The 0.80mm pitch dual-row configuration with gold-plated copper alloy contacts (0.38\u00b5m gold) ensures reliable signal integrity for SAS (Serial Attached SCSI) and PCI Express differential signal pairs. The right-angle surface-mount design includes an SMT metal shell for EMI shielding and grounding, while the board guide feature facilitates precise PCB alignment during mating. The dual-key design prevents incorrect connector orientation, ensuring reliable assembly in high-density server backplane applications.","working_principle":"1. Differential Signal Pairs: The 36 contacts are organized as differential signal pairs for high-speed SAS\/PCIe transmission. The 0.80mm pitch and controlled impedance design minimize crosstalk and signal reflection, supporting data rates up to 12Gbps and beyond.\n2. Mating Sequence: The connector features a three-stage mating sequence (first mate, second mate, third mate) with different pad configurations. Power\/ground contacts mate first (pre-charge), followed by signal contacts, ensuring hot-plug safety.\n3. EMI Shielding: The SMT metal shell provides electromagnetic shielding around the connector body. When mated, the receptacle shell contacts the plug shell, creating a continuous Faraday cage that contains EMI and provides ground return path.\n4. Board Guide: Integrated guide features on the connector body align with PCB cutouts, ensuring the connector is placed accurately during pick-and-place assembly and providing mechanical support during mating.","pin_description":"
