LR12XBF04DPCU-E2 – Inductive sensor with correction factor 1 (factor 1)

LR12XBF04DPCU-E2 is an inductive sensor with correction factor 1 (factor 1) from LANBAO, size M12. It detects steel, stainless steel, aluminium, copper and brass at the same distance because, unlike a standard inductive sensor, it has no reduction factor depending on the type of metal.

Key features

• Sensing distance 4 mm.
• PNP output, NC contact – normally closed – connects to a PLC digital input or a relay coil.
• Connection: connector M12.

Technical specifications LR12XBF04DPCU-E2

Wiring of LR12XBF04DPCU-E2 by wire colours

Watch the cable choice: according to the manufacturer's catalogue, in the NC version with the M12 connector the output is on pin 2, i.e. the white wire. A three-pin cable M12 uses pins 1, 3 and 4 and pin 2 is missing, so for this sensor use a four-pin cable. The switched signal is then on the white wire, not the black one.

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).

Connection cable for LR12XBF04DPCU-E2

The sensor has a connector M12, 4 pins, male (external thread with pins), so it requires a cable with a femaleconnector. The cable is not included.

• QE12-N4G5-N – M12, 4 pins, female, angled 90°, 5 m, PVC, with LED indication

In this NC version the output is on pin 2, which a three-pin cable does not contain, so choose a four-pin cable.

PUR version: we do not yet stock a M12 female cable with a PUR jacket (for oils, coolant emulsions, abrasion, low temperatures and drag-chain installation). Contact us and we will source it. A cable with a PVC jacket is intended for normal dry machine environments.

The LED indication of the switched output in the connector is designed for the PNP NO version. With other output combinations the cable works electrically, but the indicator may not show switching – in that case choose a cable without indication.

Typical applications

• lines where parts made of different metals are mixed
• detection of aluminium and non-ferrous metals at full distance
• applications with stainless steel parts without loss of range
• setting one sensor for several materials
• eliminating errors caused by the reduction factor

How to choose and what to watch out for

• PNP output (switches plus) matches the standard PLC digital inputs used in Europe. For NPN-type inputs, choose the corresponding variant with the same sensing distance.
• NC contact (normally closed): the output is active at rest and opens on detection. It is used where a broken wire should cause the same reaction as a detection (safer logic).
• Connector connection M12: a separate connection cable with a matching connector is required for operation – you will find it in the Cables with connector category.

PNP or NPN – and what happens if you mix them up

PNP switches the positive pole, so it sends plus to the PLC input. It is the European standard and matches standard digital inputs. NPN switches minus and is used mainly in Asian equipment. If mixed up, the sensor either does not switch at all or reports a permanently active state — it usually will not be damaged, but it will not work.

This model has a PNPoutput. If you need NPN, a variant with the same sensing distance is available — contact us and we will recommend the code.

NO or NC – and why it is not just a matter of convenience

NO (normally open) is an output that is active on detection. NC (normally closed) is active at rest and opens on detection. The difference is a safety one: with NC, a broken wire causes the same reaction as a detection, so the fault shows up immediately. With NO, a broken cable remains unnoticed until someone tries to switch.

This model has the contact NC – normally closed.

Frequently asked questions

Does LR12XBF04DPCU-E2 have a PNP or NPN output?

LR12XBF04DPCU-E2 has a PNP output with an NC contact – normally closed. It therefore matches the standard PLC digital inputs used in Europe.

What is the sensing distance of LR12XBF04DPCU-E2?

The sensing distance (Sn) is 4 mm.

How is LR12XBF04DPCU-E2 connected?

LR12XBF04DPCU-E2 is supplied with the connection: connector M12. A connection cable with a matching connector must be ordered separately.

How many pins should the cable for LR12XBF04DPCU-E2 have?

According to the manufacturer's catalogue, in the NC version with the M12 connector the output is on pin 2, which a three-pin cable does not contain. Therefore use a four-pin cable – the switched signal is on the white wire.

Which cable do I need for LR12XBF04DPCU-E2?

Cable with a female M12 connector. We stock QE12-N4G5-N (4 pins, 5 m, PVC); for sensors with one output, three-pin QE12-N3G5-P or QE12-N3G5-N. can also be used. The cable is not included.
