Omron switches to the high power relay sphere with G7EB
Omron Electronics Components Europe has launched a 100A device which features exceptionally low heat generation due to a low contact resistance. The G7EB is aimed at distribution power conditioning systems (PCS) as well as test equipment, such as semiconductor testers.
The trend for micro-generation from renewable sources has led to the popularity of the distribtion PCS. Andries de Bruin, senior European product marketing manager at Omron, said: “The challenge in these high current designs is controlling heat generation – a challenge which Omron directly addresses with this new design suitable for emergency cut off and similar high carry current applications.”
Omron G7EB can switch up to 100A at 800V AC. It has a low 5mOhm contact resistance, which is claimed to be an industry leading figure which greatly reduces heat generation within the component. This reduces the heat stress on the device and the surrounding circuit to improve reliability, but also minimises energy wastage. As a result, the G7EB experiences a temperature rise to about +40 degrees C with a 100A carry current, as opposed to +80 degrees C for competing designs, reports Omron.
PCS designs commonly feature three or more of this type of relay. At just 40.5 x 50.5 x 37mm, the G7EB helps reduce system size. The reduced requirement for heat sinks as a result of its cool operation saves additional space.
Omron is offering the G7EB with both industry standard and Omron proprietary pin layouts.
Omron Electronic Components Europe supplies electromechanical PCB relays, components such as micro switches, MOSFET relays, DIP switches, photomicrosensors and connectors. Omron’s technolgy portfolio includes MEMS-based pressure, flow and thermal measurement sensors, human face and gesture recognition modules, vibration and tilt sensors.
Omron Electronic Components Europe supports its customers in Western and Eastern Europe, Russia and the Commonwealth of Independent States (CIS) through eight regional offices, a network of local offices and partnerships with specialist, local, regional and global distributors.
Omron Electronic Components Europe is a subsidiary of the Omron Corporation, which produces electrical and electronic control equipment and component products.
