1- High Electrical Conductivity: Silver is one of the most conductive metals, making it an excellent choice for electrical contacts. This high conductivity ensures minimal resistance and energy loss across the contacts, which is crucial for efficient relay operation.
2- Low Contact Resistance: Silver contacts tend to have low contact resistance, meaning that they create minimal obstruction to the flow of electrical current. Low contact resistance helps to maintain a stable and reliable electrical connection, reducing the likelihood of voltage drops and heat generation across the contacts.
3- Good Oxidation Resistance: Silver exhibits good resistance to oxidation, especially in comparison to other metals like copper. This property helps prevent the formation of insulating oxide layers on the contact surfaces, which could otherwise impede electrical conduction and lead to contact failure over time.
4- Reliability: Silver contacts are known for their reliability and long service life, even under demanding operating conditions. They can withstand numerous switching cycles without significant degradation in performance, making them suitable for use in various industrial and commercial applications.
5- Compatibility with Low-Level Signals: Silver contacts are often preferred for relays that handle low-level signals or low-current applications, where maintaining signal integrity and minimizing signal distortion are critical.
Overall, the use of silver contacts in T90 relays helps ensure optimal performance, reliability, and longevity in diverse electrical switching applications.
