The 5806 Series are Board to Board Connectors with a fine pitch of 0.4mm and an ultra-low stacking height of 0.6mm. These products feature the width of 1.9mm on the short side, which contributes to downsizing in small electronic equipment. An original locking structure generates a firm 'click' sound and enhances the retention force despite the slim and low profile, and peeling strength against printed circuit boards is strengthened by equipping metal tabs. In addition, a pinching structure (two-point contact design) has been adopted to enhance resistance to vibrations and drop shocks, thus ensuring high contact reliability.
