DB080403-2-05N, LANBAO, sensor distribution box M8, 4 ports 3pin, PUR 5m, NPN

DB080403-2-05N is a sensor distribution box with 4 ports M8 in the 3-pin version. The feed is a permanently attached 6-core PUR cable 5 m long: brown (+), blue (−) and four signal wires – green for port 1, white for port 2, grey for port 3 and yellow for port 4. 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

• 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.
• NPN version for machines with negative logic – typically Asian production lines and retrofits of older equipment.
• Four ports in 90 mm of length. Fits even where there is no room for an eight-port box.
• 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 2 A per port, 8 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 6 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 4 cables with M8 connector / 3 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 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.

Can I also use the box for actuators, not just sensors?

Yes, as long as you stay within the port current rating. The box is passive and does not process the signal in any way, so it can also carry outputs to valves or indicator lamps.

What happens to the degree of protection if I leave a port unused?

IP67 protection only applies if every socket is either fitted with a connector or closed with a cap. An open port is a path for dust and moisture and reduces the protection of the whole box.
