Technical Specifications of waterproof circular connectors​​

✔ Efficient Bayonet Coupling – Tool-free one-handed quick locking/disconnection, completes coupling in 1-2 turns, improving on-site installation and maintenance efficiency, suitable for scenarios requiring frequent disassembly (e.g., CNC lathe maintenance).

✔ Dual Shell Material Options – Nylon 66 shell: lightweight, corrosion-resistant, and cost-effective, suitable for clean/low-vibration scenarios (e.g., LED displays, food packaging machinery); Zinc alloy shell: high mechanical strength and anti-vibration, adapting to high-load/high-vibration scenarios (e.g., load-bearing machines, die-casting machines).

✔ High-Temperature Resistant PPS Inserts – Max temperature resistance 260℃, can withstand short-term high-temperature radiation from die-casting machines and other equipment, avoiding insert deformation or connection failure.

✔ 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 operation of precision equipment (e.g., CNC lathes, LED displays).

✔ Three Flexible Termination Methods – Solder termination (for Φ1mm、Φ2mm、Φ3mm contacts): suitable for fixed wiring of precision components; Screw termination (only for Φ3mm contacts): easy to disassemble and maintain,Compatible with food packaging machinery; Crimp termination: efficient and fast, suitable for large-scale assembly lines.

✔ Wide Temperature Adaptability – Stable operation in the range of -40℃~+85℃, adapting to extreme low-temperature workshops and high-temperature environments near die-casting machines.

✔ Durable Mating Performance – 500 mating cycles, meeting the frequent disassembly and maintenance needs of industrial equipment (e.g., load-bearing machine inspection, CNC lathe maintenance).

Detailed Specifications of circular waterproof connectors​

Versatile Applications of waterproof circular connectors​

LED Displays
Applied to the electrical connection of LED display modules and control systems. The nylon 66 shell is lightweight and corrosion-resistant, and the gold-plated contacts ensure stable signal transmission, avoiding display screen flicker; the quick bayonet coupling facilitates on-site installation and maintenance of large displays.
Food Packaging Machinery
Used for the wiring of electrical control components and driving parts of food packaging machinery. The zinc alloy/nylon 66 shell meets the clean and hygienic requirements of food processing environments; the screw termination is easy to disassemble and maintain, and the wide temperature adaptability adapts to the temperature changes of packaging machinery during operation.
Load-Bearing Machines
Applied to the electrical connection of load-bearing machine sensors and control systems. The zinc alloy shell has high mechanical strength and anti-vibration performance, ensuring that the connection does not loosen under high-load vibration; the reliable termination methods guarantee the safety and stability of the load-bearing control system.
Die-Casting Machines
Used for the connection of die-casting machine temperature control modules and power components. The PPS insert with high temperature resistance withstands the short-term high-temperature radiation near the die-casting machine; the zinc alloy shell resists high-temperature aging, ensuring long-term reliable operation in high-temperature working conditions.
CNC Lathes
Applied to the electrical connection of CNC lathe servo systems and precision control components. The gold-plated contacts ensure the accuracy of control signals, improving the machining precision of the lathe; multiple termination methods can be selected according to the internal wiring needs of the lathe, enhancing installation flexibility.

Superior Advantages of circular waterproof connectors​

Scenario-Exclusive Adaptability
Tailor-made for five core industrial scenarios, with dual shell materials and three termination methods precisely matching the working conditions of different equipment (e.g., clean requirements of food packaging machinery, high vibration of load-bearing machines), avoiding the trouble of mismatched general connectors.
Flexible & Efficient Installation
The bayonet coupling realizes tool-free quick installation, and the three termination methods cover the needs of precision wiring, maintenance-friendly wiring, and large-scale assembly lines, improving installation efficiency by 40% compared with traditional connectors.
Durable & Reliable Performance
Dual high-quality shell materials, gold-plated contacts, and high-temperature resistant PPS inserts form a stable structural system, which can adapt to temperature changes, vibration, and other harsh conditions; 500 mating cycles reduce the frequency of connector replacement and maintenance costs.
Precise Signal Transmission
Gold-plated brass contacts minimize signal loss, ensuring the control precision of CNC lathes and the display stability of LED screens. Compared with ordinary brass contacts, the signal transmission accuracy is improved by 30%.
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 in key industrial equipment connection scenarios.

FAQs about waterproof circular connectors​

Weipu WP20 Series Bayonet Connectors (Bilingual Version)
What are the applicable scenarios for the three termination methods of WP20 series?

Solder termination (Φ1mm、Φ2mm、Φ3mm): Suitable for precision components that require stable and fixed connection (e.g., LED display modules, CNC lathe servo components); 2. Screw termination (only Φ3mm): Suitable for scenarios that require frequent disassembly and maintenance (e.g., food packaging machinery control panels); 3. Crimp termination: Suitable for large-scale assembly line production (e.g., batch production of food packaging machinery), with high installation efficiency.

Can the WP20 series be used in the high-temperature environment of die-casting machines for a long time?

No. The PPS insert of the WP20 series can only withstand short-term high-temperature radiation up to 260℃ (not long-term continuous high temperature). The normal operating temperature range of the product is -40℃~+85℃. For the long-term high-temperature environment near die-casting machines, it is recommended to use heat insulation protection measures or select special high-temperature series products.

Is the WP20 series suitable for the high-vibration working condition of load-bearing machines?

Yes. The WP20 series with zinc alloy shell is specially adapted to high-vibration scenarios. The bayonet coupling mechanism can ensure firm locking without loosening under high-load vibration, and the high-strength zinc alloy shell can resist the impact of vibration, ensuring the stable operation of the load-bearing machine control system.
