DB120805-2-05N, LANBAO, sensor distribution box M12, 8 ports 5pin, PUR 5m, NPN

DB120805-2-05N is a sensor distribution box with 8 ports M12 in the 5-pin version. The feed is a permanently attached PUR cable 5 m long runs to the control cabinet. It contains a PE conductor, supply wires and two signal wires for each port: yellow-green PE, brown (+), blue (−) and for each of the eight ports two separate signal wires for pin 4 and pin 2. 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.
• Five pins per port. In addition to the supply and the switching output, you can also carry a second signal or shielding – for sensors with two outputs, analogue or diagnostics.
• 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 PE, supply and two signal wires for each port. 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 / 5 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.
