[Product Overview] 2.5mm Pitch Horizontal SMT Side-Insertion Type (SMT 90-Degree High-Current Low-Profile) WAFER Header Wire-to-Board Connector

2.5mm Pitch Horizontal SMT Side-Insertion Type WAFER Header (High-Current Horizontal Wire-to-Board Connector) It is specifically designed for side-exit wiring at enclosure edges, height-constrained spaces, and high-power power/signal transmission, featuring a 90-degree SMT surface-mount base socket。

This product adopts a 90-degree horizontal side-entry (Right Angle SMT) structurethat, when mating with wire harnesses, runs parallel to the PCB surface, significantly reducing vertical space occupation (Profile Height). The 2.5mm pitch delivers robust electrical carrying capacity (up to 4.0A per pin) and ample creepage distance. Both ends are equipped with thickened SMT metal reinforcement fixing tabs, capable of withstanding extremely high lateral pull-out forces, effectively protecting PCB pads from damage caused by vibration or rough insertion/removal. The header incorporates a precision keyed polarization slot, completely eliminating the risk of blind or reverse insertion on the production line, and is 100% compatible with standard 2.5mm pitch crimp terminal housing wire harnesses on the market (such as the JST XH 2.5 horizontal SMT series), making it a cost-effective domestic alternative for high-current side-exit wiring in power boards, smart home appliances, and industrial equipment.

[Core Value and Procurement Decision Factors for Different Customer Segments]

1. For appliance, power, and structural engineers: low profile + 4A high current, optimized side-exit space

Side-entry wiring saves vertical space while delivering 4.0A high current capacity and high voltage resistance, making it ideal for slim white goods housings, modular side-plug interfaces, and edge layouts on high-power control boards.

2. To SMT PE process and wire harness processing plants: Reinforced solder pads resist tearing, and flat pins ensure trouble-free reflow soldering

High-conductivity copper PIN terminals and thickened fixed solder pads maintain coplanarity within 0.10mm, ensuring robust SMT soldering; during wiring, guidance is smooth and pull-out force is stable, effectively boosting production line assembly efficiency.

3. To procurement and BOM optimization managers: Benchmarking against JST XH2.5 horizontal mount, offering significant cost reduction and stable supply

Pin layout perfectly matches the JST XH 2.5 horizontal mount header, allowing direct replacement of imported brands without PCB modification, greatly shortening supply chain lead times and lowering procurement costs.
