DB080403-2-03P, LANBAO, sensor distribution box M8, 4 ports 3pin, PUR 3m, PNP

DB080403-2-03P combines the signals from 4 sensors with a three-pin M8 connector into one common line. The feed is a permanently attached 6-core PUR cable 3 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 PNP 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 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.
• 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 3 m PUR 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 operating temperature?

From −20 to +80 °C. The base is made of glass-filled polyamide PA66 the interior is potted with epoxy resin and the seal is an FKM O-ring.

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.

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.
