Question you may concern
What is the difference between version I and II of SA series in cable outer diameter?
Version I and II correspond to different cable outer diameter ranges, which are designed to match cables of various thicknesses for more flexible installation.
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.
What does the IP67 rating of the WF Series connectors mean?
The IP67 rating indicates two key protection levels: "6" means complete protection against dust ingress (no dust can enter the connector), and "7" means protection against temporary immersion in water (it can be immersed in water up to 1 meter deep for 30 minutes without damaging the internal components or affecting performance).
Why does the ST Series only adopt solder termination?
The ST Series is mainly positioned for scenarios requiring high connection reliability. Solder termination can form a permanent and firm connection between the contact and the cable, which has lower contact resistance and better connection stability than other termination methods. It can effectively avoid connection failure caused by vibration and other factors, and is more in line with the use requirements of high-reliability scenarios.
