Coto Technology RedRock MEMS-Based Reed Switch

Coto Technology RedRock™ MEMS-Based Reed Switch

      Coto Technology RedRock™ MEMS-Based Reed Switch is ideally suited to the needs of medical, industrial, automotive, and other applications where small size, zero power operation, and hot switching capabilities are required, the RedRock™ MEMS-Based Reed Switch is a single-pole, single throw (SPST) device with normally open ruthenium contacts.
      The sensor may be actuated by an electromagnet, a permanent magnet, or a combination of both. Based on its unique high aspect ratio MEMS design and manufacturing processes, the switch provides all of the advantages of conventional magnetic reed switch technology, including zero power operation and high-power hot switching. Coto has married these features to the inherent benefits of MEMS-based design and manufacture, including item-to-item uniformity, robustness and small size by using wafer level packaging (WLP). The resulting solution meets the demanding requirements of applications in the medical, military, and industrial markets.
      The switch has a footprint of less than 2.1 mm2 (1.01 x 2.08 mm), is 0.94 mm high and is the smallest MEMS-based reed switch available on the market today. The Coto Technology RS-A-2515 MEMS-based magnetic switch, the first of a new Coto Technology switch family, exhibits all of the high performance characteristics inherent in classical reed switches. These include closure sensitivity ranges from 5 to 25 millitesla, permitting operation up to 20mm using a small NdFeB magnet. This provides it with the ability to address a wide range of applications. The switch has a release sensitivity greater than 15 millitesla (5mT), minimizing the risk of sticking when the magnetic field is removed. The RS-A-2515 has a maximum switching voltage of 100 VDC with a switching current of 50mA DC or 35mA AC, RMS. The zero operating power is a critical advantage in power sensitive applications, particularly those operating with battery power.
      Marrying these major performance advantages with the inherent benefits of batch processed MEMS technology including wafer level hermetic packaging, low-cost manufacturability, and item-to-item reproducibility provide a truly unique advantage for its selection in demanding applications.
