Product Specification

BTB Double Slot 0.8MM Vertical SMT Board-to-Board Connector Male & Female 4.0H-8.5H PCB Board Socket

Product Description

The board-to-board connector is the most powerful connector product of all connector products. It is mainly used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, etc. Military manufacturing and other industries. At present, the main spacing of board-to-board connectors is 0.4mm 0.5mm, 0.8mm, 1.00m, 1.27mm and so on.

Feature

1. Space-Saving Vertical PCB Connection

The vertical SMT board-to-board design allows two PCBs to be connected in a stacked configuration, making it suitable for products where PCB space is limited.

Typical applications:

• Compact embedded systems
• Industrial controllers
• Smart devices
• Portable electronic equipment

2. Flexible Stacking Height Options

The connector supports multiple mating heights:

4.0mm / 4.5mm / 5.0mm / 5.5mm / 6.0mm / 6.5mm / 7.0mm / 7.5mm / 8.0mm / 8.5mm

This allows engineers to select suitable PCB spacing according to enclosure structure and internal component layout requirements.

3. SMT Manufacturing Compatibility

The SMT terminal design supports automated surface mounting processes, helping simplify PCB assembly and improve production efficiency.

Common SMT BTB connectors use tape-and-reel packaging options for automated placement equipment.
