sUsage Precautions
1. Plugs
(1) Insertion and removal
of connectors
Be sure to check the polarity mark before mating the connectors. Attempting to forcefully mate the
connectors in reverse will ruin or scrape the connectors.
(3) Precautions
These connectors are not suited for external interfaces. Note that insertion or removal using excessive
twist will result in damage.
(2) Permissible load
placed on the cable
after the connectors
are mated
1) After the connectors are mated, do not apply a load to the cable in excess of the value indicated in the
diagram below.
qComplete lock type
MRF03-6P-0.8D
MRF03-6P-1.27
qPush-on lock type
Pulling the cable of the push-on lock type results in the disconnection of the connector.
MRF03-6P-0.8D
MRF03-6P-1.27

9.8N or less
49N or less

9.8N or less
Not permitted
2. Receptacles and Plug Receptacles
(1) Recommended
temperature profile
(Reference)
1) Permitted up to two times with the same conditions; however, there must be a period at room
temperature between the first and second times.
2) The temperature indicates the board surface temperature at the connector lead portion.
3) Reflow soldering should be performed at a peak temperature of 240C or less at the surface of the
printed circuit board.
4) The temperature profile will change depending on such factors as the size of the board, the solder used,
and the solder thickness.
(3) Precautions
1) A special tray is used in the packaging of these connectors. Application of excessive force to the
contacts will result in misshaped contacts and the soldering quality will be lost at the time of reflow
soldering. For these reasons, dropping or rough handling of the product should be avoided.
2) Be careful not to misshape the contacts or fittings if the connectors are inserted or disengaged before
soldering.
(2) Recommended hand
