Coto Classic CT Molded Switches and Sensors

CotoClassic™ Molded Reed Switches

Coto Classic CT05 and CT10

Coto Classic Molded Switches are the single-pole, single throw (SPST) type, having normally open ruthenium contacts. The sensor is a double-ended type and may be actuated with an electromagnet, a permanent magnet or a combination of both. The CT05 (5mm / 5W) is designed for SMD mounting and is available in Gull Wing or J-Lead configurations. The CT10 (10mm / 10W) is designed for SMD mounting and is available in Gull Wing, J-Lead, and axial configurations.  All CT Molded Switches are 100% tested AFTER lead forming to ensure superior reliability in the field.  Note: The new CT10-G2 is 260°C process temperature hardy!   Download CT05 Datasheet       Download CT10 Datasheet
