SN04-N Inductive Proximity Sensor Detection Switch, 4mm, 10-30V DC

The SN04-N is an inductive proximity detection switch designed for non-contact sensing of magnetic metals at a distance of up to 4mm. Operating across a wide 10 to 30V DC supply range, it delivers an output current of up to 300mA. It is well suited for makers, educators, and hobbyists building automation, positioning, or limit-detection systems.

Non-contact metal detection

The sensor reliably detects magnetic metal objects within a 4mm range. Non-contact inductive operation eliminates mechanical wear during repetitive position sensing.

Wide operating voltage

Designed for DC power systems, the switch runs on an input supply of 10 to 30V DC. It provides a switched output current capacity of up to 300mA.

Compact rectangular housing

With external dimensions of 18x18x36, the unit offers a space-efficient form factor for mounting onto custom fixtures, frames, and machinery.
