    Product Details

    Features and Advantages

    • 1
      The J29A connector's high density is achieved through precise engineering: it utilizes a stranded conductor pin design for flexibility and reliable contact, with anode space (contact-to-contact distance) of 1.91mm and an array pitch of 1.65mm.
    • 2
      This configuration allows for an exceptionally high number of contacts in a very small area, which is its primary advantage.
    • 3
      The series accommodates a wire core cross-sectional area range of 0.15mm² to 0.3mm², suitable for fine-gauge wiring.
    • 4
      The most prominent external feature is its exceptionally small outer dimension, a direct result of the high-density layout.
