DB120804-2-05P, LANBAO, sensor distribution box M12, 8 ports 4pin, PUR 5m, PNP

DB120804-2-05P is a passive distribution box for 8 sensors with a four-pin M12 connector. The signals leave through a single PUR cable 5 m long; it contains 11 cores – yellow-green PE, brown (+), blue (−) and eight signal wires – white, green, yellow, grey, pink, red, black and violet. The output has PNP logic and NO switching function. Diagnostics are made easier by a yellow LED above each port.

When to choose this variant

• PUR jacket for moving installation. Withstands repeated bending in a drag chain, oil and coolant emulsion, and resists abrasion better than PVC.
• Cable 5 m is the most frequently requested length: it covers the usual distance from the machine to the control cabinet with a small margin.
• PNP version matches the European standard and common PLC input cards from Siemens, Schneider or ABB.
• M12 with four pins is the most widespread combination in industry – it fits most switching sensors without adapters.
• Degree of protection IP67. Potted interior, gold-plated contacts and an FKM O-ring – withstands dust, washdown and coolant emulsion. The condition is that every port is either occupied or closed with a cap.
• Current rating 4 A per port, 10 A in total. Enough even for fitting all ports with inductive sensors with higher consumption.

Technical specifications

Parameters according to the Lanbao manufacturer's catalogue (Industrial connection system). The material and length of the feed cable can be customised on request.

Feed cable wire assignment

The 5 m PUR feed cable has 11 cores. The colours correspond to the individual ports as follows:

In the PNP version, the LED is connected to supply minus. Port numbering corresponds to the print on the box cover.

What needs to be ordered additionally

The box is supplied without cables to the sensors. For full occupation, order 8 cables with M12 connector / 4 pins, male. To connect to the sockets of the distribution box, use the following Lanbao male cables and connectors:

The suffix -U denotes a PUR jacket, without it the cable is PVC; F is the straight and G the angled version. Close unused ports with a suitable cap to maintain the box's degree of protection.

Frequently asked questions

Are the sensor cables included in the price?

No. The price covers the box with its feed cable only. Cables or connectors for the sensors are ordered separately, in a number corresponding to the number of ports.

How do I find out that a sensor is not switching?

By the yellow LED at the corresponding port. It lights up when the sensor is active, so you can find the fault directly on the machine without searching through the PLC inputs.

How is the box mounted?

With two through-holes in the base. You will find the spacing and diameter of the holes in the parameter table above; the dimension drawing can be downloaded as a PDF.
