Inductive Proximity Sensor LJ12A3-4-Z/AY Twidec /M12 Approach NPN Output 300ma (Detection 4 mm)

The lj12a3 4 z by inductive proximity sensor from Micron Robotics delivers reliable and accurate metal detection in demanding industrial environments. Built with a rugged M12 housing, this sensor detects iron and other metals using eddy current induction, ensuring fast response without physical contact, wear, or sparks.

Operating on DC 6–36V with an NPN normally open output (300mA), the lj12a3 4 z sensor integrates seamlessly with PLCs and industrial controllers. Its high switching frequency, excellent repeatability, and LED status indicator make it suitable for precision positioning, mold detection, and stroke monitoring.

Designed for harsh conditions, this inductive proximity sensor is IP65 rated, resistant to dust, water, oil, and vibration. Additional protections such as reverse polarity and short-circuit protection enhance durability and safety. Easy installation and shielded design ensure stable performance even in interference-prone environments.
