Inductive Proximity Sensor M12, 4mm Range, NPN NO, 1pc
✔️ 3-wire NPN NO, 1.2 m cable, 6-36V DC, 4mm sensing range

Inductive proximity sensor is a compact, non-contact metal detector used across automation lines. It’s commonly mounted as limit switches, positioners, or counting sensors on machines in metalworking, textile, packaging, and chemical industries.

✅ 6-36V DC supply, 300 mA max, NPN NO output for easy interfacing
✅ 4 mm (0.16 in) sensing range for fast metal detection
✅ M12 threaded housing with nickel-plated brass body for harsh environments
✅ 1.2 m (4 ft) cable length for flexible mounting

💡 What is an inductive proximity sensor used for in industrial automation and metalworking?

In general, it detects metal targets without physical contact and signals controllers for non-contact limit switching and positioning.

• inductive proximity sensors are handy for limit switches in conveyors and machines
• they enable precise counting and positioning in assembly lines
• they perform reliably in metal-heavy environments with minimal maintenance
