The N2520-6002-RB is a 20-pin, straight through-hole, four-wall header from the 3M 2500 series, designed for robust board-to-board connections. It is constructed with a high-temperature black PCT insulator, making it suitable for "no lead" soldering operations and "paste in hole" reflow techniques up to 260°C. The copper alloy contacts feature 30µ” gold plating in the wiping area and 200µ” matte tin on the solder tails, which are configured for standard .062-inch thick boards. This model includes center slot polarization to prevent mis-insertions and operates over a temperature range of -55°C to +105°C, making it ideal for a wide range of industrial and electronic applications where reliability is critical.
