Features

High housing strength and stable shielding performance

Product with aluminum alloy housing, featuring high strength and stable shielding performance compared with those of plastic housing connector.

Multi-key error proofing function

Developed five key positions (A/B/C/D/E), with multi-key error proofing function, meeting the requirements for connection between multiple pieces of electrical equipment.

High wiring efficiency

The integrated bellows fixing technology is adopted. The process of using baking heat shrinkable tubes or wrapping tape during wiring harness operation is eliminated, resulting in high wiring efficiency.

Easy plugged/unplugged secondary lock

Designed with the secondary locking function of connector, convenient for plugging and unplugging, and more reliable in connection.
