Introducing the ECC61DCSI, a high-performance board-to-board PCB connector designed for optimal connectivity in demanding environments. This female connector features two rows with a pitch of 2.54mm and can accommodate up to 122 positions, offering versatility in circuitry layout. Its threaded mount type and through-hole termination method ensure secure and reliable attachment to PCBs. Constructed with PBT and phosphor bronze materials, it guarantees durability and stability even in extreme operating temperatures ranging from -65 to 125°C. The contact plating of gold and termination plating of matte tin further enhance its conductivity and corrosion resistance. With a maximum voltage rating of 700 VAC and an amperage of 3A, this connector is suitable for various applications. Its hairpin contact type and straight orientation facilitate easy mating and un-mating processes. The compact design, with a connector height of 15.49mm and width of 9.4mm, makes it space-efficient on PCBs. Whether in aerospace, telecommunications, or industrial equipment, the ECC61DCSI ensures high reliability in signal transmission.
