3.5‑mm Pitch 2-Row Connector For Small Internal Power Supplies, MDF6 Series
Caution
Product Description
Connector for board-to-cable connection with 3.5mm pitch. Although compact in size, this connector supports 7 maximum amperes, and its inner-lock construction provides a highly reliable connection, ideal for internal power supplies.
[Features]
· Compact type with 3.5mm pitch: A small-size, space-saving power supply connector, with pitch between adjacent contacts set at 3.5 mm, and arranged in a double-row pattern with 5 mm between opposing sides.
· 7A current rating ensured: Despite the compact size of the power supply, 7A current rating is ensured with use of AWG #16 wires (UL/CSA rating is 6A). Box-style header: Twist-resistant due to its box-style construction, enabling complete prevention of insertion errors.
· Equipped with inner-type full lock: An inner-type full lock with a locking section that is not exposed to the outside ensures secure engagement for a high level of safety.
In-stock items are made-to-order, so returns and cancellations are not possible. Thank you for your understanding.
