Frequently Asked Questions
Q: What connector type do these SM-3PIN extension wires use?
A: These cables use SM-3PIN (3-pin) male and female lock connectors, commonly used in RC servos, LED strip lighting, and hobby electronics wiring. The connector shell snaps together firmly for a secure, vibration-resistant fit.
Q: What wire gauge are these servo extension cables?
A: The cables are 20AWG (American Wire Gauge), which provides a good balance of flexibility and current-carrying capacity for low-voltage servo, LED, and signal wire applications (rated below 50V AC or 75V DC).
Q: What lengths are available in the 5-piece set?
A: The cables come in two length options — 15 cm (approximately 5.91 inches) and 30 cm (approximately 11.81 inches) — making them suitable for both compact builds and slightly longer wiring runs inside RC models or DIY electronics projects.
Q: Are these cables compatible with RC car and aircraft servo connections?
A: Yes! These SM-3PIN connector extension wires are designed for use with RC cars, aircraft models, boats, LED wiring harnesses, and general hobby assembly or electronic repair tasks where a standard 3-pin connector is required.
