DB080803-2-03P, LANBAO, sensor distribution box M8, 8 ports 3pin, PUR 3m, PNP

DB080803-2-03P is a passive distribution box for 8 sensors with a three-pin M8 connector. The signals leave through a single PUR cable 3 m long; it contains 10 cores – brown (+), blue (−) and eight signal wires – green, white, grey, yellow, pink, red, violet and black. 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 3 m for a box placed close to the control cabinet – no excess that would have to be folded into the duct.
• PNP version matches the European standard and common PLC input cards from Siemens, Schneider or ABB.
• Eight M8 ports with a spacing of 14 mm. The highest connection density – for stations fitted with miniature photoelectric and inductive sensors.
• 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 3 m PUR feed cable has 10 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 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 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.

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.

Does the box contain any electronics?

No. The box is passive; the ports are only connected to the feed cable and supplemented with LED indication. Each channel therefore needs its own PLC input. If you want to transmit all signals over one network cable, you need an active I/O module with a fieldbus.
