Pressure Welding Bar Connector (JC15) 1.5mm Pitch Description In general, pressure welding bar connectors are designed to provide a reliable and strong electrical connection between two or more conductors. These connectors typically feature a high-pressure welding process that fuses the conductors together, creating a permanent and low-resistance connection. Product Display This low-profile, board-in connector, with a mounting height of only 4.25mm and a thickness of 2.4mm, is soldered directly onto PC boards.
