What is the difference between Triacs and Thyristors? AC switching solid state relays use back-to-back Thyristors and TRIAC’s as their built-in output switching device. What is the difference between Triacs and Thyristors ? Working principles of Thyristors and Triacs Thyristor (or SCR) Thyristor also called SCR stands for Silicon Controlled Rectifier. It is a semiconductor […]
What is the cURus Approval ? The solid state relays and contactors made by celduc® relais are manufactured in compliance with cURus standard. Today we will give you more clarification about cURus approval. The cURus mark indicates that our products meet Canadian and U.S. safety standards. cURus is an approval from the UL, also named […]
What is a REED Switch? The REED switch is the sensitive element of the magnetic sensor. It detects the presence of a magnetic field, usually a permanent magnet. It detects without contact the position of the magnet and transmits an electrical on/off or analog signal depending on the model. Basic Principles A REED switch […]
M8 Reed proximity switches housed in a threaded barrel to enable easy fitting and adjustment. These M8 threaded sensors are built for mounting in threade holes. It is particularly useful in industrial applications where distance adjustments need to be made every now and then. So first, what does M8 stand for ? M8 is the […]
The evolution of the SSRs : From the hockey puck to the 22.5mm relay Since they were launched on the market in the early 1970s, solid state relays ( SSR s) have been evolving, covering a wider range of applications, from the industrial sectors up to demanding applications in the railway, aircraft and medical industries.
