YF6-42ZK or TJ Separation (Breakaway) Electrical Connector

YF6-42ZK/TJ Separation (Breakaway) Electrical Connector | Large-Angle Separation up to 50°

The YF6‑42ZK/TJ Separation Connector series solves one of the most challenging problems in breakaway interface design: reliable separation when the pull direction is not perfectly aligned. Engineered to guarantee separation at angles up to 50° from the connector axis, this innovative design ensures positive release even in confined installations where cable routing cannot be perfectly straight. With 4 high‑reliability contacts rated at 5 A (≤5 mΩ), solder termination, and a robust mechanical life of 500 cycles, the YF6‑42 delivers dependable performance in launch vehicle umbilicals, aircraft emergency jettison systems, and naval towed arrays. The optional metal protective cover (YF6-42FJ) safeguards the receptacle when unmated. When your application demands reliable separation despite imperfect cable alignment, the YF6‑42 series is the answer.

Product Descriptions from the Supplier

The YF6‑42ZK/TJ Separation (Breakaway) Electrical Connector is a specialized interconnect solution engineered for applications where cable routing constraints may prevent perfectly axial pull during separation events. Fully compliant with enterprise standard Q/21EJ1492, this connector features 4 solder‑terminated contacts rated at 5 A each with an exceptionally low maximum contact resistance of 5 mΩ, ensuring minimal power loss and signal attenuation.

The defining feature of this series is its large-angle separation capability:

• Axial separation (0° pull): Calibrated separation force of 50–88 N
• Angled separation (up to 50°): Guaranteed separation with force ≤1000 N—critical for installations where cable exit angles cannot be perfectly controlled
• 180° backward pull: The mechanism also achieves reliable unlocking when the cable is pulled from the opposite direction

This unique multi‑angle release capability makes the YF6‑42 ideal for applications such as aircraft emergency jettison systems, launch vehicle umbilicals with complex cable routing, and naval towed arrays where the separation direction cannot be guaranteed.

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: sinusoidal vibration of 150 m/s² (10–2000 Hz), random vibration of 0.3 G²/Hz, shock of 735 m/s², and constant acceleration of 250 m/s². 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 250 V under temperature extremes and humidity, and 200 V at low pressure (1.1 kPa). Insulation resistance exceeds 1000 MΩ at room temperature, remains ≥50 MΩ at temperature extremes, and maintains ≥50 MΩ after humidity testing—an exceptionally high post‑humidity value ensuring long‑term reliability.

Available in three configurations:

• YF6‑42TJ: Plug (cable‑attached half) with pin contacts
• YF6‑42ZK: Receptacle (panel‑mount half) with socket contacts
• YF6‑42FJ: Metal protective cover for receptacle (sold separately)

Typical applications include aircraft emergency release systems, launch vehicle umbilicals, naval towed array disconnects, and any application where cable routing prevents perfectly axial separation.
