Description
Clare’s Ultra-Mini DyadTM is well suited for small, signal
switching applications. The small size lends itself to surface
mountable applications; working well on higher density
PC boards. The Ultra-Mini DyadTM has sputtered ruthenium
contacts and an extraordinary seal strength achieved by
a patented laser sealing of the leads. In low level or dry
switching environments, switches typically exceed 1 billion
operations.
Applications
• Proximity Sensors
