Medical Field
Connectors suitable for life science applications must be reliable, robust, and easy to mate/unmate, while withstanding high temperatures, high humidity, and sterilization processes. Consistent performance and maximum protection against electrical breakdown are critical in the medical environment.
Our push‑pull connector series and cable assembly solutions have repeatedly proven themselves in this industry, which operates under the most stringent regulatory and normative requirements.
- Analyzers, process control instruments, pulse oximeters, fetal monitors, respiratory humidification systems, etc. – using push‑pull connectors Series B, K, and S.
- Dental instruments – using push‑pull connectors Series B, K, and P.
- Single‑use disposable devices (sensors, catheters) – using push‑pull connectors Series P.
Military & Aerospace
Circular connectors are primarily deployed in military vehicles, aircraft, naval systems, and ground support equipment. Their reliability is critical to the stable operation of equipment in combat environments and extreme climatic conditions. In addition, these connectors are also used in civilian applications that demand high reliability, such as aerospace, industrial automation, and telecommunications.
Overall, military circular connectors are of strategic importance in ensuring the readiness and operational effectiveness of military and aerospace systems. Their design and manufacturing fully comply with the stringent requirements of these sectors, making them indispensable components for achieving safe and efficient electrical connections.
Connector series that meet the needs of this field include Series B and Series K.


Test & Measurement Field
Precision measuring instruments and testing equipment require high‑quality connectors for signal transmission – for example, to transmit data from voltage, current, force, flow, pressure, and other test acquisitions, enabling measurement and testing functions in applications such as airport weighing systems and test monitoring systems.
Our push‑pull connector series solutions are designed to fully meet the need for interference‑free signal connections between sensors and measurement/test equipment in a wide variety of scenarios.
Connector series that meet the requirements of this field include Series B, Series K, Series S, and others.
Aerospace & Unmanned Aerial Vehicles (UAVs)
Civil aircraft, commercial aviation, military aviation, UAVs, GPS navigation, and other equipment require reliable signal and data transmission. Therefore, the ability to perform well in harsh environments is a fundamental requirement for connector solutions in this field.
Our push‑pull connector series and threaded circular connector solutions (including cable harnesses) are designed to operate reliably under extreme conditions such as low temperature, vibration, high radiation, and high humidity – fully meeting the needs of the aerospace and UAV sector.
The following connector series are available for aerospace and UAV applications: push‑pull connectors (including push‑pull self‑locking types) in Series B, Series K, Series S, and others.


Marine & Offshore Engineering
Marine and offshore engineering covers applications such as ships, yachts, ferries, cruise liners, radar, GPS navigation, autopilots, and more. Equipment in this field requires waterproof and corrosion‑resistant properties, especially for connectors. Tuyi's plastic screw‑nut locking mechanisms, along with plug‑in and quick‑lock structures, not only address waterproofing and corrosion resistance but also significantly reduce costs, saving installation time and labor.
Industrial Cameras, Broadcasting & Audio
Applications such as broadcast television cameras, control equipment, audio equipment, wireless microphones and microwave transmission for live broadcasts, studios, film, television, radio broadcasting equipment, theater, and music all require reliable connection solutions. In this field, connectors typically need to be easy to operate, space‑saving, and offer high mating cycle life.
Push‑pull connectors that meet the needs of this field include Series B, Series K, Series S, and others.
