1. Contact Pitch

Narrower external width and length

1mm contact pitch allows reliable solder and cabletermination.

2. Reliable electrical connection wipe
Effective electrical connection is assured with a 1mm
wipe of mating contacts.

3. Narrower external width and length
Redesigned metal fittings decreased the overall lengthof the board- mount receptacle and permit end-to-end
mounting of several connectors.

4. Automatic equipment board placement
Straight type pin headers are supplied with a 5.4mm ×
4.6mm flat platform to allow vacuum pick-up andplacement on the board.

5. Product variations

Metal fitting(1) Available with 10, 20, 30, 40, and 50 contacts.
(2) Pin headers are available in two types : with orwithout board positioning bosses.
(3) Depending on specific application pin headers canbe ordered in straight or right angle types.

■Applications
Notebook PC, small office automation equipment, small
consumer devices, portable devices.
Any application requiring low profile reliable board-to-cableconnection with a 28 AWG, 30 AWG, 32 AWG conductors.

■ToolsWhen crimping work is applied to our contacts, the tool designated by Hirose should be used.
Crimping work by using tools other than as designated must not be done because it may result in contact failure,
disconnection of cable, etc.
*The operating instructions manual is available for the crimping machine and the applicator.
Be sure to carefully read the operating instructions manual befor implementing the work.

■Applicable electric wires
Check that the electric wire to be used is in the range of application.
If you intend to use an electric wire other than the recommended one, ask our sales personnel.
[Precautions]・Electric wires that are applicable for crimping connectors shall, principally, be the tin-plated stranded softcopper wire.
・Crimping of electric wires wherein single wires, polyester yarns, etc., exist and crimping of tin-coated wires should
be avoided.
・Avoid crimping two electric wires together.
・The setting values of crimp height (Note 1) may vary between tin-plated and gold-plated terminals even if thesame electric wires are used.
・The setting values of crimp height (Note 1) may vary depending on the difference in the core wire configurationeven if the computed cross-sectional area is the same.
Note 1 : The crimp height is an important item that determines crimping quality. We execute crimping tests foreach electric wire to ensure the optimal value for the crimp height with high precision, thereby ensuring
optimal setup values.

5. Cleaning Conditions

Refer to "Wire-to-Board Connector Use Handbook"

6. Wiring Termination Conditions

Refer to "Wire-to-Board Connector Use Handbook"
Crimp contacts should be handled with care as not to cause any deformation or damage
affecting the performance or termination.

7. Cautions

Excessive twisting and pulling on wires during mating/un-mating should be avoided as it
may cause damage to connectors.
Black spots may appear on the mold resin but this does not affect the product quality.

8. Precautions

Please refer to the following documents.
■ Crimp Quality Standard (ETAD-H0929-00)■ Cable Assembly Procedure (ETAD-H0930-00)■ Mating/Unmating Operation Instruction Manual (ETAD-H0997-00)■ User Guide for Wire-to-Board Connector
