Notes on Using Micro Coaxial Connectors

Safety precautions

Observe the following safety precautions to prevent accidents

and injuries.

1) The use of the connector outside of the specified rated current

and breakdown voltage ranges may cause abnormal heating,

smoke, and fire.

Never use the connector beyond the specified ranges of the

product.

2) In order to avoid accidents, make sure you have thoroughly

reviewed the specifications before use.

Consult us if you plan to use the product in a way not covered by

the specifications.

3) We are consistently striving to improve quality and reliability.

However, the fact remains that electrical components and

devices generally fail at a given statistical probability.

Furthermore, their durability varies depending on where and

how they are used. Please be sure to verify electrical

components and devices under actual conditions before use.

Continuously using them in a state of degraded performance

may cause deterioration in insulation performance, thus

resulting in abnormal heat generation, smoke generation, or fire.

To avoid that, we ask you to implement safe designs that include

redundancy, fire prevention, and malfunction prevention. Also,

please conduct periodic maintenance so that no accidents

resulting in injury or death, fire, or harm to society will be caused

as a result of product failure or service life.

About plug

The plug of this product is wired by soldering the 0.25 mm pitch

(CS)/0.4 mm pitch (CF) cable.

If you will be harnessing, carry it out based on the separately

attached “Plug Assembly Procedures”. Make sure to get familiar

with and observe all the precautions in the procedures.

Note: If you would like “Plug Assembly Procedures”, please

inquire at one of our sales offices.

• Caution regarding harness handling procedures.

To prevent the cable from being severed and to prevent damage

to the product, please handle carefully making sure not to apply

undue stress to the base of the cable after connecting it and

after mating the connector.

• Caution regarding harness design

To prevent the cable from being severed and to prevent damage

to the product, please place and secure the cable in a way that

prevents the base of the cable from becoming stressed.

About receptacle

• PC board design

Design the recommended foot pattern in order to secure the

mechanical strength in the soldered areas of the terminal.

• About (CF)

Use all the soldering terminals as GND for connecting GND

stably.

• Connector mounting

When mounting, if there is too much suction nozzle pressure,

the molded and metal parts might deform and break.

Please check beforehand.

• Soldering

1) Manual soldering.

• Since this connector is the low profile type the amount of solder

supplied should be closely monitored.

Too much solder during manual soldering may cause solder

creeping near the contacting part or a short circuit with the shell

(GND).

• Make sure that the soldering iron tip is heated within the

temperature and time limits indicated in the specifications.

• Flux from the solder wire may adhere to the contact surfaces

during soldering operations. After soldering, carefully check the

contact surfaces and clean off any flux before use.

• Be aware that a load applied to the connector terminals while

soldering may displace the contact.

• Thoroughly clean the iron tip.
