Frequently Asked Questions (FAQ)
What is the maximum current rating for these connectors?
These connectors are rated for 1A at 16V DC maximum. For higher current applications, consider using connectors specifically rated for your required current levels.
Are these connectors compatible with 2.5mm center pin plugs?
These connectors are designed for 2.1mm center pin plugs. While some 2.5mm plugs may fit, they may not provide optimal contact and could result in poor connections.
Can these connectors be used in outdoor applications?
While they have a wide operating temperature range (-30°C to +70°C), they are not specifically rated for outdoor or waterproof applications. For outdoor use, additional protection from moisture and environmental factors is recommended.
What is the purpose of the third pin/terminal?
The third terminal is typically used as a switch contact that opens when a plug is inserted. This can be used for applications like battery switching or power source selection.
Are these connectors RoHS compliant?
While specific compliance information should be verified with the manufacturer, most modern electronic components are designed to meet RoHS (Restriction of Hazardous Substances) standards.
