Since the introduction of the famous and today widely used RT style relay 25 years ago the market is waiting for a next generation solution offering new features and advantages to hardware designers. The brand new GQ 16A version of GOODSKY represents the next level of miniaturization as this component reduces the space needed on the PC board compared to the standard available today by half.


Based on the strong partnership of CODICO and GOODSKY the two companies decided to work on the roadmap of a next generation 16A relay to provide the market a smarter solution compared to today's well introduced RT standard and took the GQ relay platform as the basis to design this new product.


The objectives for the specification of this next generation relay were as follows:
• Considerable reduction of space requirementin comparison to todays solution
• Reinforced insulation despite reduced length
• Enable double layout to RT/RZ style relays
• High ambient temperature up to 105°C
• A reflow version with reasonable price added
• Fully automated production line to secure highest product reliability and quality level


Reflow soldering profile

The designers of GOODSKY took the challenge and worked on modification of the inner structure both coil- and contact system. Intensive testing of the electrical performance for resistive as well as high capacitive inrush loads showed that the design objectives are meet. We are now able to offer a very small and powerful universal power-pcb-relay for a number of applications such as for wet-, cool- and hot platforms in the appliances industry, applications in smart homeand building automation, light controls, motor controls, heating controls, industrial controls and the use in measurement and instrumentation circuits.
