Datasheet UM2S1030, UM2S1020, UM2S1015, UM2378, UM2376 Datasheet (CPCLARE)

Features Description

• Small size

Easily surface mountable

• Hermetically sealed

• Easily formed leads

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

Ordering Information
