Product Overview:
0.4mm B-to-B Battery Connectors
This series of connectors is designed for high-performance, ultra-thin, high-current board-to-board (BTB) connections in consumer electronics like smartphones, tablets, and smart wearables. It combines an
ultra-fine 0.40mm pitch with powerful high-current transmission capability, delivering high reliability power in an extremely compressed space.
The product includes the GY046P series male header (plug) and the REC H0.93 series female receptacle (socket).
0.4mm Pitch Battery Connectors Key Features:
1. Ultra-Low Profile & Space Saving:
• An exceptionally low mated height of just 0.98mm, catering to the ultimate pursuit of thinness in modern smart devices.
• The 0.4mm B-to-B Battery Connectors 0.40mm pitch results in an effective pin width of only 4.40mm for 24 PINs.
2. High Current Power Transmission:
• Specifically designed for battery power transmission, reliably handling high currents at a rated voltage of 50V AC/DC, meeting the needs of high-power devices.
3. High-Reliability Contact Plating:
• Terminals are made of high-performance Copper Alloy.
• The full gold plating process (Terminal: Gold Plating Nickel Min. Over All) effectively reduces contact resistance and provides superior anti-corrosion and anti-oxidation performance.
4. Excellent Mechanical & Environmental Performance:
• Wide Temperature Range: Operates stably in harsh environments from to .
• High Insulation Performance: Insulation resistance of at least , withstanding voltage of for one minute, ensuring safety in use.
