The SDN connector is a 3.96mm pitch
board-in crimp style connector capable of
connecting a wide variety of circuits
including signal and power supply circuits.
The connector features a slim, low-profile
design. In addition, it has an exclusive
lance construction to reduce insertion
force, thus substantially improving the
working efficiency in mounting the contact.
• Slim, low-profile design
• Easy and secure contact mounting
• Improved solderability
• Polarizing boss
Note: 1. Tolerances are non-cumulative:
±
0.05mm for all centers. For connectors with 5 or more circuits the hole dimensions will differ from the above values.
Contact JST for details.
2. Hole dimensions differ according to the kind of PC board and piercing method. The dimensions above should serve as a guideline.
