1735482-5 is a 120-position PCB mount receptacle designed for vertical board-to-board connections in signal applications. It features a 0.8 mm centerline pitch with gold-plated mating contacts and tin-plated PCB termination areas, supporting surface mount assembly. The connector offers a free height design with stack heights ranging from 17 mm to 20 mm, operates within a temperature range of -40°C to +125°C, and is rated for 100 VAC operating voltage with a maximum contact current of 0.5 A. The stackable, parallel board-to-board configuration with polarization alignment makes it suitable for high-density interconnect applications in electronic assemblies requiring reliable signal transmission.
