Coto Technology claims industry's smallest MEMS reed switch
Press release, April 24; Michael McManus, DIGITIMES [Wednesday 24 April 2013]

Coto Technology, which has been designing and developing small signal switching solutions to the worldwide electronics industry for over 90 years, has announced the availability of its RedRock RS-A-2515 MEMS-based magnetic reed switch. The switch has a footprint of less than 2.5 mm2 (1.125 x 2.185 mm), is 0.95 mm high and Coto claims it is the smallest MEMS-based reed switch available on the market today.

Based on its 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.The solution targets applications in the medical, military, and industrial markets.

The Coto Technology RS-A-2515 MEMS-based magnetic switch is the first of a new Coto Technology switch family. The company noted the MEMS devices exhibits all of the 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 less 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.

The RS-A-2515 is available from stock in evaluation quantities at the unit price of US$29.95. Coto also provides an evaluation kit for US$49.95 in single piece quantities.
