YF15-42ZK or TJ Separation (Breakaway) Electrical Connector

YF15-42ZK/TJ Separation (Breakaway) Electrical Connector | High-Low Frequency Hybrid with Crimp Termination

The YF15‑42ZK/TJ Separation Connector series delivers exceptional flexibility in a single breakaway interface, supporting four different contact sizes to accommodate everything from low‑level signals to 40 A power circuits. With 20#, 16#, 12#, and 10# contacts all available within the same connector, system designers can optimize their interface for mixed power and signal requirements without needing multiple connector types. Crimp termination ensures reliable, repeatable terminations suitable for high‑volume production, while the calibrated 50–250 N separation force covers a wide range of release requirements. Qualified to rigorous vibration and shock standards, the YF15‑42 is the ideal choice for launch vehicle umbilicals, aircraft external stores, and naval systems requiring hybrid capability in a single separation interface.

Product Descriptions from the Supplier

The YF15‑42ZK/TJ Separation (Breakaway) Electrical Connector is a versatile hybrid interconnect solution engineered for applications requiring a mix of signal and power circuits within a single separation interface. Fully compliant with enterprise standard Q/21EJ1230, this connector features crimp‑terminated contacts available in four sizes: 20# (7.5 A), 16# (13 A), 12# (20 A), and 10# (40 A). All contacts maintain a maximum contact resistance of 10 mΩ (except 10# which is ≤5 mΩ), ensuring efficient power transfer and signal integrity.

The defining feature of this series is its multi‑contact flexibility, allowing system designers to select the optimal mix of current ratings within a single connector body—eliminating the need for multiple separate connectors and simplifying cable harnesses.

All contacts are terminated via crimp technology, providing reliable, repeatable connections suitable for high‑volume production and field maintenance. The mechanical separation mechanism is calibrated to release with a force of 50–250 N, covering a wide range of applications from light‑duty signal interfaces to heavy‑duty power disconnects.

Engineered for harsh environments, the YF15‑42 operates from -55 °C to +125 °C and survives severe dynamic conditions: random vibration of 0.3 G²/Hz and shock of 735 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 (50 Hz, 1 minute). Insulation resistance exceeds 3000 MΩ at room temperature, remains ≥500 MΩ at high temperature, and maintains ≥20 MΩ after humidity testing, ensuring long‑term reliability.

Available in two configurations:

• YF15‑42TJ: Plug (cable‑attached half) with pin contacts
• YF15‑42ZK: Receptacle (panel‑mount half) with socket contacts

Typical applications include launch vehicle umbilicals, aircraft external store separation, naval power/signal interfaces, and any system requiring mixed contact ratings in a single breakaway package.
