YF6-57 Series Separation (Breakaway) Electrical Connector

YF6-57 Series Separation (Breakaway) Electrical Connector | Dual Separation with Fireproof & Dustproof Options

The YF6‑57 Series Separation Connector family offers unparalleled flexibility for mission‑critical applications, combining mechanical and electromagnetic separation with a wide array of plug and receptacle variants to meet exact system requirements. With over ten distinct models featuring different platings (e.g., blue lacquer, electroless nickel), separation forces (28–88 N or 60–100 N), and special capabilities—such as 350 °C / 30 min operation, protective covers with moisture sealing, and offset functionality—this series can be tailored to virtually any aerospace, naval, or defense separation scenario. All variants share the same high‑reliability Φ1.0 contacts (5 A, ≤10 mΩ), dual‑mode separation (mechanical + electromagnetic), and proven resistance to vibration, shock, and humidity. Whether you need a standard interface or a custom‑configured solution, the YF6‑57 series delivers.

Product Descriptions from the Supplier

The YF6‑57 Series Separation (Breakaway) Electrical Connector is a highly versatile family of interconnect solutions engineered for applications demanding dual‑mode redundancy and extensive configuration options. Fully compliant with enterprise standard Q/21EJ275, this series features Φ1.0 contacts rated at 5 A each with a maximum contact resistance of 10 mΩ, available with either solder or crimp termination.

The series offers dual separation capability:

Mechanical separation via calibrated breakaway force (28–88 N or 60–100 N depending on model)

Electromagnetic separation using an integrated solenoid, activated by a 23–31 V DC pulse (≥200 ms) with separation occurring in ≤0.1 s (maximum energizing time ≤5 s)

A wide range of plug and receptacle variants provides exceptional design flexibility:

Note: Any plug variant can be mated with any receptacle variant, providing thousands of possible combinations.

All connectors operate from -55 °C to +125 °C and survive severe dynamic conditions: random vibration of 0.3 G²/Hz, shock of 75 m/s², and constant acceleration of 30 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 (1 kPa). Control wires for electromagnetic components are rated at 650 V AC rms to shell. Insulation resistance for signal contacts exceeds 1000 MΩ at room temperature, ≥500 MΩ at high temperature, and ≥20 MΩ after humidity testing. Electromagnetic components maintain ≥100 MΩ at room temperature, ≥50 MΩ at high temperature, and ≥10 MΩ after humidity.

Typical applications include launch vehicle umbilicals, aircraft external store separation, naval systems, and any application requiring flexible configuration with dual‑mode release.
