CT10 Series Encapsulated Molded Dry Reed Switches Coto Technology CT10 Series Encapsulated Molded Dry Reed Switches are single-pole, single-throw (SPST) types that have normally open ruthenium contacts. The double-ended sensor can be actuated with an electromagnet, a permanent magnet, or a combination of both. The CT10 (10mm / 10W) series is designed for SMD mounting and is available in multiple gullwing and axial configurations. Coto Technology CT10 Series Encapsulated Molded Dry Reed Switches are tested for operation and release sensitivity after lead cropping and encapsulation to ensure superior reliability in the field. Common applications include proximity sensing, medical devices, and more.
