FAQ:

What is the benefit of silver-plated contacts?

Silver plating reduces contact resistance (≤2.5mΩ), minimizing energy loss and ensuring stable signal transmission, which is critical for precision equipment like LED displays.

What is the specific waterproof performance of the Weipu TYPR-231 connector's IP44 rating?

The IP44 rating of the TYPR-231 connector consists of two digits: the first digit "4" means it can prevent the intrusion of solid foreign objects ≥1.0mm; the second digit "4" means it can resist splashing water from any direction. It is suitable for daily industrial environments with general dust and splashing water, and is not applicable to scenarios such as heavy rain, long-term immersion in water or heavy dust.

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 difference between different crimping methods?

Screw crimping: easy to adjust; Cold crimping: high connection tightness; Spring clip crimping: quick operation, suitable for frequent disassembly.

Can the WD28 series be used in long-term high-temperature environments above 85°C?

No. The normal operating temperature range of the WD28 series is -40°C~+85°C, and the PPS insert can only withstand short-term high-temperature impacts up to 260°C (not long-term continuous high temperature). If it is used in a long-term high-temperature environment above 85°C, it is recommended to customize the upgraded high-temperature resistant insert or select other special high-temperature series products.
