HRS BM24-40DP/2-0.35V(51)
BM24 Series Hybrid Power/Signal Connectors
The BM24 Series offers 0.35mm pitch, 0.8mm height hybrid power/signal connectors designed for board-to-board and FPC-to-board applications. These connectors combine power and signal contacts to provide a compact and efficient solution.
Key Features:
- Hybrid design for integrated power and signal transmission.
- Low profile (0.8mm height) for space-constrained designs.
- 0.35mm pitch for high-density applications.
- Suitable for board-to-board and FPC-to-board connections.
