Applications

1. Aerospace and Launch Vehicles: Used for rocket stage separation, satellite-launch vehicle separation, and fairing jettison. Upon receiving the separation command, the connector disengages rapidly, ensuring the spacecraft follows its predetermined flight sequence.
2. Missile Weapon Systems: During missile launch, it connects ground test equipment to onboard equipment and automatically disengages at launch to achieve electrical isolation.
3. Aviation and Unmanned Aerial Vehicles (UAVs): Used for electrical connections between pylons and weapons (or auxiliary fuel tanks), disengaging upon release.
4. Specialized Industrial Equipment: Used in large automated machinery for modules requiring quick changeover or for emergency disconnect mechanisms.

Key Features

1. Number of Contacts: Configurable according to user requirements, often ranging from dozens of contacts for transmitting control signals, power, and data.
2. Rated Voltage/Current: Depending on the contact specifications, it typically covers signal-level (mA range) to power-level (several amperes to tens of amperes).
3. Insulation Resistance: Under standard atmospheric conditions, typically not less than 1000 MΩ (or higher).
4. Dielectric Withstanding Voltage: Depending on circuit requirements, it can typically withstand voltages from 500V AC to over 1500V AC.
5. Mechanical Life: Under non-separation conditions, the mating cycle life is typically 500 times or more; the separation function is generally designed for single-use or limited cycles (depending on the specific triggering mechanism).
6. Environmental Adaptability: The operating temperature range typically covers -55°C to +125°C (or higher), with excellent resistance to high/low temperatures, humidity, and vibration.
