Features –––––––––––––––––––––––––––––––––––––––––––––––––––––––––
• The mating section of the contact has a twin-contact style
construction with uniform elasticity to ensure a reliable contact
even when repeatedly mated and unmated.
• A wide variety of grounding adapters are available so that the
receptacle can be grounded to the circuitry of a printed circuit
board to prevent electromagnetic interference.
* Compliant with RoHS.
* Refer to "General Instruction and Notice when using
Terminals and Connectors" at the end of this catalog.
* Contact JST for details.
