Product Descriptions from the Supplier

The YF8‑22ZJ/TK Separation (Breakaway) Electrical Connector is a state‑of‑the‑art interconnect solution engineered for applications requiring both conventional signal circuits and high‑speed differential data transmission within a single, miniaturized separation interface. Fully compliant with enterprise standard Q/21EJ1292, this connector features 20 size‑22# contacts rated at 5 A each for power and discrete signals, plus two 8# differential contacts optimized for high‑speed data protocols such as LVDS, Ethernet, or video signals. This hybrid configuration eliminates the need for separate data connectors, saving critical space and weight in tight installations.

All contacts are terminated via crimp technology, ensuring reliable, repeatable connections suitable for high‑volume production and field maintenance. The mechanical separation mechanism is calibrated to release with a force of 40–60 N, providing a secure hold during operation while ensuring positive separation when commanded.

Engineered for harsh environments, the YF8‑22 operates from -55 °C to +125 °C and survives severe dynamic conditions: random vibration of 0.3 g²/Hz, shock of 40 g, and constant acceleration of 490 m/s². With an exceptional mechanical life of 1500 mating cycles, these connectors are built for repeated ground testing and operational reuse.

The dielectric withstanding voltage is 1300 V AC rms at sea level, derated to 300 V under damp heat and low pressure (4.4 kPa) conditions. Insulation resistance exceeds 5000 MΩ at room temperature, remains ≥100 MΩ at temperature extremes, and stays ≥20 MΩ after humidity and mechanical testing, ensuring long‑term reliability.

Available in two configurations:

• YF8‑22TK: Plug with socket contacts (accepts pins)
• YF8‑22ZJ: Receptacle with pin contacts

Typical applications include launch vehicle umbilicals, avionics separation interfaces, UAV tether release, and any system requiring a mix of power, signal, and high‑speed differential pairs in a breakaway package.
