R35K Series Board-To-Board Fine-Pitch Connectors

Panasonic R35K series 4-pin and 6-pin connectors are ideal for lightweight battery-powered devices such as smartwatches, hearing aids, and headphones

Image of Panasonic R35K Series Board-To-Board Fine-Pitch ConnectorsThe Panasonic R35K series is an ultra-small 0.35 mm pitch socket and header connector pair, available in 4-pin and 6-pin solutions. These connectors use power terminals at each end to transmit a continuous 3 A current, enabling the connection of small battery-powered devices. The inner pins of the connectors are each rated 300 mA for carrying signals.

The R35K series connector maintains the unique Panasonic Tough Contact construction, consisting of bellowed contacts for shock and vibration resistance, and a V-notch construction shape that maintains two points of contact between the socket and header pins. The robust structure and balancing of small size and high current capability make the R35K series ideal for lightweight battery-powered devices such as smartwatches, hearing aids, and headphones.

Features
