Half-Pitch Connector (for Board to Board Connections) - XH3

Caution
Product Description
A space saving type board-to-board connector without any screw mounting parts.
[Features]
· Supports a range of stacking heights from 12 mm to 20 mm.
· The contact pitch of 1.27 mm with a double-row arrangement allows for high-density mounting.
· The leaf contact construction enables smooth mating with excellent resistance to bending.
· A space saving mating length of 3.1 mm
· Press fit to assure a stable contact quality
· The use of gold/palladium plated contacts further improves contact reliability.
[Applications]
· Ideal for connections between boards.
