Operating Precautions

Ratings

These connectors can become damaged if excessive force is applied during extraction. If you experience difficulty

when unmating this connector, gently push it further into the housing and then operate the lock and release the

connector.

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 the

performance of the connector.

Please refer to the documents "Cable assembly Procedure", "Crimp condition" and "Crimp quality standards" for

the cable assembly procedures.

Please refer to the "Nylon Connector Guide" for handling instructions.

If the connector is rated at 3A, and the wire used with the connector only has a 1A capacity, the connection will be

regarded 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 the

ratings previously discussed. In these cases, use 1/3 of the noted rating as the maximum. Do not mate/unmate this

connector 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 is

conducting electricity"

Usage Under Harsh Environments

When using these connectors in a harsh environment such as one with repeated high and low temperatures, please

contact us for advice.
