DB120804-1-05N, LANBAO, sensor distribution box M12, 8 ports 4pin, PVC 5m, NPN

DB120804-1-05N is a sensor box with 8 four-pin M12 sockets, designed for mounting directly on the machine. The feed is a permanently attached 11-core PVC cable 5 m long: yellow-green PE, brown (+), blue (−) and eight signal wires – white, green, yellow, grey, pink, red, black and violet. The output is NPN with NO switching function. Each port has its own yellow LED, so sensor switching is visible directly on the machine.

When to choose this variant

• PVC jacket for static installation. The cheaper choice wherever the cable lies fixed in a duct and does not bend.
• 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.
• NPN version for machines with negative logic – typically Asian production lines and retrofits of older equipment.
• 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 PVC feed cable has 11 cores. The colours correspond to the individual ports as follows:

In the NPN version, the LED is connected to supply plus. 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

Can I connect PNP and NPN sensors to one box?

No. The box is made separately in PNP and NPN variants, and the logic must be the same for the sensors, the box and the PLC input card.

Can the feed cable be extended?

For variants with a fixed cable, the length is given by the type and extension requires a coupling in the control cabinet. It is therefore better to choose a longer variant.

Can it withstand washdown or coolant?

Yes. The box has IP67 protection: the interior is potted with epoxy resin, the contacts are gold-plated and the joint is sealed by an FKM O-ring that resists oils and coolant emulsions. Unused ports must be capped.
