YFS8-24ZJ-01 or TK-01 Separation (Breakaway) Electrical Connector

YFS8-24ZJ-01/TK-01 Separation (Breakaway) Electrical Connector | 30m Underwater Sealed, 24-Contact Hybrid Interface

The YFS8‑24ZJ‑01/TK‑01 Separation Connector series takes underwater reliability to the next level, offering certified sealing at 30 m depth for both mated and unmated conditions. With 24 hybrid contacts—four 16# (10 A) and twenty 22# (5 A)—it delivers ample capacity for power and signal circuits in a single breakaway interface. Solder termination ensures field‑proven dependability, while the calibrated 50–100 N separation force (with 15° angular tolerance) guarantees positive release even in non‑ideal pull directions. Qualified to rigorous vibration, shock, and acceleration standards, the YFS8‑24‑01 is the preferred choice for submarine-launched systems, underwater vehicles, and aerospace applications where water ingress is not an option.

Product Descriptions from the Supplier

The YFS8‑24ZJ‑01/TK‑01 Separation (Breakaway) Electrical Connector is a high‑performance interconnect solution engineered for the most demanding underwater and aerospace separation events. Fully compliant with enterprise standard Q/21EJ1273, this connector features a unique dual‑seal design that maintains IP68‑equivalent protection at 30 m water depth when mated, and ensures the receptacle alone can withstand 30 m water pressure for over 50 hours without internal shorting (insulation resistance ≥2 MΩ during and after exposure).

The contact complement consists of four 16# contacts rated at 10 A (≤8 mΩ) for moderate power or control circuits, and twenty 22# contacts rated at 5 A (≤15 mΩ) for signal and low‑power applications—a total of 24 circuits in a compact shell. All contacts are terminated via solder cups, offering reliable, field‑serviceable connections suitable for prototyping, maintenance, and production.

Mechanical separation is calibrated to 50–100 N, with the unique ability to tolerate a 15° off‑axis pull angle, ensuring reliable release even when cable routing is not perfectly aligned. The connector withstands severe dynamic environments: random vibration (0.04 G²/Hz from 10–1000 Hz, then –6 dB/oct to 2000 Hz, 7.72 Grms), sinusoidal vibration of 150 m/s², shock of 50 g, and constant acceleration of 490 m/s². With a mechanical life of 500 mating cycles, it is suitable for repeated ground testing and operational reuse.

Available in two configurations:

• YFS8‑24TK‑01: Plug (cable‑attached half) with socket contacts
• YFS8‑24ZJ‑01: Receptacle (panel‑mount half) with pin contacts

Typical applications include underwater vehicle tether release, submarine‑launched systems, naval buoy deployment, and aerospace stage separation where water exposure is a critical concern.
