The PR12-4DN Proximity Sensor Switch is a contactless inductive switch used to detect the presence of metal objects without physical touch. It is a practical control component for irrigation pump panels, water level and position sensing, conveyor lines, and small automation projects. It suits farms, workshops, and DIY builders who need a reliable on/off sensing signal for machinery and control circuits.
Key features
- Model PR12-4DN inductive proximity switch for contactless metal detection.
- No moving parts, so it works without mechanical wear from repeated triggering.
- Compact cylindrical body that mounts easily into panels and machine frames.
- Common DC-type wiring that fits typical relays, PLCs, and control circuits.
Typical uses
- Sensing position or limits on automated gates, pumps, and machines.
- Triggering relays or PLC inputs in irrigation and control panels.
- Detecting metal parts on conveyors or in workshop equipment.
- Object presence sensing in small automation and prototype projects.
How to choose / tips
- Confirm the PR12-4DN model matches your controller's input type before wiring.
- Mount it close enough to the target metal for stable switching.
- Keep wiring tidy and away from heavy electrical noise for clean signals.
