Common Specifications
Applied Wire Size and Contact Size
Applicable wire coating strip length is about 1 to 3 mm plus the soldering hole length (L dimension) of the contact. In addition, the L dimension and D dimension are the same for the male connector (pin) and female connector (socket). Also, confirm whether the cable will fit into the internal diameter of the cable clamp when selecting cables.| Contact | Conforming wire size | ||||

Contact arrangement table (in order of core number), a view from the coupling surface of the male (pin) connector.
Arrangement No.
The shell size of the entire connector is at left. The arrangement number of its contacts is at right. Together they comprise the Arrangement No.
Configuration of Number of Cores
The size per contact is shown on the right. The number of contacts is shown on the left.
Determine the model according to the operating environment, such as voltage, current, number of cores, or size, when ordering parts.
*1: The rated current is the value of the contact as a single unit when each contact is embedded in a connector. Note that the rated current will not change depending on voltage.
*2: The rated voltage will change depending on contact arrangement rather than on the size of contacts or shells.
*3 The rated voltage may be different with each contact even in the same connector.
*4 Characteristics will change depending on test classification.

Current Capacity Applicable to Entire Connector
The rated current value per contact will vary depending on contact size, but the current capacity which can be applied to the entire connector will vary depending on the total number of cores. Since calculation differs for 14 cores or less and for 15 cores or more, they will be explained separately.
(1) For 14 Cores or Less
The current capacity applicable to the whole connector is calculated by multiplying the rated current value per contact when embedded by the number of cores, and then multiplying it with the reduction ratio in the following figure.
■ Current Reduction Ratio by Number of Cores Table
| Total Number of Cores | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Reduction Ratio (%) | 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 the same contact size
Rated current per contact x number of cores x reduction ratio = entire connector allowable current
13 A x 2 cores x 0.943 = 24.518 A
(For Arrangement No. 12S-3)
Therefore, 24.518 A can be applied to the whole connector.
Rated current per contact x number of cores x reduction ratio = entire connector allowable current
13 A x 2 cores x 0.943 = 24.518 A
(For Arrangement No. 12S-3)
Therefore, 24.518 A can be applied to the whole connector.
Example 2: For connectors with different contact sizes
(A contact rated current x number of A contact cores + B contact rated current x number of B contact cores) x reduction ratio (for total number of cores) = entire connector allowable current
(23 A x 2 cores + 13 A x 7 cores) x 0.543 = 74.391 A
(For Arrangement No. 20-16)
Therefore, 74.391 A can be applied to the whole connector.
(A contact rated current x number of A contact cores + B contact rated current x number of B contact cores) x reduction ratio (for total number of cores) = entire connector allowable current
(23 A x 2 cores + 13 A x 7 cores) x 0.543 = 74.391 A
(For Arrangement No. 20-16)
Therefore, 74.391 A can be applied to the whole connector.
(2) For 15 Cores or More
The current capacity applicable to the entire connector is calculated by multiplying the rated current value per contact by the number of cores and then multiplying it by 20%.
Example 1: For connectors with the same contact size
Contact rated current x number of cores x 20% = entire connector allowable current
13 A x 17 cores x 0.2 = 44.2 A
(For Arrangement No. 20-29)
Therefore, 44.2 A can be applied to the whole connector.
Contact rated current x number of cores x 20% = entire connector allowable current
13 A x 17 cores x 0.2 = 44.2 A
(For Arrangement No. 20-29)
Therefore, 44.2 A can be applied to the whole connector.
Example 2: For connectors with different contact sizes
(A contact rated current x number of A contact cores + B contact rated current x number of B contact cores) x 20% = entire connector allowable current
(23 A x 4 cores + 13 A x 18 cores) x 0.2 = 65.2 A
(For Arrangement No. 28-11)
Therefore, 65.2 A can be applied to the whole connector.
(A contact rated current x number of A contact cores + B contact rated current x number of B contact cores) x 20% = entire connector allowable current
(23 A x 4 cores + 13 A x 18 cores) x 0.2 = 65.2 A
(For Arrangement No. 28-11)
Therefore, 65.2 A can be applied to the whole connector.
