With altitude capability to 15,250 m, proven vibration and shock resistance, and a calibrated 28–50 N separation force, the YF6‑26 series delivers reliable performance in umbilical disconnects, stage separation, and equipment jettison applications. When your mission demands a versatile, environmentally protected separation interface, the YF6‑26 series is the answer.

Product Descriptions from the Supplier

The YF6‑26ZKY/TJY Separation (Breakaway) Electrical Connector is a versatile, high‑capacity interconnect solution engineered for applications requiring multiple contact sizes and enhanced environmental protection at the receptacle interface. Fully compliant with enterprise standard Q/21EJ1099, this connector features 26 crimp‑terminated contacts available in various sizes to accommodate currents from 5 A up to 23 A, making it ideal for mixed power and signal circuits within a single separation interface.

A standout feature of the YF6‑26 series is the receptacle's mounting face, which is specifically sealed to resist rain and dust ingress—critical for applications where the receptacle remains exposed after separation, such as launch vehicle umbilical panels or external aircraft stations.

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 28–50 N, providing a secure hold during operation while ensuring positive separation when commanded.

Engineered for harsh environments, the YF6‑26 operates from -55 °C to +125 °C and withstands altitude conditions down to 11.6 kPa (15,250 m). Dynamic capabilities include random vibration of 0.04 G²/Hz across 5.5–2000 Hz, shock of 40 g, and constant acceleration of 22.5 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 temperature extremes and humidity, and 150 V at low pressure. Insulation resistance exceeds 1000 MΩ at room temperature, remains ≥500 MΩ at temperature extremes, and stays ≥20 MΩ after humidity testing, ensuring long‑term reliability.

Available in two configurations:

• YF6‑26TJIY: Plug (cable‑attached half) with pin contacts
• YF6‑26ZKIY: Receptacle (panel‑mount half) with socket contacts

Typical applications include launch vehicle umbilicals, aircraft external store separation, naval deck interfaces, and any system requiring a dust/rain‑protected receptacle face.
