Product Description
The JST XH 2.54mm 4-Pin Female Connector Set with 20cm Wire is a convenient, pre-crimped cable assembly designed for instant, reliable wire-to-board connections in electronics and prototyping projects. Featuring a standard 2.54mm pitch female housing paired with four flexible 20cm insulated wires, it eliminates the need for tedious manual crimping and soldering during assembly.
Essential for wiring Nema 17 stepper motors, multi-cell battery balance leads, and custom peripheral modules, this cable harness plugs securely into standard JST XH male headers for dependable power and signal transmission.
⚠️ Polarity & Wiring Tip: Always verify your circuit’s pin assignment and color-code alignment against your target PCB header before plugging in power or signal lines to prevent reverse-voltage damage.
Technical & Architectural Highlights
Pre-Crimped & Ready to Use: Factory-crimped female terminals inside a durable plastic housing save valuable setup and preparation time.
Standard 2.54mm Pitch: Perfectly spaced to mate securely with standard JST XH male PCB headers and pin connectors.
Flexible 20cm Leads: Multi-strand insulated wires provide ample length for routing connections cleanly inside enclosures and chassis.
Reliable Contact Pressure: Precision metal spring terminals ensure low contact resistance and secure mechanical retention.
