High Withstand-Voltage (3,000 V) Board-To-Cable Connector With Lock, MDF51 Series

High Withstand-Voltage (3,000 V) Board-To-Cable Connector With Lock, MDF51 Series

This is a board-to-cable connector for a circuit board with high voltage resistance that corresponds to 3,000 V and has a lock included. One-push connection operation is available for improved mating operability.

[Features]
• Connector mating in just one push: Through the utilization of an inertia lock, mating work can be performed easily and with certainty in just one push.
• This also prevents accidents resulting from partial mating.
• Improved workability through vertical mating: Vertical mating and horizontal cable pulling improve workability in the field. drawer allows improved working in the field.
• Also, the mating surface has a large guiding area to make insert operations easier to perform.
• Designed with high voltage in mind: In addition to the terminal pitch, the design accumulates a large side surface distance, retaining performance in a high voltage environment.
• Header connector uplift prevention: Through solder connections to a total of 4 areas, the header side housing is fixed firmly in place, preventing and uplift from occurring.
• Solder implementation for uplift prevention: As a solder implementation method for preventing uplift, a kink structure is included in the terminals (P = 12 mm products only).
• UL, C-UL, and TUV certified products: Those products have obtained safety standard qualifications as connectors (P = 12 mm products only).
