Overview
The 2-Pin JST RCY Connector Pair is a highly reliable, polarized interconnect system designed for low-voltage electrical applications. This pack features one male and one female housing, each pre-crimped and soldered to 10cm of flexible, color-coded wire (Red/Black). The keyed, friction-locking design prevents accidental reverse-polarity hookups, making it the safest and easiest way to build disconnectable power lines for batteries, small motors, and custom PCB prototypes.
Key Features
Polarized Keyed Housing: The unique physical shape ensures it can only be plugged in one way—safeguarding your expensive microcontrollers from reverse-polarity damage.
Pre-Wired Convenience: No crimping tool required! Comes with pre-attached 10cm pigtail leads ready to be stripped, soldered, or heat-shrunk.
Secure Friction Lock: Provides a firm, vibration-resistant connection that won’t slide apart during movement, making it excellent for RC cars, planes, and mobile robots.
Standard Wire Gauge: Uses flexible 22AWG to 24AWG silicone/PVC insulated wire capable of handling standard low-power hobby electronics current loads.
