DB080403-1-07P, LANBAO, sensor distribution box M8, 4 ports 3pin, PVC 7m, PNP

DB080403-1-07P is a passive distribution box for 4 sensors with a three-pin M8 connector. A single fixed PVC cable 7 m long runs to the control cabinet – brown (+), blue (−) and four signal wires – green for port 1, white for port 2, grey for port 3 and yellow for port 4. The box is in the PNP version with NO output. The yellow LED at each socket shows the channel status without you having to go to the PLC.

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 7 m reaches even the far end of a conveyor or line without having to insert a coupling into the route.
• PNP version matches the European standard and common PLC input cards from Siemens, Schneider or ABB.
• 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 7 m PVC feed cable has 6 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 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

What is the difference between the PVC and PUR variants?

PVC is cheaper and sufficient for a fixed route. PUR withstands repeated bending, oil and mechanical abrasion, so it belongs in drag chains and on moving machine parts.

What is a passive sensor distribution box for?

It combines the signals of several sensors into one common line. Each sensor plugs into a port on the box, and only one cable then runs from the machine to the control cabinet. This shortens installation, cable length and the number of places where a wiring error can occur.

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.
