Description
LR18XCN08LI4M – Inductive sensor with analogue output (distance measurement)
LR18XCN08LI4M (LANBAO) is an inductive sensor with analogue output (distance measurement). Instead of a switching output, it provides a continuous signal proportional to the distance of the metal object, so it can measure position, not just detect presence.
Key features
- Sensing distance 1.6-8mm – rated value for a standard steel target.
- Supply 10–30 V DC.
- Connection: cable 2 m.
- Degree of protection IP67 – protection against dust and temporary immersion.
How an inductive sensor works
The coil in the sensing face generates a high-frequency magnetic field. When a metal object enters the field, it induces eddy currentsin its surface, which draw energy from the field and dampen it. As soon as the damping exceeds the set threshold, the evaluation circuit switches the output. All this happens without any contact, so the sensor has no mechanically wearing parts.
High-frequency oscillation principle: coil field, eddy currents in the metal target and their damping effect.
Correction factor – why the range on aluminium differs from steel
The rated sensing distance applies to a standard steel target. For other metals it is reduced by a correction factor. Calculate the actual distance as the rated Sn multiplied by the material factor.
| Steel St37 (standard target) | 1.0 |
|---|---|
| Cast iron | 0.93 – 1.05 |
| Aluminium | 0.60 – 1.00 |
| Stainless steel | 0.65 – 0.75 |
| Brass | 0.35 – 0.50 |
| Copper | 0.25 – 0.45 |
| Nickel | 0.25 – 0.45 |
Standard target and tolerance
According to the manufacturer's catalogue, the standard target is a square plate of St37 steel, 1 mm thick. The side length equals the larger of: the diameter of the sensing face, or three times the sensing distance. A smaller target means a shorter range. The sensing distance tolerance is ±10 %, so never set the working point exactly at the Sn limit.

Wiring of LR18XCN08LI4M by wire colours
| Wire | Colour | Wiring |
|---|---|---|
| 1 | brown (BN) | + supply (L+), 10–30 V DC |

Voltage or current? A voltage output is simpler for short runs. A 4–20 mA current loop is resistant to interference and to voltage drop on the line, so it is more suitable for longer cables and environments with frequency inverters and motors. Route the analogue signal cable separately from power conductors – otherwise interference will show up as fluctuation of the measured value.
The colour coding complies with IEC 60947-5-2. Always compare the actual pin and wire assignment with the diagram in the sensor datasheet (Downloads tab).
Typical applications
- measuring and monitoring the position of a metal part within a defined range
- checking tolerance and deviation from a set position
- measuring the thickness and deflection of metal components
- monitoring play and wear in mechanisms
- feedback to a PLC control loop
How to choose and what to watch out for
- Cable outlet: the cheaper variant, but replacing the sensor requires pulling the entire cable. If you need quick replacement, choose a model with a connector (suffix -E1 for M8, -E2 for M12).
- Degree of protection IP67: protection against dust and temporary immersion. Not designed for permanent immersion or high-pressure washing – this requires IP69K.
- Sensing distance 1.6-8mm is the rated value for a standard steel target. For stainless steel, brass, aluminium or copper it is reduced by a reduction factor – if you detect non-ferrous metals, allow a margin or choose a model with correction factor 1.

Frequently asked questions
What is the sensing distance of LR18XCN08LI4M?
The sensing distance (Sn) is 1.6-8mm. This is the rated value for a standard steel target; the range is shorter for non-ferrous metals.
How is LR18XCN08LI4M connected?
LR18XCN08LI4M is supplied with the connection: cable 2 m. The cable is part of the sensor; the other end is free for connection to a terminal block.
Which wire carries the analogue signal on LR18XCN08LI4M?
For the 0–10 V voltage output it is the black wire (pin 4), for the 4–20 mA current output the white wire (pin 2). Models with both outputs provide both signals simultaneously, so they require a four-pin cable.
Should I choose the 0–10 V or the 4–20 mA output?
It depends on distance and interference. The 0–10 V voltage output is simpler for short cables; the 4–20 mA current loop is resistant to interference and line voltage drop, so it is more suitable for longer runs and noisy environments.
Are there other variants of LR18XCN08LI4M?
In the same series we offer models with the same sensing distance and a different output type, contact function or connection: LR18XCN08LIUM-E2.
