Rectangular Connectors - Contacts

1. Pin Contacts

Pin contacts are cylindrical or square-shaped conductive elements that fit into corresponding socket contacts. They are often used in applications requiring high durability and reliability. Pin contacts are typically made from materials like brass or copper and are plated with metals such as gold or tin to enhance conductivity and prevent corrosion.

2. Socket Contacts

Socket contacts are designed to receive pin contacts, forming a secure connection. They often feature a spring mechanism to ensure a tight fit and maintain contact pressure. Socket contacts are used in applications where frequent mating and unmating are required, providing flexibility and ease of use.

3. Blade Contacts

Blade contacts are flat, elongated conductive elements that slide into corresponding receptacles. They are commonly used in power applications due to their ability to handle higher current loads. Blade contacts are often found in automotive and industrial settings where robust connections are necessary.

4. Spring Contacts

Spring contacts utilize a spring mechanism to maintain contact pressure and ensure a stable connection. They are ideal for applications requiring frequent disconnection and reconnection, such as in testing equipment or modular systems. Spring contacts offer excellent resilience and adaptability.

When selecting Rectangular Connectors - Contacts, several key parameters should be considered:

• Current and Voltage Ratings: Ensure the contacts can handle the required electrical load without overheating or failing.
• Material and Plating: Choose materials that offer good conductivity and corrosion resistance, such as gold or tin-plated copper.
• Contact Resistance: Lower resistance values indicate better conductivity and efficiency.
• Mechanical Durability: Consider the number of mating cycles the contacts can withstand without degradation.
• Environmental Factors: Evaluate the operating environment for factors like temperature, humidity, and exposure to chemicals, and select contacts with appropriate sealing and protection.

To assess product quality and reliability, review supplier certifications, customer reviews, and test reports. Installation requirements, such as space constraints and mounting options, should also be factored into the decision-making process.
