1. High Operating Temperature
●DF59
DF59’s are rated at temperatures up to 105 ç.
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.
2. Swing Lock Structure (Wire-to-Board)
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.
Fig.1
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.
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)
Note : Each stencil mask is necessary
Standardization of PCB pattern
DF59S/SN type and DF59M type can be used in the
same system by using a common PCB.

No melting of resin which affect the performance.
Note 1 :
Including temperature rise caused by current flow.
Note 2 :
The term “storage” refers to products stored for long period of time prior to mounting and use.
Operating temperature and humidity range covers connectors after installation, storage, shipment or during transportation.
Note 3 : The rated voltage is the applied voltage when connectors are mounted parallel to each other on the PCB with a distance of 1.6mm
or more between them. Hirose recommends his mounting distance.
This mounting distance is required in order to prevent creepage between the printed wiring to maintain an effective voltage of
300V, according to IEC 60664 and JIS C 60664 standards.
