SS5/ST5 0.50mm Ultra-Fine-Pitch Connectors

Samtec SS5 / ST5 0.50mm Ultra-Fine-Pitch Connectors provide up to 56Gbps PAM4 performance and are designed for board-to-board connections where space is at a premium. The slim body connectors are manufactured on an ultra-fine 0.50mm pitch and feature up to 160 I/Os with mated stack heights as low as 4mm. These Razor Beam™ LP family sockets and headers are engineered to save space on the X, Y, and Z axes. Samtec SS5 / ST5 0.50mm Ultra-Fine-Pitch Connectors are available in a straight or vertical configuration, and the SS5 sockets are designed to mate with the ST5 headers and vice-versa. Both series operate in a -55°C to +125°C temperature range. Ideal applications include 5G networking, artificial intelligence (AI) and machine learning, military / aerospace, medical, automotive, and more.
