Product Descriptions from the Supplier

The YF8‑22aZJ/TK Separation (Breakaway) Electrical Connector is a compact, high‑density interconnect solution designed for applications requiring multiple signal circuits within a single separation interface. Fully compliant with enterprise standard Q/21EJ1292, this connector features 22 size‑22# contacts rated at 5 A each, making it ideal for discrete signals, low‑power circuits, and control interfaces.

All contacts are terminated via crimp technology, ensuring reliable, repeatable connections suitable for high‑volume production and field maintenance. The mechanical separation mechanism is calibrated to release with a force of 15–25 N, providing a secure hold during operation while ensuring positive separation when commanded.

Engineered for harsh environments, the YF8‑22a operates from -55 °C to +125 °C and survives severe dynamic conditions: random vibration of 0.3 g²/Hz, shock of 196 m/s², and constant acceleration of 490 m/s². With a mechanical life of 500 mating cycles, these connectors are suitable for ground testing and operational use.

Dielectric withstanding voltage is 1000 V AC rms at sea level, derated to 500 V under damp heat and 200 V under combined temperature extremes and low pressure (4.4 kPa). Insulation resistance exceeds 1000 MΩ at room temperature and remains above 20 MΩ after humidity and mechanical testing, ensuring long‑term reliability.

Available in two configurations:

• YF8‑22aTK: Plug with socket contacts (accepts pins)
• YF8‑22aZJ: Receptacle with pin contacts

Typical applications include launch vehicle umbilicals, avionics separation interfaces, UAV tether release, and any system requiring a dense array of signal circuits in a breakaway package.

FAQ

Q: What makes the YF8‑22a different from the YF8‑22?
A: The YF8‑22a is an all‑signal version with 22 identical 22# contacts (5 A each), while the YF8‑22 includes a mix of 22# contacts and differential pairs for high‑speed data. The YF8‑22a also has a lower separation force (15–25 N vs. 40–60 N) and shorter mechanical life (500 cycles vs. 1500 cycles).

Q: What is the separation force range?
A: The mechanical separation force is calibrated between 15 N and 25 N.

Q: How many contacts are there, and what are their ratings?
A: There are 22 contacts total, all size‑22#, 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 crimp for all contacts, providing reliable, production‑friendly connections.

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

Q: What vibration and shock levels can it withstand?
A: It withstands random vibration of 0.3 g²/Hz, shock of 196 m/s², and constant acceleration of 490 m/s².

Q: What is the difference between YF8‑22aTK and YF8‑22aZJ?
A: YF8‑22aTK is the plug (cable‑attached half) with socket contacts; YF8‑22aZJ is the receptacle (panel‑mount half) with pin contacts.
