Description:
Latching relay is a new type of relay which uses magnetic principle to control circuit’s on and off. Its normally open and closed state are provided completely by permanent magnet steel’ working and completed the conversion of on-off state base on the triggering of a certain width pulse signal.
Product Properties:
1.Small volume, big switching power and low consumption
2.Coil instantaneous pulse driving and without fever
3.Stable permanent magnet force and save energy
4.High contact pressure, low contact resistance, working stable and reliable, anti-vibration and anti-shock.
5.Use manganin welding, low material temperature coefficient and compact structure.
Latching relay advantages:
(1)only need pulse excitation and can be single or double coils working
(2)small volume and PCB installation
(3)low power consumption and strong load capacity
(4)security, reliable and long working life
The effect of magnetic latching relay:
1.Expand control range. For example, when Multi- contact relay control signal reaches a certain value, it can simultaneously switch, disconnect and connect multiplex circuits according to the different forms of contact groups.
2.Enlarge. Such as sensitive relay, intermediate relay etc, it can control big power circuit with a very small control signal.
3.Integrated Signal. For example, when many control signals input multi-winding relay per required form, after comparing and integrating it can reach the intended control effect.
4.Automatic, remote control, monitor. For example, other relays and relay of automatic device can make up programs to control circuit, then reaching automatic operating.
Operating system:
Magnetic Latching Relay is a kind of high-power relay, of which the contact
condition is maintained by the magnetic force from permanent magnet. When the load
need to be open or closed, positive and negative dc impulse voltage will drive
the coil,so that relay can complete the state transition between opening and closing
instantly. And then, the coil doesn’t need electricity any more, only by the magnetic
force of permanent magnet, its condition can be maintained.
