Featured Products
Omron Electronics G9KA-E Power PCB Relays offer ultra-low contact resistance of ≤0.2mΩ, minimizing heat generation on the PCB. These relays provide greater capacity than the standard G9KA, handling up to 1000VAC and 300A. Their optimized terminal design improves heat dissipation, maintaining low temperatures. The double brake and twin contact structure reduces contact resistance, while the plunger-style relay design enhances durability with lower power consumption. Omron’s G9KA-E Power PCB Relays are ideal for industrial inverters, high-voltage systems, EV charging stations, and uninterruptible power supplies (UPS).
