1. Figure shows the receptacle contact arrangement as viewed from the interface mating side (plug's socket insert side).
2. Current capacities are shown in a value per contact.
3. The contact numbers with a mark " ◎ " have contacts that are grounded to the outer shell, except for receptacles that are size
24-10.
4. For the receptacles that are size 24-10, the ground contact (contact No.: G) does not ground with the outer shell. Please use
these connectors after grounding the outer shell of the connector with the corresponding contact No.
5. The degree of pollution and conducting voltage categories refer to the environmental condition in which a DIN VDE0110
(insulation coordination for the electric appliances in a constant voltage facility) electric appliance is used, and to the class of
over voltage in the electric appliance.
6. Performance values for other than those shown above are the same as those of the general H/MS series.

Usage Recommendations
(1) The power to the circuit should always be off before mating/unmating a connector.
(2) Always use a female connector for the power side of the circuit; this will prevent the likelihood of electric shocks.
(3) Be sure to fully tighten the lock mechanism of the connectors.
(4) Connector performance features such as cable clamping force, cable rotation force, or waterproof performance may differ
depending on the cable construction. Please make sure all specifications are met before assembly.
(5) This product uses silver-plated contacts. Please be aware that silver easily reacts to sulfur gases, causing discoloration or
degradation when exposed to certain environmental conditions as shown below. These conditions include areas with:
• A large amount of dust and dirt
• High density of sulfur dioxide gas, hydrogen sulfide gas, nitrogen dioxide gas, or other gas (Emission gases from vehicles
and factories, etc.)
• Highly fluctuating temperatures, such as close to a heating apparatus
In addition, it is recommended to store the products in their original packaging or similar state in order to prevent
discoloration.
• Temperature: -10 to +60°C, relative humidity: 80% or lower (An environment where temperature and relative humidity are
constant and there is less temperature difference is recommended.)
• Please use the products within six months after delivery.
(For the products in which the storage period is expired, please confirm the ease of soldering for your application
beforehand.)

(6) Please confirm the following information when routing the cable after assembling the crimp contacts into the crimp type
connector.
①Do not apply a force of 20N or greater to the cable. Applying a force of 20N or more may result in breakage of the insulator
inside the connector or contact failure resulting from contact disconnect.
②When routing, bend the cables at a curve in order to prevent a force to the crimped portion.
If the cable is bent directly at the edge of the connector and routed, the cables on the outer side will be pulled more than
those on the inner side.
This may result in breakage of the insulator inside the connector or contact failure resulting from contact disconnect.
①Securing force of crimp contact
