Molex Micro-Latch 1.25mm SMT Vertical Socket Connector Kit — Fine-Pitch PCB Assembly
The Molex Micro-Latch 1.25mm SMT vertical socket connector is a fine-pitch, surface-mount wire-to-board connector designed for compact PCB assemblies where space is at a premium. The 1.25mm pitch delivers a smaller footprint than JST XH (2.5mm) or PH (2.0mm) connectors, making it ideal for wearables, IoT sensors, and miniaturized embedded systems. Reflow solder compatible. This kit includes assorted pin-count SMT vertical socket housings and matching crimp terminals.
