R005 100A/120A 250VAC Latching Relay
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.
