The YFS8‑52ZJ/TK Separation Connector series offers high‑density signal interconnection with proven underwater sealing capability. Featuring 52 solder‑terminated contacts—six 16# (10 A) and forty‑six 22# (5 A)—it provides ample capacity for complex signal and low‑power interfaces in a single breakaway package. The receptacle is engineered to withstand 15 m water pressure while maintaining insulation integrity, making it ideal for marine, offshore, and high‑humidity environments. With calibrated 50–100 N separation force, proven resistance to vibration and shock, and a 500‑cycle mechanical life, the YFS8‑52 delivers reliable performance in aerospace, naval, and defense separation events.
The YFS8‑52ZJ/TK Separation (Breakaway) Electrical Connector is a high‑density interconnect solution designed for applications requiring both multi‑circuit capability and outstanding environmental sealing. Fully compliant with enterprise standard Q/21EJ1273, this connector features 52 solder‑terminated contacts: six 16# contacts rated at 10 A each (≤30 mΩ) and forty‑six 22# contacts rated at 5 A each (≤50 mΩ). This hybrid arrangement allows system designers to combine control, signal, and low‑power circuits within a single separation interface.
A key 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 50–100 N, providing a secure hold during operation while ensuring positive separation when commanded.
Engineered for harsh environments, the YFS8‑52 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.
Dielectric withstanding voltage is 1000 V AC rms at sea level, derated to 500 V under humidity and 200 V at temperature extremes. Insulation resistance exceeds 1000 MΩ at room temperature and remains ≥20 MΩ after humidity and mechanical testing, ensuring long‑term reliability.
Available in two configurations:
Typical applications include naval separation interfaces, underwater vehicle tether release, aerospace deployment mechanisms, and any environment requiring high‑circuit‑count breakaway functionality with water resistance.

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 50 N and 100 N. (Note: some documentation may list an additional 28–50 N range; please confirm exact force with factory for your specific configuration.)
Q: How many contacts are available, and what are their ratings?
A: There are 52 contacts total: six 16# contacts rated at 10 A each (≤30 mΩ), and forty‑six 22# contacts rated at 5 A each (≤50 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 YFS8‑52TK and YFS8‑52ZJ?
A: YFS8‑52TK is the plug (cable‑attached half) with socket contacts; YFS8‑52ZJ is the receptacle (panel‑mount half) with pin contacts.
Q: What is the insulation resistance after environmental testing?
A: After humidity and mechanical testing, insulation resistance remains ≥20 MΩ, ensuring reliable signal transmission.
Q: Do you provide mating connectors?
A: Yes, both plug and receptacle versions are available. Please specify your configuration when ordering.
