Important information to know about wiring, connectors and AMP CPC

• Series 1—Size 16 Contacts
  • Series 1 connectors permit the use of multiple combinations of signal and coaxial circuits in the same housing by accepting durable Multimate contacts. These pin and socket contacts include Type III+ and subminiature coaxial contacts,  Interchangeable in the same Multimate contact cavity.
  • Type III+ contacts (.062 [1.57] pin diameter) are capable of carrying a maximum of 13 amperes when crimped in wire.
  • Type III solder contacts and posted contacts for pc board applications  are also available. Many connector arrangements offer both standard and reverse sex contact loading, from 4
    thru 37 positions.
• Series 3—Power Contacts
  • Series 3 connectors accept Type XII power contacts which can carry up to 25 amps per contact. These contacts will accommodate a wire size range of 16 to 10 AWG [1.4 to 5 mm2]. Two connector sizes are available in both standard and reverse sex connector arrangements 3 and 7 positions.
• Series 4—Combination
  • Series 4 connectors accept Size 16 Multimate and Type XII power contacts, combining the signal and coaxial circuit capabilities of Series 1 connectors with the power circuit capabilities of Series 3 connectors. Available in two connector sizes  offering power mixing combinations totaling 16 and 22 positions.
• Connector Size—
  • In general, with more circuits in a connector, less current per contact can be carried.
• Wire Size—
  • Larger wire will carry more current since it has less internal resistance to current flow and generates less heat. The wire also conducts heat away from the connector.
• Current Load Distribution—
  • Spreading those lines with greater current loads throughout the connector, particularly around the outer perimeter, will enhance heat dissipation.
• Ambient Temperature—
  • With higher ambient temperatures, less current can be carried.

Current Rating Verification

Can a contact rated at 10 amps carry 10 amps?

Maybe yes, but probably not. The reason lies in the test conditions used to rate the contact. If these conditions do not adequately reflect the application conditions, the actual allowable current levels may be lower than specified levels. For example, many manufacturers, including Tyco Electronics, test a single contact in air. This gives an accurate measure of the basic current-carrying capacity of the contact. Use the contact alone in air and it can certainly carry 10 ampere. Use it in a multi-position connector surrounded by other current carrying contacts or in high ambient temperatures, and the contact should carry less current. Similarly, as the contact ages and stress relaxation, environmental cycling, and other degradation  factors take their toll, the contact’s current carrying capacity decreases. A prudent design must set current levels for such end-of design-life (EODL) conditions.  Practical current-carrying capacity is not an absolute, but an application-dependent  condition.
