JST XH 2.5mm 4-Pin Terminal Wire — 22AWG, SXH-001T-P0.6 Contact, 3A/250V

A precision pre-crimped terminal wire for JST XH 2.5mm connector systems, built with the genuine JST SXH-001T-P0.6 contact — the OEM-specified terminal for the XH series. One end carries a factory-crimped SXH-001T-P0.6 terminal ready to insert into any standard JST XH 4-pin housing; the other end is left bare for direct soldering, screw terminal connection, or custom termination. Four conductors cover the full range of common 4-wire interface protocols: I2C (SDA/SCL/VCC/GND), SPI (MOSI/MISO/SCK/CS), stepper motor phase pairs, and UART with hardware flow control.

The SXH-001T-P0.6 contact is the genuine JST-specified terminal for the XH series — not a generic substitute. Using the correct OEM contact ensures proper engagement with the housing latch, correct contact force against the mating pin, and full compliance with the XH series electrical ratings. For applications where connector reliability is critical, specifying the correct contact is as important as specifying the correct housing.

22AWG stranded copper wire rated at 3A/250V handles both signal and light power applications across the full 4-pin XH range.

Why the SXH-001T-P0.6 Contact Matters

The JST SXH-001T-P0.6 is the OEM-specified crimp terminal for the XH connector series. It features a precisely dimensioned crimp barrel sized for 22–28AWG wire, a contact beam geometry engineered to deliver the correct normal force against the mating pin, and a retention lance that locks positively into the XH housing. Generic terminals may fit physically but often deliver lower contact force, higher contact resistance, and reduced retention force — all of which degrade connection reliability over time. For production assemblies and any application where connector performance matters, the genuine JST contact is the correct specification.

Typical Applications

I2C Buses: OLED displays, RTC modules, IMU sensors, environmental sensors (BME280, SHT31), EEPROM connections
SPI Interfaces: SD card modules, display drivers, ADC/DAC breakouts, flash memory connections
3D Printers: Stepper motor phase wiring (X/Y/Z/E axes), BLTouch/CR Touch probe connections, filament sensor leads
Stepper Motor Drivers: Motor phase output connections (A1/A2/B1/B2), driver module wiring
