PCB Power Relays
PCB Power Relay Definition
Relays mainly used for more than 3A load switch, and equipped in household appliances, such as refrigerators, washing machines, and AV device, as well as various FA equipment, industrial equipment, and household equipment.
PCB Power Relay Features
Power relays for printed circuit boards offer superior performance in high-capacity load switching in the power supply system owing to its material that can resist to contact arc and single contact structure (see figure). These power relays also retain excellent performance in contact volume and contact pressure.
In addition, these power relays comply with various safety standards. The products line-up includes relays that have enhanced insulation distance between coil contacts

PCB Power Relay Types
Omron's power relays for printed circuit boards contribute to high functionality and safety of devices with wide variety of current capacities (3A-30A), contact structures, protective structures, and coil specifications.
PCB Power Relay Diagram
The power relays for the board have suitable structures according to applications, and are generally composed of a plurality of components as shown in the following figure. This figure shows an example of a hinged relay.
