24v 30m Timer Relay

Adjustable Delay Timer Relay Details

1. A vacuum relay is a relay in which the contacts are placed in a glass or ceramic shell that is pumped into a high vacuum, and the vacuum is used as the arc extinguishing and insulating medium.

2. The vacuum has ideal insulation performance, which may reach a dielectric constant of 80,000V/mm in an ideal state. Since there is no oxygen in the vacuum, it will not be oxidized during use. In this way, the vacuum relay has a small value during use. And stable contact resistance.

3. Vacuum has good arc extinguishing performance. The arc in the vacuum is easy to spread, and it is not easy to cause wear to the contacts. Therefore, the vacuum relay has the characteristics of long life and can be equipped with a load switch.

In summary, the vacuum relay has the characteristics of high breakdown voltage, fast arc extinguishing, large breaking current, small size, lightweight and long life.

It is widely used in the fields of weak current control, such as cardiac pacemakers, nuclear magnetic resonance imaging, high-frequency antenna coupling devices, radar, and capacitor discharge.

4. High electrical resistance, high rated carrying current and conversion current, low contact resistance, stable operation, low noise, small inter-electrode distributed capacitance and inductance, small contact spacing, low excitation power, and fast-breaking speed, The contract is sealed, and it is not affected by the air pressure, moisture, dust or explosive gas in the surrounding environment, and is suitable for working in harsh environments.
