2.5mm Pitch Connector for Discrete Wire Connection
DF1 Series
■Features
1. Board Mounting Height (Crimping Type)
10mm
2.5mm pitch connector achieves the low profile.
2. Insulation Displacement Area Protected by Protector (ID Type)
The connector is structured to protect the insulation displacement connection area by the protector. Therefore, the connector
has a strong tensile strength against the cable and prevents dusts.
3. Easy Connection by Easy Tool (ID Type)
No expensive insulation displacement machine is needed. The connection can be established only by mating the cable into the protector
and fastening it with the ID tool
.
4. Intermediate Connection Possible (ID Type)
For intermediate connection, the connector allows signal extraction during cabling.
