Automotive power relays in mainstream supply in China have a maximum mechanical life span of 10 million cycles.
For automotive applications, China's typical power relays have 12 or 24VDC rated voltage, more than 10A switching current, and 50mohm maximum contact and 100Mohm minimum insulation resistance. These support an operating temperature range of -40 to 125 C and boast a mechanical life span of up to 10 million cycles.
Ningbo Yod Electronic Technology Co. Ltd offers a model with capability to safely switch up to 1,400 or 2,800W and 120, 140 or 200A. The switching voltage is 40VDC. The 1 Form H unit has a rated coil voltage of 6, 12, 24 or 48VDC, maximum contact resistance of 100mohm and minimum insulation resistance of 100Mohm. Its operating temperature is -40 to 85 C. The relay weighs approximately 90g.
The main materials and components in manufacturing automotive power relays include coils, reeds, armatures and wires. All come from local sources, although there are some suppliers that purchase reed and contact inputs from abroad to ensure high quality. Ningbo Yod uses reed materials from South Korea and silver alloy from Japan.
Despite the rise in the cost of manufacturing inputs, most relays makers opted to maintain prices. They expect this trend to persist in 2018, while others may raise quotes due to the higher outlay.
The products in this gallery have been handpicked by our China-based market analyst for representing current trends in automotive power relays from China makers.
