Protection fromshorts circuits
between adjacentcontacts

Fig.1Features
1. 5 Amps capacity
When used with 20 AWG wire, this connector has amaximum capacity of 5A.
(For rated current with other types of wires, please refer tothe table on the next page)

2. Secure lock mechanism
Outer locking mechanism prevents accidental unmating due
to external shocks or drops. (Fig.1)

3. Accurate board placement
Guide posts are used to help with board placement andprevent incorrect mating to the PCB.

4. Supports resin sealing
Accepts resin sealing up to 6.5mm without affecting theperformance.

5. Short circuit prevention
The housing protects each contact by enclosing them in a “box”
which also makes each contact independent of each other.
This design prevents short circuits between adjacent contacts.

6. Excellent contact retention
A retainer is available to increase contact/cable retention andto assure complete contact insertion. The retainer shouldalso be used when any mechanical stress cold be applied tothe cable.

7. Prevents solder cracking
To avoid solder crack, a glass-filled resin is used in theheader housing to decrease thermal shrinkage.

8. Easy mating operation
A clear tactile click is delivered upon the completion of themating process. This simplifies mating and increases work
efficiency, especially when operating in a noisy environment.

In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.

1. Insert the unmating tool and move or
disengage the contact lance. (as shownin the example on the left)

Contact lance

2. Make sure that the lance has moved
sufficiently enough to allow the terminatedwire to be removed easily.
Note : Lance strength may have decreased due to the repair work. It is recommended to use new crimp terminals instead of
reusing repaired crimp terminals. The case can be reused.

Caution
There are parts on the crimp contact that can cause injuries, please use caution when unmating
the contacts.

Operating Precautions

Aug.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.

These connectors can become damaged if excessive force is applied during extraction. If you experience difficultywhen unmating this connector, gently push it further into the housing and then operate the lock and release theconnector.
When performing a resin sealing, pay attention to the surface tension of the resin and fill accordingly.
Wire routing inside the device can cause added tension to be applied to the contacts. Use of a retainer will help
remedy the stress placed on the contact.
Prior to reusing a terminated wire, make sure that the contact’s lance is raised to the proper height.
There may be a slight variance in the color of the molding between production lots, this variance will not affect theperformance of the connector.
Black spots may appear on the mold resin but this does not affect the product quality.
Please refer to the documents "Cable assembly Procedure", "Crimp condition" and "Crimp quality standards" forthe cable assembly procedures.
Please refer to the "Nylon Connector Guide" for handling instructions.

Ratings
If the connector is rated at 3A, and the wire used with the connector only has a 1A capacity, the connection will beregarded as a 1A connection. Please make sure that you do not place too much current through this connector.
Even though the connector may be rated to take the current applied to it, currents are not always distributed equally
due to the differences in wiring path or contact resistance. Due to this precaution, the current may exceed theratings previously discussed. In these cases, use 1/3 of the noted rating as the maximum. Do not mate/unmate thisconnector when energized with a live current(Note 1) “Live” mating and unmating is defined as "to conduct the mating and unmating process while the system isconducting electricity"

Usage Under Harsh Environments
When using these connectors in a harsh environment such as one with repeated high and low temperatures, pleasecontact us for advice.
