Signal switch manufacturer Coto Technology recently unveiled the RedRock RS-A-2515. Coming in a footprint of less than 2.1mm2 (1.01×2.08mm), the company's latest switch combines the inherent benefits of MEMS-based design with the advantages of conventional magnetic reed-switch technology. The SPST reed switch offers closure sensitivity ranges from 5mT to 25mT, permitting operation up to 20mm using a small NdFeB magnet.

The RedRock RS-A-2515 provides a release sensitivity of approximately 60 per cent of the closure sensitivity. This high level of hysteresis minimises the potential for sticking when the magnetic field is removed, which greatly adds to the switch's reliability. Maximum switching voltage is 100VDC with a switching current of 50mA DC or 35mA AC RMS. Zero operating power is beneficial in power-sensitive applications, particularly those operating from battery power.

Datasheet for the RedRock RS-A-2515 can be downloaded here.
