FAQs about circular plastic connectors
Weipu WK16 Series Industrial Lock Hook Connectors with IP67 Protection
How to choose between PPE and Zinc alloy shell?
It is recommended to choose according to the use environment: PPE shell is lightweight, corrosion-resistant and cost-effective, suitable for general industrial environments and home use scenarios; Zinc alloy shell has higher mechanical strength and impact resistance, suitable for harsh environments with frequent collision and vibration, such as construction machinery and outdoor heavy-duty equipment.
What is the advantage of the lock hook connection of the WK16 Series compared to other coupling methods?
The lock hook connection of the WK16 Series has the advantages of tool-free operation, quick mating and disconnection, and simple operation. It can be completed with one hand, which is more efficient for scenarios requiring frequent disassembly and maintenance. At the same time, the lock hook has a self-locking function, which can ensure stable connection without loosening under vibration conditions.
Is it necessary to choose the EMC shielding function?
It depends on the use scenario. If the connector is used in a complex electromagnetic environment (such as near high-power electrical equipment, frequency converters, etc.), it is recommended to choose the EMC shielding function, which can effectively reduce electromagnetic interference and ensure stable signal transmission; if it is used in a simple electromagnetic environment, the standard version without shielding can meet the requirements.
