1565357-9 is a 0.5mm pitch fine mate receptacle connector designed for parallel board-to-board stacking applications. This 20-position connector features a 4.5mm stacking height and is constructed with a 6T nylon high heat resistant resin housing, phosphor bronze contacts plated with gold over nickel, and a copper alloy tail plate plated with tin. The connector is optimized for surface mount technology (SMT) placement on printed circuit boards with a minimum thickness of 0.6mm, and is supplied in tape and reel packaging conforming to EIAJ standards. It is widely used in miniaturized consumer electronics applications such as cellular phones, pagers, notebook computers, and camcorders where space constraints and automatic assembly are critical requirements.
