SS4/ST4 0.40mm Ultra-Fine-Pitch Connectors

Samtec SS4 / ST4 0.40mm Ultra-Fine-Pitch Connectors deliver up to 28Gbps performance and are available with up to 100 I/Os and stack heights ranging from 4mm to 6mm. These slim-footprint connectors are designed for board-to-board connections where space is at a premium. The connectors are manufactured on an ultra-fine 0.40mm pitch and come in a vertical configuration. These Razor Beam™ LP family connectors are engineered to save space on the X, Y, and Z axes. The SS4 sockets mate with the ST4 headers and vice-versa. Samtec SS4 / ST4 0.40mm Ultra-Fine-Pitch Connectors operate in a -55°C to +125°C temperature range and are ideal for applications such as 5G networking, test connectivity, artificial intelligence (AI) and machine learning, broadcast videos, medical, and more.
