YFS8-15ZJ or TK Separation (Breakaway) Electrical Connector

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

The YFS8‑15ZJ/TK Separation Connector series expands our water‑resistant breakaway family with a high‑density 15‑contact configuration. Combining four 16# power/signal contacts (10 A) and eleven 22# signal contacts (5 A), it offers exceptional design flexibility for complex separation interfaces. Like its 6‑contact counterpart, this version maintains full insulation integrity when the receptacle is subjected to 15 m water pressure—ideal for marine, offshore, and high‑humidity environments. With a calibrated separation force of 50–100 N, solder termination, and proven resistance to severe vibration and shock, the YFS8‑15ZJ/TK delivers reliable performance in the most demanding aerospace and naval separation events.

Product Descriptions from the Supplier

The YFS8‑15ZJ/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 15 solder‑terminated contacts: four 16# contacts rated at 10 A each (≤8 mΩ) and eleven 22# contacts rated at 5 A each (≤12 mΩ). This hybrid arrangement allows system designers to combine power, control, and signal 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 YFS8‑15 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:

• YFS8‑15TK: Plug with socket contacts (accepts pins)
• YFS8‑15ZJ: Receptacle with pin contacts

Typical applications include naval separation interfaces, aerospace deployment mechanisms, missile launch systems, and any environment where high‑circuit‑count breakaway functionality with water resistance is 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 50 N and 100 N.

Q: How many contacts are available, and what are their ratings?
A: There are 15 contacts total: four 16# contacts rated at 10 A each (≤8 mΩ), and eleven 22# contacts rated at 5 A each (≤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 YFS8‑15TK and YFS8‑15ZJ?
A: YFS8‑15TK is the plug (cable‑attached half) with socket contacts; YFS8‑15ZJ 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.
