Technical Specifications of Right-Angle Circular Connector​

✔ Precision Threaded Coupling – Ensures firm locking without loosening, adapting to high-vibration industrial scenarios such as heavy machinery and production lines, guaranteeing continuous and stable connection.

✔ Black Nickel Plated Zinc Alloy Shell – Combines strong corrosion resistance and wear resistance, adapting to humid, salty, and lightly corrosive industrial environments; the black nickel plating offers an elegant appearance, suitable for high-end industrial equipment matching.

✔ High-Conductivity Gold-Plated Contacts – Gold-plated brass material minimizes contact resistance, reduces electrical signal/power transmission loss, and enhances anti-oxidation ability, ensuring long-term stable electrical performance.

✔ High-Temperature Resistant PPS Inserts – With a maximum temperature resistance of 260°C, it can withstand short-term high-temperature impacts in industrial equipment (such as industrial ovens and high-temperature pipelines), avoiding insert deformation or connection failure.

✔ Reliable Solder Termination – Solder connection ensures tight bonding between cables and contacts, with strong structural stability, not easily affected by external vibration or impact, suitable for fixed wiring in industrial equipment.

✔ Wide Temperature Adaptability – Stable operation in the temperature range of -40°C~+85°C, adapting to extreme low-temperature and high-temperature industrial working conditions such as northern outdoor facilities and high-temperature workshops.

✔ High Insulation Safety – Insulation resistance up to 2000MΩ, effectively preventing electrical leakage and short-circuit faults, ensuring the safety of operators and equipment in industrial power supply and control systems.

Detailed Specifications of Right-Angle Circular Connectors​

Versatile Applications of Right-Angle Circular Connectors​

Industrial Automation Production Lines
Ideal for connecting PLC controllers, servo drives, and industrial sensors in high-vibration production lines. The precise threaded coupling ensures no loosening during equipment operation, and the high insulation performance guarantees the stability of the control system.
Heavy Machinery Equipment
Applied to the electrical connection of construction machinery, mining equipment, and agricultural machinery. The black nickel-plated zinc alloy shell resists humidity, dust, and mild corrosion in outdoor harsh environments, ensuring long-term reliable operation of the equipment.
High-Temperature Auxiliary Equipment
Used for the connection of control components in industrial ovens, high-temperature pipelines, and other short-term high-temperature equipment. The PPS inserts with high temperature resistance prevent connection failure caused by high-temperature impact.
Outdoor Industrial Facilities
Suitable for electrical connection of outdoor monitoring equipment, power distribution boxes, and communication terminals in cold regions (not applicable to coastal high-salt fog environments). The wide temperature adaptability meets the needs of harsh outdoor low-temperature environments.
Electrical Control Cabinets
Used for wiring of internal components in high-end industrial control cabinets. The elegant black nickel-plated appearance matches the high-end equipment, and the reliable solder termination ensures the safety and stability of the internal electrical system.

Superior Advantages of the Right-Angle Circular Connector

Superior Corrosion Resistance & Aesthetic Appearance
The black nickel-plated zinc alloy shell not only has stronger corrosion resistance than ordinary zinc alloy shells (especially suitable for humid and salty environments) but also has an elegant and textured appearance, realizing the dual advantages of practicality and aesthetics, which is more competitive in high-end industrial equipment matching.
High Stability in Harsh Environments
The combination of precise threaded coupling and high-quality materials ensures stable operation under high vibration, extreme temperature, and corrosion conditions. Compared with snap-on connectors, it has better anti-loosening performance and longer service life in harsh industrial environments.
Efficient & Reliable Electrical Transmission
Gold-plated brass contacts minimize transmission loss, ensuring the accuracy of industrial control signals and the stability of power supply. The high insulation resistance further avoids electrical safety hazards, which is more reliable than ordinary connectors in high-power industrial scenarios.
Strong Scenario Adaptability
With wide temperature adaptability and high-temperature resistant inserts, it can be applied to multiple industrial scenarios such as low-temperature outdoor, high-temperature workshops, and humid coastal areas, reducing the cost of customers selecting different connectors for different scenarios.
Professional Brand Assurance
Backed by Weipu's nearly 30 years of industrial connector R&D and manufacturing experience, it has a strict quality control system and comprehensive after-sales service, which is more trustworthy than small-brand products.

FAQs about Right-Angle Circular Connectors

Weipu WB Series Industrial Threaded Connectors
Benefits of chrome-plated zinc alloy shell?

Chrome boosts corrosion resistance; zinc alloy provides high strength — fitting humid/lightly corrosive environments & resisting impacts.

What’s the advantage of threaded coupling for industry?

It locks precisely, maintaining firm connections in high-vibration scenarios (e.g., heavy machinery) — more stable than snap-on coupling here.

What does PPS insert’s 260℃ max mean?

It refers to short-term high-temp resistance — handling transient heat in industrial equipment (not long-term continuous high temps) to avoid deformation.
