5177984-8 is a fine-pitch SMT stacking connector plug designed for parallel board-to-board interconnections in compact electronic assemblies. This 160-position connector features a 0.8mm free height (FH) configuration with dimensions of 63.20mm (A) × 69.80mm (B) × 68.20mm (C), and is available with either 8µ" or 30µ" gold plating on the contacts. The connector is rated for 500 VAC (1 minute) dielectric strength and operates reliably across a temperature range of -40°C to +85°C, including terminal temperature rise. These specifications make it suitable for high-density interconnect applications in telecommunications, computing, and industrial control systems where space constraints and reliable signal transmission are critical requirements.
