  1. Order mark can be written in the form of fraction when it is required to order a whole set of connectors including plug and socket, that is, specify socket in numerator position while plug at denominator position with a slash sign between them.
  • Example: XC14F4Z1WP1/K1WP1 for a set of electroless nickel plated type 14 connectors with 4 contacts, Right angle cable clamp, N polarization and gold plating jacks and pins.
  1. One of the ends of XC-S-M series is sockets with jacks, specify the mating plug with pins in denominator position. Another end of XC-S-M series is sockets with pins, specify the mating plug with jacks right behind plug with pins, and add “.” between them for separation.
  2. When ordering accessories, please add “+” and follows the accessory code. Please refer to detailed requirements on XC & Derived Series Electrical Connector Accessory.
  3. The product will have A type crimp contacts in default configuration. If it is required to change for B type crimp pin or jacks, specify them(contact sizes or types) in parentheses behind order mark. E.g. XC30F30Z1D(φ1B).
