JST XH 4-Pin

The JST XH series is one of the most widely used wire-to-board connectors in electronics. This 4-pin vertical variant (B4B-XH-A) at 2.50mm pitch provides reliable, locking connections for battery packs, sensor cables, motor wiring, and inter-board communication. The XH series supports up to 3A per contact at 250V, making it suitable for both signal and moderate power applications. Ubiquitous in 3D printers (stepper motors, thermistors), RC/drone battery connections, and maker projects.
