The 0.8mm pitch board-to-board (BTB) dual-slot female connector is an interconnect component that balances connection density, stability and assembly tolerance. It is mainly used for board-to-board signal and power transmission in medium and high-end electronic devices. The combination of 0.8mm pitch and dual-slot locking structure achieves an ideal balance between space efficiency and anti-vibration performance.
1. Core Parameters & Structural Advantages
0.8mm Pitch Design
As a mainstream medium-precision pitch, it is easier for PCB routing and assembly alignment compared with 0.5mm pitch, reducing the risk of poor contact while enabling multi-contact layout in limited space.
Pin count ranges from 8PIN to 120PIN, with common configurations from 2×4P to 2×60P, supporting multi-channel signal and low-to-medium power transmission for modular integration.
Dual-Slot Locking & Female Structure
The dual-slot design provides two symmetrical upper and lower mating slots, offering dual-side positioning. Compared with single-slot types, it effectively resists horizontal displacement and vibration, preventing loosening or disconnection.
As a female connector, it is the passive mating side with contact sockets, and must be paired with a matching 0.8mm BTB male connector to form a complete transmission chain.
Stack height ranges from H3.0mm to H6.5mm, flexible for different board spacing designs.
Installation & Flexibility
Supports both SMT surface mount and DIP through-hole soldering, suitable for automated mass production as well as manual DIY or small-batch assembly.
Some floating versions offer ±0.60mm alignment tolerance in X and Y axes to absorb assembly errors and improve connection reliability.
2. Material & Core Performance
Contacts are made of phosphor bronze with gold or tin plating, delivering high conductivity, oxidation resistance and wear resistance.
