N2516-6002-RB is a 3M Four-Wall Header connector from the 2500 Series, designed as a low-profile, space-saving surface mount straight connector with 0.100" x 0.100" pitch. The connector features center slot polarization to prevent mis-insertions and reduce insertion time, with dual slot polarization for broader compatibility with competitive designs. It includes optional retainer clips for locking sockets in place and increasing connection reliability in vibration-prone environments, and optional high-temperature insulator suitable for "no lead" soldering operations. The connector is available in multiple pin configurations (6 to 64 positions) with plating options including 30µ" gold with 200µ" matte tin solder tails, and is commonly used in applications requiring reliable, stackable interconnections with ease of cleaning and reduced repair costs.
