ERM8-040-01-S-D-EM2-DS-TR

The ERM8-040-01-S-D-EM2-DS-TR from Samtec Inc. is a high-performance Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) engineered for demanding board-to-board applications. This connector delivers exceptional signal integrity and power distribution capabilities, making it ideal for 5G base stations and high-speed computing systems. With its advanced contact technology and robust construction, it ensures reliable performance in harsh operating environments.Featuring a Differential Pair Array, Male configuration, this solution provides optimal mating stability while minimizing insertion loss. When compared to conventional designs, the patented contact geometry reduces crosstalk by up to 30%.Available in 80 contact arrangements, the connector supports flexible power delivery configurations. System designers can choose between signal-dominant or power-optimized layouts based on application requirements.The ultra-fine 0.031" (0.80mm) spacing enables high-density PCB layouts without compromising signal integrity. This precision spacing is particularly beneficial for miniaturized RF modules and compact embedded systems.With 2 rows configuration, the connector achieves balanced impedance characteristics across all channels. The symmetrical layout minimizes skew variation for high-speed differential pairs.Designed for Board Edge, Straddle Mount installation, this connector simplifies assembly processes while maintaining mechanical robustness. The mounting system has been validated for automated pick-and-place operations.Utilizing Gold plating technology, the contacts maintain low contact resistance over 10,000 mating cycles. This finish selection provides optimal performance in humid environments.The precisely controlled 30.0µin (0.76µm) ensures consistent electrical performance while providing adequate wear resistance. This thickness specification meets MIL-STD-202H for military applications.
