What is this cable used for in industrial networks?

It is a pre-assembled PROFIBUS DP bus system cable designed for connecting PROFIBUS devices that use M12 B-coded interfaces, helping maintain consistent cabling and shielding performance in industrial environments.

Which connector types are fitted on each end?

It has a straight M12 B-coded plug on one end and a straight M12 B-coded socket on the other end, both shielded.

What is the cable length?

The cable is 0.5 m long (factory pre-assembled).

Is it suitable for PROFIBUS DP at 12 Mbps?

Yes. It is specified for PROFIBUS (up to 12 Mbps), using a PROFIBUS cable type designed for typical segment lengths up to 100 m (subject to network design rules and device requirements).

Which pins are used for the PROFIBUS signal pair?

The PROFIBUS pair uses pin 2 (green, A line) and pin 4 (red, B line), wired straight-through from plug to socket.

What are the electrical ratings (current and voltage)?

Rated current is 4 A (at 40°C). Rated voltage is typically stated as 48 V AC / 60 V DC for this assembly; UL listing data may reference up to 300 V depending on the approval context. Verify the required rating for the specific installation.

Is the cable shielded and what shielding does it use?

Yes, it is shielded. The cable uses a foil shield plus a tinned copper braided shield (high coverage), intended to support good noise immunity for industrial bus installations.

What is the characteristic impedance for PROFIBUS?

The nominal wave impedance is 150 Ω (typically ±10% over the stated frequency range), matching standard PROFIBUS cabling requirements.

What is the ingress protection (IP) rating when connected?

When properly mated, the connection is rated to industrial sealing levels, commonly stated as IP65 and IP67, with documentation also referencing IP69K for the connector system.

What is the operating temperature range?

For the connected plug/socket, the operating range is specified as -25°C to +90°C. For the cable itself, specifications commonly state down to -40°C (fixed installation) and down to -30°C (flexible installation), up to +80°C (and up to +70°C for drag chain applications).

What is the outer jacket material and colour?

The outer sheath is PUR (halogen-free) and violet (RAL 4001), which is commonly associated with PROFIBUS cabling identification.

What conductor size does it use?

It uses 2 x 0.25 mm² signal conductors (approximately AWG 24) with stranded construction suited to industrial movement requirements.

Is it suitable for moving applications such as cable carriers?

The cable specifications include bending cycle capability and minimum bending radii for flexible use. Typical values include a minimum bending radius of around 65 mm for movable installation and guidance for drag chain use (including a reduced maximum cable temperature in drag chain operation).

How tight should the M12 coupling nut be?

A typical tightening torque for the M12 connector coupling is 0.4 Nm. Using the correct torque helps achieve sealing performance and reduces the risk of loosening due to vibration.

Does it require a terminating resistor to work correctly on a PROFIBUS segment?

PROFIBUS segments generally require termination at the ends of the segment. This cable itself is not a terminating resistor; termination must be provided by the network’s end devices or by a dedicated termination component, depending on the installation.

Are the connections wired straight-through or crossed?

They are wired straight-through, with the PROFIBUS signal conductors maintained from plug to socket (pin 2 to pin 2 and pin 4 to pin 4). For reference, this matches the standard pin usage for M12 B-coded PROFIBUS.

How can I identify it in a panel or machine quickly?

Key identifiers include the violet PUR jacket (RAL 4001), M12 B-coded connectors on both ends, shielded construction, and the short 0.5 m assembly length. In some inventories it may be referenced as Phoenix Contact 1507353.
