4.5 mm pitch, Horizontal Mating 2-Piece System Connectors
DF64 Series
■Features
1.Versatile Board-to-Board and Board-to-
Wire System
The DF64 Series connector system is a Board-to-
Board connector and Board-to-Wire that utilizes a
unique floating structure and a Board-to-Wire
connector that features an excellent locking system
2. Floating structure
The Board-to-Board floating structure delivers an
increased connection range together with a wide
effective mating length and width. The unique
stress-free contact structure was designed to
absorb movement and misalignment between serial
PCBs and ensure a continuous connection. (Please
refer to Figure 1)
Movement tolerance range for the X axis: ±0.5 mm
Movement tolerance range for the Y axis: MAX 2 mm
3. Reliable contact design
(B-to-B connection)
Our two-point contact structure provides a highly
reliable contact system. (Please refer to Figure 2)
4. Stress free side-locking system for
Board-to-Wire connections
The BTW side-locking structure provides a clear
tactile click to confirm completion of the mating
process and also allows for a visual check on the
side locks. The structure endures wiring stress and
prevents the wires from being pulled out of
alignment. (Please refer to Figure 3)
5. 350V voltage capacity
Its unique mating structure secures a creepage
distance of no less than 3.2 mm between the
contacts and produces a 350 V voltage capacity.
6. PCB layout simplification
The DF64 connector system shares one common
receptacle. This helps to simplify the PCB layout by
accepting the BTB header and the BTW cable plug.
7. Resistant to high heat
These connectors can operate in temperatures of
up to 105ç

6. Important Notes ■
When inserting the crimp contact into the crimp socket, do not insert it at a slanted
angle to maintain the reliability of its performance.
■ Please use caution when mating/unmating this connector if it has not been mounted
onto the PCB, doing so could deform or damage the contacts.
■ Do not pull on the wires of this connector as this may cause damage to the
connector.
■ During the hand soldering process, make sure to not apply too much fl ux. Doing so
may cause a solder wicking problem.
■ This product may experience some differences in color from one production lot to
another. This color difference does not infl uence the performance of the connector.
The characteristics and the specifications contained herein are for reference purpose. Please refer to the latest customer drawings prior to use.
