Magnetic Switches
 |
Willow Technologies offer highly innovative miniature Magnetic Switches with high sensitivity and low supply voltage operation, integrating a single axis magnetic field sensor element with complete control and processing circuitry all on a single chip. The Magnetic Switches are minute at 1.1 x 1.0 x 0.57mm, operate with a 1.5V battery and are becoming smaller and lighter with every new development. Our Engineers are available to offer free support and advice on design in projects or simply on the most suitable solution for your requirements. |
