YF6A-12ZK or TJ Separation (Breakaway) Electrical Connector

YF6A-12ZK/TJ Separation (Breakaway) Electrical Connector | Hybrid High-Current & Signal Contacts

The YF6A-12ZK/TJ Separation Connector series represents a breakthrough in hybrid interconnect design, integrating both high‑current power contacts and sensitive signal circuits within a single, rugged separation interface. With three independent separation modes—mechanical, electromagnetic, and handwheel—this connector offers unparalleled flexibility for mission‑critical applications ranging from spacecraft deployment to naval launch systems. The four Φ10 contacts deliver up to 200 A each, while the eight Φ1 signal contacts handle 5 A, all with ultra‑low contact resistance (≤5 mΩ). Solder termination ensures reliable field connections, and the entire assembly is qualified to withstand severe vibration, shock, and acceleration. When your system demands both power and signal in a breakaway package, the YF6A series delivers.

Product Descriptions from the Supplier

The YF6A-12ZK/TJ Separation (Breakaway) Electrical Connector is a sophisticated interconnect solution engineered for applications requiring both high‑current power transmission and reliable signal circuits within a single separation interface. Fully compliant with enterprise standard Q/21EJ1438, this connector features a hybrid contact arrangement: eight Φ1 contacts rated at 5 A each for signal or low‑power circuits, and four Φ10 contacts rated at 200 A each for primary power distribution. All contacts maintain an exceptionally low contact resistance of ≤5 mΩ, ensuring minimal power loss and signal attenuation.

A defining feature of the YF6A series is its triple‑mode separation capability:

• Mechanical separation via calibrated breakaway force (30–90 N)
• Electromagnetic separation using an integrated solenoid, activated by a 25–31 V DC pulse (≥200 ms) with separation occurring in ≤0.1 s
• Handwheel separation for manual override during ground handling or emergency situations

This multi‑mode flexibility makes the YF6A ideal for systems requiring redundant release mechanisms, such as spacecraft stage separation, missile launch interfaces, and naval deployment systems.

Termination is via solder cups, providing dependable, field‑serviceable connections suitable for both prototyping and production. The connector is built to survive extreme environments: operating temperature from -55 °C to +125 °C, random vibration of 0.3 G²/Hz (20 Grms), sinusoidal vibration of 196 m/s², shock peaks of 735 m/s², and constant acceleration of 490 m/s². With a mechanical life of 500 mating cycles, the YF6A series is suitable for repeated ground testing and operational reuse.
