Notes:

• When indicating an electrical connector, the model number is in fractional form. The receptacle mark writing numerator, the plug mark writing denominator (can only indicate the plating and structure of the plug housing) are separated by diagonal lines, see the model mark example.
• The plug and receptacle models are directly marked on the product, and the electrical connector model is available for the user to order and the company’s production, operation and management.
• The optional accessories can be ordered separately. See the post for details.
