The new MM9200 from Menlo Micro is the world’s first micromechanical power switch capable of handling 10 A in a miniature 5×5-mm surface-mount package. With its ultra-low 0.010-Ω contact resistance, the new MM9200 is said to be the lowest-loss and highest power capable micro-mechanical switch ever created.
The MM9200 targets a wide range of applications including industrial automation, smart building controls, advanced energy management systems, and many other space-constrained power distribution applications. The Ideal Switch’s scalable design and process technology allow designers to reimagine power distribution from micro-grid to smart circuit breakers all the way to smart point of load switching, enabling total management and control with a virtually loss-less solution.
The Ideal Switch exhibits extreme mechanical endurance typically in the billions of switching cycles, which provides 1,000x better lifetime than traditional electromechanical relays. This reliability, and its arc-free capability can reduce unplanned maintenance and replacement costs while bringing safety innovations not previously possible for industrial automation applications. In addition, the device’s 10-µsec actuation speed is more than 1,000x faster than its electromechanical equivalent, enabling entirely new concepts for power switching and protection.
Like all Menlo Micro Ideal Switch products, the MM9200 employs true metal-to-metal contacts which reduce losses and power dissipation by more than 90% when compared to solid-state devices. This design, combined with the Ideal Switch electrostatic drive, makes the MM9200 the most power efficient, and space efficient high-power switch in the market.
