The M12 connector is a circular connector with a 12-mm locking thread that is used primarily in factory automation applications for actuators, sensors, industrial ethernet, and Fieldbus. M12 connectors are designed for washdown and corrosive environments.
Which cable is used in Profibus?
The Cable. For Profibus networks a shielded AWG 22 or 0.34 mm² twisted pair cable is used. The standard isolation color of a Profibus DP cable is purple, and the two wires in the twisted pair are usually green and red.
What is Profibus connector?
The PROFIBUS DB9 connector is used in most IP 20 environments and is the best solution for high transmission speeds. The connector is perfect for establishing a connection between cables and to create the ideal branch. The majority of connectors have coils to suppress noise and reflections.
Can you splice Profibus cable?
Up to 1.5 Mbps, you can splice the cable any which way. Only be sure to get the screen connected well. At 12Mbps Profibus is much more finicky. You may have to exchange the cable ends for a uninterrupted cable all the way.
What is M12 D code?
D-coded for 100 Mbit Ethernet.
What is the difference between an M8 and M12 connector?
Circular M12 and M8 connectors are used in industrial automation to connect devices securely. M12 designs can also be used for fieldbus connections. The M8 connector is used specifically with industrial sensors. This connector features a waterproof 3-pin screw.
How does PROFIBUS connector work?
How does Profibus work? Profibus is also a master-slave type protocol like Modbus but with an additional token ring protocol to allow for multiple masters. Also, unlike Modbus, all devices go through a startup sequence during which they “join” the network. Each slave maintains a failsafe timer.
How many nodes can be connected to PROFIBUS?
In PROFIBUS networks, each segment can have a maximum of 32 nodes, counting master and devices. The maximum number of nodes with addresses in the overall network is 126. The available addresses for PROFIBUS devices are 0-126.
What is D-coded cable?
D-coded connectors are typically used in network cables for Ethernet and ProfiNet systems. D-coded connectors transfer data up to 100 Mb. These connectors typically provide three to five pins. X-coded connectors are a more recent advancement of the cables.
