Technical Specifications of Gold-Plated Electrical Contacts

✔ 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).

FAQs about gold-plated electrical contacts

HSK-Metric Nylon Cable Gland
What is the difference between 304 stainless steel and nickel-plated brass materials?

304 stainless steel has better corrosion resistance, especially suitable for marine salt spray and chemical environments; nickel-plated brass has excellent conductivity and cost-effectiveness, suitable for general industrial environments. Choose according to the corrosion level and budget of the working environment.

Can I get samples before placing a bulk order?

Yes. We provide free samples of standard products (you only need to bear the shipping cost). For customized products, sample fees and shipping costs need to be borne, and the sample fee can be deducted from the bulk order payment.

Which thread standard should I choose for my equipment?

It is recommended to confirm the equipment's origin and interface specification first. Metric thread is suitable for European equipment, PG thread for German standard motors/control cabinets, and NPT thread for American standard high-pressure equipment. Our technical team can also provide matching suggestions based on your equipment parameters.

What is the service life of Weipu cable glands and how to maintain them?

Under standard working conditions, the service life is more than 5 years. Daily maintenance only needs to regularly check the sealing ring wear and cable clamping status, keep the product clean, and avoid collision damage to the thread and locking structure. It is not recommended to disassemble frequently without necessity.
