Features
●Common to all series
1. High Operating Temperature
DF59’s are rated at temperatures up to 105 ç.
●DF59
2. Swing Lock Structure (Wire-to-Board)
The DF59 features a “swing-lock” mechanism that employs
both a positive and friction lock. This helps to prevent
accidental unmating by severe wiring and mechanical stress.
3. Short-Circuit Pin
The Short-Circuit Pin allows the termination of an open circuit.
Typically used at the end of a series of connected circuit boards.
4. Multi Function Design
The DF59 has the ability to function as either a Board-to-
Wire or Board-to-Board System. The PCB mounted
receptacle is designed to mate with the W-to-B, B-to-B,
and Short Circuit Pin connectors. This multi function ability
allows versatility while keeping connectors to a minimum.
5. Contact Design
The terminal design features two-point contact to
ensure a highly reliable connection.
6. Common Applicator
Crimping can be performed using the applicator (AP105-
DF11-22S) for the existing series DF11-22S C F(A), by
replacing the die with the one for DF59 series.
* For crimping quality standards and crimping conditions,
crimping needs to be performed in accordance with the
specific conditions of DF59-22PCFA.
●Common to DF59/59S/59SN
7. Floating Structure (Board-to-Board)
The Board-to-Board connector can be used to connect two PCB
together in a co-planar arrangement and features a “Stress free
contact” that floats ± 0.5mm in the X, Y and Z dimensions.
8. Space Savings
The DF59 series offers high performance in a compact,
space saving design; featuring a 2mm pitch and coupled
with a mated height of only 2.48mm with AWG#22 cable.
The single position floating plugs DF59S and DF59SN
are specifically designed to save space, and can be
mounted in high density applications.
9. Robust locking structure on DF59M (W-to-B Connection)
The lock mechanism on compact DF59M provides
16N horizontal lock strength. (Fig.4)
10. Standardization of PCB layout
The DF59S/SN type is used on board-to-board connections,
and the DF59M type is intended for wire-to-board
connections. Although they have different receptacles, the
PCB mounting pattern can be used for these two types.
Different combinations of these connectors can be used in the
same system with a common PCB. This allows for
standardization of PCB. (Fig.5)
