Coto CT05 Series

Coto CT05 Series
The CT05 moulded dry reed switch series from Coto. It is single-pole, single throw (SPST) type, having normally open ruthenium contacts. The total operating range of 15AT to 50AT with a release range of 5AT to 45AT and a switched power of 5W (max). The CT05 series is a double-ended type and may be actuated with an electromagnet, a permanent magnet or a combination of both. The device is designed with rugged encapsulation, excellent life and reliability, SMD mounting and is available in Gull Wing or J-lead configurations. The CT05 series are ideally suited to the needs of proximity sensing, medical applications, hearing aids and pulse counter.
