Latching relays are devices that maintain their position (on or off state) even after the control voltage is removed. They are distinguished by:
- Energy Efficiency: Relpol latching relays require only a pulse to change state, which allows for significant energy savings compared to traditional relays.
- Two Stable States: With two stable states (open/closed), these relays are ideal for applications that require maintaining a specific state for a long period.
- Robust Construction: High-quality manufacturing and the use of durable materials, such as AgNi, ensure long lifespan and reliability of the relays.
- Variety of Models: Relpol offers latching relays with different numbers of contacts, allowing the devices to be tailored to specific application needs.
Applications of Relpol Latching Relays
- Energy saving: R.N series latching relays have significantly lower energy consumption thanks to a mechanism that holds the contacts in a fixed position without the need for continuous power supply. Electricity is only consumed at the moment of switching the device's state (e.g. from ON to OFF or vice versa)
- Two steady states: After a power failure, Relpol bistable relays maintain the last contact position and resume operation in the same switching position when power is switched on again
- Robust Design: High-quality workmanship and the use of durable materials, such as AgNi, ensure long life and reliability of the relays.
Variety of Models: Relpol offers single- and double-coil bistable relays with different numbers of contacts, allowing the devices to be adapted to specific application needs.
