DC Solid State Relays

Magnetic sensors

Used for monitoring or controlling levels, motion, movement, position and rpm recording. The sky’s the limit for these versatile sensors. These sensors are used both by the general public and in major industries, such as automotive, aircraft, telecommunication and automation.


Reed relays & switches

The Celduc Reed switches are used in Celduc’s magnetic proximity sensors, Reed relays and Reed switches. Tried and tested, they can last for over 60 years. The range meets the demands of an increasing number of new applications, thanks to their ease of use, compact size and reliability.
