Mini-Dyad™
MN2
Features
• Small size
• SMT-compatible
• Easily formed leads
• Sputtered ruthenium contacts
• Hermetically sealed contacts
• Fast switching speed — up to 500Hz
• Wide range of available magnetic sensitivities
Description
Clare’s Mini-DYAD™ dry reed switches are ideally suited
for small switching signal applications. This switch has
sputtered ruthenium contacts and an extraordinary seal
strength, achieved by a patented laser sealing of the glass.
In low level or dry switching environments, both switches
typically provide >1 billion operations. The switches have
hermetically sealed contacts and offer a wide range of
available magnetic sensitivities.
Applications
• Security
• Proximity sensing
• Smoke alarms
• Automotive
• Level sensor
• Lamp current sensor
• Relays
