Three new DC power relay products focusing on "high reliability" and "miniaturization" required for moving bodies
Power relays are used to supply 12 V and 24 V power to robots mounted on top of moving vehicles, and for opening and closing small 12 V and 24 V motors. These power relays must be small, and have a high contact pressure resistance to vibration. In addition to the basic structure, G8K / G8G / G8PM have a special feature: a small, high-capacity switching that is resistant to vibration.
Low load (1 to 5 A)
Middle load (up to 15 A)
High load (up to 40 A)
1 to 5 A
Small relay compatible with 24 VDC power supply
Basic structure with vibration-resistant contact pressure + miniaturization
Advancements in miniaturization, contact reliability and heat dissipation needed for DC rating for continuous energizing current
A focus on smaller mounting area requirements
OMRON's unique terminal arrangement simplifies the board wiring (layout), making further miniaturization possible.
A focus on miniaturizing for middle power relays
The industry's smallest class*2 mounting area for middle power relays.
A focus on contact reliability and heat dissipation required for high capacity 40 ADC
High contact reliability and high heat dissipation characteristics required for high capacity 40 ADC are made possible with OMRON's unique contact structure.
＊1. Twin type that combines the functions and structure of G8K-1 into a single package.
＊2. OMRON survey result, April 2022.
＊3. A patent has been obtained for the contact piece shape. The notation "patent pending/patented" indicates that a patent is pending or has been patented in Japan. (As of April 2022)
In addition to applications for autonomous mobile robots, the products can also be used for batteries for elevators during power outages, 24 VDC power supply control of FA equipment, and opening and closing of various DC motors, solenoid valves, solenoids, etc.
