2.5mm Pitch Connector for Discrete Wire Connection (Product Compliant with UL/CSA Standard)
DF1B Series
sFeatures
1. New Insulation Displacement and Crimping Ideas
This connector is a new type to insert the ID contacts in the case. Using this
method, the following merits can be gained.
1
By using the ID contact and crimping contact together, different current
capacity cables can be mixed in one case.
2
After connection, the contact can be replaced in excellent maintainability.
3
Because the insulation displacement area is protected by the case, high
reliability can be assured.
4
Since the insulation displacement process can be performed only by
replacing the applicator of the existing crimping machine, no expensive
machine for insulation displacement is required.
Cables with different current capacities
can be mixed in one case

Potting status
2. Potting Header Available
The high profile header is also available, corresponding to the board potting
process (sealed with resin) as waterproof measures.
3. Broad Variations
The single row and double row contacts are aligned for "Board to Cable" and
"In-line" series, respectively, while standard tin and gold plating products are
available.
(Refer to the applicable combination pattern on next page.)
