Kyocera Corp. announced its new 5811 series board-to-board connectors have been miniaturized to be about 50% smaller than conventional products and optimized for wearable devices. The 5811 Series connectors feature a 0.35 mm-pitch to save space, perform well in high current and are highly durable. Samples are available globally now.

The demand for wearable devices such as wireless headphones and smart glasses continues to increase. Global production of wireless headphones in 2025 is expected to increase to 570 million*1, approximately 2.7 times larger than 2019 production levels.

Kyocera’s new 5811 series board-to-board connectors’ miniaturized size (1.7 mm width x 3.6 mm length) is optimized for wearables, handheld game consoles and other smaller electronics. The flat stacking structure maintains durability, workability when stacking, and reduction of damage despite its low 0.6mm stack height. In addition, it is resistant to the high current required for connectors which is a suitable design for battery connection.

Main features include

1. Space-saving, high-current and high durability for wearable devices — Despite its ultra-compact design, it is highly durable and optimized to perform in high current (3A/Power Terminal). The plug stacking surface has an even, flat shape, and the receptacle is concave shape with no central convexity to improve insertion guidance and prevent damage during mating. To meet customer demands for wearable devices, the 5811 series can accommodate 1-5 signal pins and 2 power pins.
2. Audible click and high retention force — New 5811 Series clicks during stacking to ensure proper mating. In addition, it does not easily detach due to the high retention force.
3. RoHS and Halogen-free compliant
