YFS8-6ZJ or TK Separation (Breakaway) Electrical Connector

YFS8-6ZJ/TK Separation (Breakaway) Electrical Connector | Water-Resistant up to 15m

The YFS8-6ZJ/TK Separation Connector series combines mechanical breakaway functionality with exceptional water resistance, making it ideal for applications where exposure to water or high humidity is a concern. When the receptacle is subjected to 15 m water pressure, each contact pair maintains full insulation integrity—ensuring reliable performance in marine environments, launch systems, and outdoor installations. With six 22# contacts rated at 5 A, solder termination, and a calibrated separation force of 10–20 N, the YFS8 series delivers dependable disconnect in a compact, rugged package. Whether used in naval separation mechanisms, aerospace deployment systems, or unmanned vehicles, the YFS8 provides the reliability that mission‑critical applications demand.

Product Descriptions from the Supplier

The YFS8-6ZJ/TK Separation (Breakaway) Electrical Connector is a precision‑engineered interconnect solution designed for applications requiring reliable electrical disconnection combined with outstanding environmental sealing. Fully compliant with enterprise standard Q/21EJ1273, this connector series features six 22# contacts rated at 5 A each, with a maximum contact resistance of 12 mΩ. Termination is via solder cups, providing a dependable, field‑serviceable connection suitable for prototyping, maintenance, and production.

A standout feature of the YFS8 series is its ability to withstand 15 m water pressure while maintaining insulation resistance between contacts and between contacts and shell—ensuring uninterrupted signal integrity in submerged or high‑humidity environments. The mechanical separation mechanism is calibrated to release with a force of 10–20 N, ensuring positive separation under commanded conditions while preventing inadvertent disconnect during handling or operation.

Engineered for harsh environments, the YFS8 series operates from -55 °C to +125 °C and survives severe dynamic conditions: random vibration of 0.04 G²/Hz (7.72 Grms), sinusoidal vibration of 150 m/s², shock peaks of 50 g (490 m/s²), and constant acceleration of 490 m/s². With a mechanical life of 500 mating cycles, these connectors are suitable for both ground testing and operational reuse.

Available in two configurations:

• YFS8-6TK: Plug with socket contacts (contacts accept pins)
• YFS8-6ZJ: Receptacle with pin contacts

Typical applications include naval separation interfaces, aerospace deployment mechanisms, missile launch systems, and any environment where water resistance and breakaway functionality are required.

FAQ

Q: What does "15m water pressure resistance" mean?
A: When the receptacle is subjected to a 15‑meter water head (approximately 1.5 bar), each contact pair maintains its insulation resistance, ensuring no electrical leakage or short circuits. This makes the connector suitable for submerged or high‑humidity applications.

Q: What is the separation force range?
A: The mechanical separation force is calibrated between 10 N and 20 N.

Q: How many contacts are available, and what is their rating?
A: There are six 22# contacts, each rated at 5 A with a maximum contact resistance of 12 mΩ.

Q: What termination method does this series use?
A: Termination is via solder cups, providing reliable, field‑serviceable connections.

Q: What is the operating temperature range?
A: The connector operates from -55°C to +125°C.

Q: Can the connector be reused after separation?
A: Yes, the mechanical life is rated for 500 mating/separation cycles, making it suitable for multiple tests and operational uses.

Q: What vibration and shock levels can it withstand?
A: It withstands random vibration of 0.04 G²/Hz (7.72 Grms), sinusoidal vibration of 150 m/s², shock of 50 g (490 m/s²), and constant acceleration of 490 m/s².

Q: What is the difference between YFS8-6TK and YFS8-6ZJ?
A: YFS8-6TK is the plug (cable‑attached half) with socket contacts; YFS8-6ZJ is the receptacle (panel‑mount half) with pin contacts.
