The 3M™ Ultra Hard Metric (UHM) Press-Fit Socket is a 2mm connector with 55, 95, 110, and 125 signal contacts, 5+2 rows, and a right angle design. It features data rates of 7+ Gbps when mated to standard IEC 61076-4-101 headers, low crosstalk at high frequencies, 50/100Ω impedance, modular/scalable format, 63 mated lines per linear inch, and a dual beam contact construction for high reliability. It can be stacked end-to-end with other 3M™ CP2, HM, UHM, and HSHM sockets and mates with 3M™ CP2, HM, UHM, HSHM headers, and cPCI™ type headers.
The 3M Ultra Hard Metric (UHM) press‑fit socket series provides high‑speed interconnects for 2 mm B‑type configurations with 55, 95, 110 and 125 signal contacts arranged in 5+2 rows and a right‑angle layout. The design supports 7+ Gbps data rates, low crosstalk, and 50 Ω single‑ended or 100 Ω differential impedance, making it suitable for high‑frequency applications.
The datasheet includes mechanical specifications such as normal and separation forces, electrical ratings like 1 A at 70 °C, and environmental limits from –55 °C to 125 °C. Ordering information, hole‑pattern recommendations, and extensive RoHS/China RoHS compliance details are also provided.
