Inductive sensor SND04 N2, NPN NC

The SND04-N2 inductive proximity sensor is a compact non-contact sensor designed for reliable detection of metal objects. It uses the principle of inductive sensing, which makes it resistant to dirt, dust and moisture. The version with NPN NC (normally closed) output is suitable for industrial control systems, automation, machines and production lines, where the emphasis is on stable and fast response.
