A dust-proof cap to prevent contamination from foreign bodies and protect the connected portion
● It is mounted to the panel mount receptacle or the relay adapter and prevents dust or foreign matter from entering into the fitting portion when the connector is not used.
● It prevents accidents caused by exposed live parts when not connected.
· Not a waterproof structure.
· If you want to use it with the cable clamp NMS3057 fitted to the relay receptacle NMS3101B, the chain terminal cannot be fitted to the cable clamp with the shell size of 22 or less.

Contact Arrangement Table (by number of cores) View from the male (pin) connector coupling surface.
Arrangement No.
The left side is the shell size of the entire connector. The right side is the arrangement number of the contact. Together these compose the Arrangement Number.
Core Number Composition
The right side is the size of 1 contact. The left side is the number of contacts.
When ordering parts, please determine the voltage, current, number of cores, size, etc. from the table below, depending on the working environment.
Note 1: Rated current is the value for single contacts when incorporated in the connector. Please note that the rated current does not change according to the voltage.
Note 2: Rather than the size of the contact or shell, rated voltage changes by arrangement of contacts.
Note 3: In some items, rated voltage diverges by each contact even when within the same connector.
Note 4: Properties will vary depending on the test category.

Current Capacity of Entire Connector
Rated current value per 1 contact varies depending on the size of the contact, but the current capacity that can flow safely through the connector varies depending on the total number of cores. The calculation method for 14-core or less and 15-core or more is different, so they are described separately.
(1) For 14-core or less
The rated current value per 1 contact at the time of connector incorporation is multiplied by the number of cores and then multiplied by the reduction factor in the figure below. The result is the allowable current of the entire connector.
■ Current Reduction Factor Table by Number of Cores
| Total Number of Cores | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Reduction Factor (%) | 1 | 0.943 | 0.886 | 0.829 | 0.771 | 0.714 | 0.657 | 0.6 | 0.543 | 0.486 | 0.429 | 0.371 | 0.314 | 0.257 |
Example 1: For connectors with all contacts of the same size
Rated Current Value per 1 Contact x Number of Cores x Reduction Factor = Allowable Current of Entire Connector
13 A x 2 cores x 0.943 = 24.518 A
(When Arrangement Number is 12S-3)
Therefore, 24.518 A can be used for the entire connector.
Rated Current Value per 1 Contact x Number of Cores x Reduction Factor = Allowable Current of Entire Connector
13 A x 2 cores x 0.943 = 24.518 A
(When Arrangement Number is 12S-3)
Therefore, 24.518 A can be used for the entire connector.
Example 2: For connectors with contacts of different sizes
(Contact A Rated Current x Contact A Number of Cores + Contact B Rated Current x Contact B Number of Cores) x Reduction Factor (for the total number of cores) = Allowable Current of Entire Connector
(23 A x 2 cores + 13 A x 7 cores) x 0.543 = 74.391 A
(When Arrangement Number is 20-16)
Therefore, 74.391 A can be used for the entire connector.
(Contact A Rated Current x Contact A Number of Cores + Contact B Rated Current x Contact B Number of Cores) x Reduction Factor (for the total number of cores) = Allowable Current of Entire Connector
(23 A x 2 cores + 13 A x 7 cores) x 0.543 = 74.391 A
(When Arrangement Number is 20-16)
Therefore, 74.391 A can be used for the entire connector.
(2) 15-core or more
The rated current value per 1 contact is multiplied by the number of cores and 20% of that value is the allowable current of the entire connector.
Example 1: For connectors with all contacts of the same size
Rated Current Value x Number of Cores x 20% = Allowable Current of Entire Connector
13 A x 17 cores x 0.2 = 44.2 A
(When Arrangement Number is 20-29)
Therefore, 44.2 A can be used for the entire connector.
Rated Current Value x Number of Cores x 20% = Allowable Current of Entire Connector
13 A x 17 cores x 0.2 = 44.2 A
(When Arrangement Number is 20-29)
Therefore, 44.2 A can be used for the entire connector.
Example 2: For connectors with contacts of different sizes
(Contact A Rated Current x Contact A Number of Cores + Contact B Rated Current x Contact B Number of Cores) x 20% = Allowable Current of Entire Connector
(23 A x 4 cores + 13 A x 18 cores) x 0.2 = 65.2 A
(When Arrangement Number is 28-11)
Therefore, 65.2 A can be used for the entire connector.
(Contact A Rated Current x Contact A Number of Cores + Contact B Rated Current x Contact B Number of Cores) x 20% = Allowable Current of Entire Connector
(23 A x 4 cores + 13 A x 18 cores) x 0.2 = 65.2 A
(When Arrangement Number is 28-11)
Therefore, 65.2 A can be used for the entire connector.
