YF6-56ZKY or TJY Separation (Breakaway) Electrical Connector

YF6-56ZKY/TJY Separation (Breakaway) Electrical Connector | Rainproof Mated Interface with High-Current Contacts

The YF6‑56ZKY/TJY Separation Connector series delivers high‑density, multi‑current capability in a rainproof, breakaway package. Featuring 56 crimp‑terminated contacts supporting currents from 5 A to 22 A (depending on contact size), this connector family offers exceptional design flexibility for complex aerospace and naval separation interfaces. The mated interface is sealed against rain ingress, ensuring reliable operation in exposed environments. With altitude capability to 15,250 m, proven vibration and shock resistance, and a calibrated 28–50 N separation force, the YF6‑56 series delivers reliable performance in launch vehicle umbilicals, aircraft external stores, and naval deck connections where both high circuit density and environmental protection are required.

Product Descriptions from the Supplier

The YF6‑56ZKY/TJY Separation (Breakaway) Electrical Connector is a versatile, high‑capacity interconnect solution engineered for applications requiring multiple contact current ratings within a single separation interface, combined with rainproof protection when mated. Fully compliant with enterprise standard Q/21EJ1099, this connector features 56 crimp‑terminated contacts available in various sizes to accommodate currents from 5 A up to 22 A, making it ideal for mixed power and signal circuits within a single separation interface.

A standout feature is the rainproof sealing when mated, ensuring that the connector interface remains protected against water ingress during operation—critical for exposed installations such as launch vehicle umbilical panels, aircraft external stations, or naval deck equipment.

The contact complement includes:

• 16# contacts: Up to 22 A with contact resistance ≤2.5 mΩ
• 20# contacts: Up to 20 A with contact resistance ≤5 mΩ
• 22# contacts: Up to 5 A with contact resistance ≤12.5 mΩ

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 YF6‑56 operates from -55 °C to +125 °C and withstands altitude conditions down to 11.6 kPa (15,250 m). Dynamic capabilities include vibration of 0.4 G²/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 humidity and 150 V at low pressure. Insulation resistance exceeds 1000 MΩ at room temperature and remains ≥20 MΩ after humidity testing, ensuring long‑term reliability.

Available in two configurations:

• YF6‑56TJIY: Plug (cable‑attached half) with pin contacts
• YF6‑56ZKY: Receptacle (panel‑mount half) with socket contacts (rainproof when mated)

Typical applications include launch vehicle umbilicals, aircraft external store separation, naval deck interfaces, and any system requiring high circuit density with rainproof protection.
