A: L/T: 3-4 weeks.
Q: What is the maximum temperature rating for this 6.35mm terminal?
A: The maximum temperature rating is 105ºC
Q: Can this AWG12-10 receptacle be used in automotive vibration environments?
Yes, this AWG12-10 straight insulated female receptacle is suitable for automotive vibration environments.
It adopts internal locking structure and tight mating design to resist loosening under continuous vibration. Made of high toughness nylon insulation and tin-plated brass terminal, it maintains stable electrical connection and good anti-vibration performance, perfectly fit for automotive wiring harness and vehicle on-board applications.
Q: What is the difference between 4.75mm and 6.35mm connectors?
A: The main differences are tab width, current rating, wire gauge compatibility and application scenarios.
①4.75mm (0.187 inch)
Smaller size, for medium-low current, fits AWG22–14 wires. Compact structure for narrow installation space, commonly used in small home appliances and general electronic wiring.
②6.35mm (0.250 inch)
Larger tab width, higher current carrying capacity, supports AWG12–10 thick wires. More stable mating and better anti-vibration performance, widely used in automotive wiring harnesses, high-power home appliances and industrial equipment.
Simply choose 4.75mm for small current & compact layout; choose 6.35mm for high current, thick wire and automotive vibration environments.
Q: How do I choose the correct AWG size?
A: Select the connector based on your wire gauge. This product is designed for AWG12-10(3.31-5.26mm²) wires, ensuring a proper crimp fit.
Q: Are these connectors insulated?
A: Yes, they feature a fully insulated sleeve to prevent short circuits and improve safety.
Q: What wire size does AWG12-10 support?
A: This AWG12-10 insulated female terminal supports wire gauge AWG12 to AWG10, corresponding to cross-sectional area 3.31mm² ~ 5.26mm².
It is matched with thicker wires and designed for high-current wiring applications.
Q: What certifications do HRB connectors have (UL, RoHS, REACH)?
A: HRB connectors hold UL/cUL, RoHS, and REACH certifications, plus key automotive and industrial approvals.
UL/cUL: Certified under UL 1977 (file no. E322751)
Q: What is the difference between AWG12-10, AWG16-14 and AWG22-18? How to select the correct wire size?
A: The three ranges differ in wire cross-sectional area, current rating and application purpose.
①AWG22-18: Smallest wire size, thin conductor, for low current and general electronic & small appliance wiring.
②AWG16-14: Medium wire size, medium current load, commonly used in home appliances and standard automotive circuits.
③AWG12-10: Largest wire size, thick conductor, for high current, high-power equipment and heavy-duty automotive wiring harnesses.
Selection guide:
①Choose AWG22-18 for low-current ordinary circuits;
②Choose AWG16-14 for standard household and general automotive use;
③Choose AWG12-10 for high-current and high-power applications.
Q: What is the difference between loose piece packing and reel packing for terminals, and how to choose the right one?
A: Loose piece packing means terminals are supplied in bulk individual bags, while reel packing winds terminals on continuous plastic reels.
①Loose packing: For manual assembly, small-batch production, lab repair and maintenance; easy to take a small quantity at a time.
②Reel packing: For automatic crimping machines and high-volume mass production; compatible with automated wiring harness equipment to improve efficiency.
Choose loose packing for manual use and small orders; choose reel packing if you use automatic crimping equipment for large-scale production.
Q: Why are there three colors — red, blue, and yellow — for the same Straight Insulated Female Receptacle (M6350 series)?
A: The red, blue, and yellow colors in the M6350 series are industry standard color coding that indicates the compatible wire gauge (AWG) and cross‑section area. All other dimensions and electrical specs are identical.
①Red (R)：AWG22–18 (0.32–0.82 mm²)
②Blue (B)：AWG16–14 (1.30–2.08 mm²)
③Yellow (Y)：AWG12–10 (3.31–5.26 mm²)
This color system enables fast, error‑free selection during manual assembly and maintenance.
