1.Difference between Polarized and Non-polarized Relays
2.Features of polarized power relay
Latching type
Coil power consumption can be controlled, because ON or OFF state of relay contact can be held using pulse input (zero power consumption when there is no pulse drive).
High sensitivity
When compared under the same contact capacity, the polarized relays are more sensitive than non-polarized relays.
Superior vibration resistance
Superior NC (b contact) switching ability
Contact bouncing when resetting is controlled thanks to power of permanent magnet.
NC switching ability at same level as NO (a contact) is maintained.
