LR12XBF15DPOB-E2 – High-pressure inductive sensor

LR12XBF15DPOB-E2 from LANBAO is an inductive sensor for pressure applications with a specified resistance up to 500 bar. The ambient operating temperature is −25 °C to +80 °C; it is not intended for higher temperatures. Verify the suitability of installation in a hydraulic system according to the manufacturer's datasheet.

Technical specifications LR12XBF15DPOB-E2

Wiring of LR12XBF15DPOB-E2 by wire colours

The sensor uses pins 1, 3 and 4 of the M12, connector, so a three-pin cable M12 is sufficient; a four-pin cable can also be used.

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).

Connector pin assignment according to the manufacturer's catalogue.

Connection cable for LR12XBF15DPOB-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
• QE12-N3G5-P – M12, 3 pins, female, angled 90°, 5 m, PVC, with LED indication PNP
• QE12-N3G5-N – M12, 3 pins, female, angled 90°, 5 m, PVC, with LED indication NPN

The sensor has one output, so a three-pin cable is sufficient. A four-pin cable can also be used – the fourth wire remains unconnected.

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

• hydraulic cylinders and pressure systems
• hydraulic systems at ambient temperatures up to +80 °C
• sensing piston position through a pressure wall
• forming and injection moulding machines
• pressure applications up to 500 bar at ambient temperatures from −25 °C to +80 °C

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.
• NO contact (normally open): the output is activated when an object is detected. If you need the opposite logic, an NC variant is available.
• Connector connection M12/4 pins: a separate connection cable with a matching connector is required for operation – you will find it in the Cables with connector category.
• Degree of protection IP68: check immersion and cleaning conditions in the datasheet; IP68 by itself does not mean resistance to high-pressure washing.

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 NO – normally open.

Frequently asked questions

Does LR12XBF15DPOB-E2 have a PNP or NPN output?

LR12XBF15DPOB-E2 has a PNP output with an NO contact – normally open. It therefore matches the standard PLC digital inputs used in Europe.

What is the sensing distance of LR12XBF15DPOB-E2?

The sensing distance (Sn) is 1.5 mm.

How is LR12XBF15DPOB-E2 connected?

LR12XBF15DPOB-E2 is supplied with the connection: connector M12/4 pins. A connection cable with a matching connector must be ordered separately.

How many pins should the cable for LR12XBF15DPOB-E2 have?

The sensor uses pins 1, 3 and 4, so a three-pin cable is sufficient; a four-pin cable can also be used. The signal is on the black wire, plus on the brown and minus on the blue.

Which cable do I need for LR12XBF15DPOB-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.
