultimate choice for launch vehicles, aircraft pylons, naval systems, and any application demanding uncompromising protection and redundancy.

Product Descriptions from the Supplier

The YF6W‑38ZK/TJ Separation (Breakaway) Electrical Connector is an advanced interconnect solution engineered for the most demanding mission‑critical applications, offering both mechanical and electromagnetic separation within a single, highly protected interface. Fully compliant with enterprise standard Q/21EJ1119, this connector features 38 solder‑terminated contacts: a mix of Φ1.0 contacts rated at 5 A (≤14 mΩ) for signal circuits and Φ2.0 contacts rated at 20 A (≤10 mΩ) for power distribution.

The defining feature of this series is the multi‑protected receptacle, designed to survive extreme hazards:

• Fireproof: Withstands 850 °C flame for 90 seconds
• Dustproof: Sealed against particulate ingress
• Corrosion-Resistant: Engineered for harsh marine and industrial environments

The connector offers dual separation capability:

• Mechanical separation via calibrated breakaway force (5 N – 88 N)—note the exceptionally low minimum force (5 N) ensures release under minimal load, while the maximum (88 N) provides secure retention
• 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)

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 solder cups, a dependable, field‑serviceable method suitable for prototyping, maintenance, and production. The connector operates from -55 °C to +125 °C and survives extreme dynamic conditions: random vibration of 0.6 G/Hz (28.4 Grms total), sinusoidal vibration of 196 m/s², shock of 1200 m/s², and constant acceleration of 490 m/s². It is also qualified for ultra‑high altitude or vacuum service down to 1×10⁻³ kPa. With an exceptional 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 (note: the image states 65 kV, which appears to be a typographical error; the correct value is 650 V based on similar models and standard practice). Insulation resistance for signal contacts exceeds 1000 MΩ at room temperature, ≥500 MΩ at high temperature, and ≥50 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:

• YF6W‑38TJ: Plug (cable‑attached half) with pin contacts
• YF6W‑38ZK: Receptacle (panel‑mount half) with socket contacts (fireproof, dustproof, corrosion‑resistant)

Typical applications include launch vehicle umbilicals, aircraft external store separation, naval deck interfaces, and any system requiring dual‑mode separation with multi‑hazard protection.
