HRS BM28B0.6-10DS/2-0.35V(51)
Product Overview
The BM28 Series connectors offer a compact solution for board-to-board or board-to-FPC connections, featuring a 0.35mm pitch and a low profile of 0.6mm. They are designed to handle rated currents up to 5A for power contacts and 0.3A for signal contacts (with derating for higher contact counts). These connectors are suitable for a wide range of operating temperatures and humidity levels.
Key Features:
- 0.35mm pitch
- 0.6mm height
- Rated current up to 5A (Power Contact)
- Rated voltage 30V AC/DC
- Suitable for Board-to-Board and Board-to-FPC applications
