Dear teachers, has anyone used safety relays? Which well-known brand is used the most? What is the model number?

In a project designed 10 years ago, Weilong’s SNA4043K was used. Systems for domestic projects rarely employ safety relays, and I’m not very familiar with this brand either. I just know it’s quite expensive: lol, for reference only!

Pilz – no explanation provided; it’s a German brand from AB, a brand designated by P&G

The key question is: what is the working principle of this safety relay? In what situations is it used?
