## Description

Inductive proximity sensor for non-contact detection of metal objects, ideal for industrial automation and DIY projects. Non-flush M18 mounting with a 10 mm detection distance, 6-36 VDC supply, and PNP NO output compatible with PLCs and microcontrollers. Rugged IP67 housing with status LED and integrated 2 m cable for quick connection.
Inductive sensor from the LJA series designed for contactless detection of metal objects. The cylindrical body with a diameter of 18mm (M18) allows quick mounting in various industrial applications or DIY projects. The LJA18M-10P1 variant features a detection distance of 10 mm, PNP output, normally open (NO), operates at a supply voltage range of 6-36 VDC, and comes with a 2-meter integrated cable with 3 wires. The sensor is of the non-flush (non-embedded) type.
The status LED indicates the presence of an object within the detection range, and the integrated protections (short circuit, reverse polarity) ensure safe operation in industrial environments.

Usage:
Install the sensor on an M18-compatible mount, ensuring a clear distance from other metal objects that could interfere with detection.
Connect the brown wire to the power source (6-36 VDC), the blue wire to ground, and the black wire to the controller input (PLC, Arduino, relay, etc.).
For stable operation, it is recommended that the working distance be set to a maximum of 70% of the standard detection distance. The standard detection distance (10 mm) applies to iron. For other metals, the effective distance is calculated by multiplying the standard detection distance by the corresponding correction coefficient:
Steel: ~0.9
Brass: ~0.7
Chrome-nickel: ~0.6
Aluminum: ~0.4
In the absence of a metal object in front of the sensor, the output is OFF (zero voltage). When a metal object enters the detection range, the output switches to the supply voltage (positive), activating the connected load. The built-in LED lights up simultaneously.
Attention!
Do not exceed the maximum output current of 300 mA; for large loads (gear motors, bulbs, etc.), use an intermediate relay.
In applications with strong interference, install an overvoltage protection device.
Do not use the sensor within the first 100 ms after powering on, as this is the stabilization period.
