Dry Reed Relays
Contacts are made from ferromagnetic material (reeds). These contacts are encapsulated in glass. An energizing coil is wrapped around the glass and an EMF brings the two reeds together, closing the contacts.
Main Advantages
• Hermetically sealed, reduces oxidation build-up
• High Isolation (about 1014 O)
Main Disadvantages
• EMFs effect adjacent relays – requires shielding of relays in high-density applications.
• Inconsistent contact resistances
