CLARE UM2378

Ultra-Mini Dyad™
UM2
Features
• Small size
Easily surface mountable
• Hermetically sealed
• Easily formed leads
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
• Relays
• Telecommunications
• Automation control
• Medical

in excess of these ratings can cause permanent damage
to the device. Functional operation of the device at these
or any other conditions beyond those indicated in the
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings
for extended period may degrade the device and effect
its reliability.
