JST XH 2.5mm 3-Pin Connector with 22AWG Pre-Crimped Cables — Housing, Header & Wire

JST XH 2.5mm 3-Pin Connector Kit — Housing, PCB Header & 22AWG Pre-Crimped Cables

Everything you need to build a complete, professional-grade 3-pin JST XH 2.5mm connector assembly in a single kit. This package combines the female housing (plug), the male PCB header (socket), and factory pre-crimped 22AWG cables — eliminating the need to source three separate components and ensuring full compatibility between all parts.

The 3-pin XH format is one of the most widely used connector configurations in electronics: thermistor leads, servo extensions, I2C sensor modules (SDA/SCL/GND), UART breakout connections (TX/RX/GND), and RGB LED wiring all use this exact pin count. Having a complete kit on hand means you can build, repair, or extend any of these connections without waiting for additional parts.

Factory pre-crimped cables eliminate the most failure-prone step in connector assembly. Each terminal is machine-crimped to a defined pull-force specification — producing consistent, reliable connections that hand-crimping cannot match. The positive latch lock on the housing ensures the connector stays seated under vibration and repeated handling.

Why a Complete Kit Matters

Sourcing connector housings, PCB headers, and pre-crimped cables separately introduces compatibility risk — slight dimensional variations between manufacturers can result in housings that don't seat fully, contacts that don't engage properly, or headers that don't fit the PCB footprint. This kit is assembled from matched components that are verified to work together, eliminating compatibility guesswork and reducing assembly time.

Typical Applications

• 3D Printers: Thermistor lead assemblies, hotend fan connections, endstop switch wiring, filament runout sensor leads
• Arduino & Microcontrollers: I2C sensor module connections (SDA/SCL/GND), UART breakout wiring (TX/RX/GND), analog sensor leads
• Servo Systems: Standard servo connections (signal/power/ground), gimbal motor wiring
• RC & Drones: Flight controller sensor leads, GPS module connections, telemetry wiring
• Robotics: Encoder signal leads, limit switch connections, proximity sensor wiring
• Industrial & IoT: RS-485 bus connections, temperature sensor leads, panel instrument wiring
• Prototyping & Repair: Custom harness assembly, connector repair, breadboard-to-PCB connections

Compatibility

Compatible with all standard JST XH series 3-pin pre-crimped cables and PCB headers at 2.5mm pitch. The locking geometry is consistent with the JST XH standard, ensuring interchangeability with other XH-compatible components.
