Profibus DP connectors support data rates up to 12 Mbit/s

Profibus DP connectors from Belden have a D-Sub and M12 interface with varying cable outlets and reduce downtime for machinery and equipment when faults occur, increasing production efficiency.


Belden IncBelden announced the availability of new Profibus DP connectors that have a D-Sub and M12 interface with 35°, 90° or 180° cable outlets. All versions support data rates of up to 12 Mbit/s and feature compact die-cast zinc housings with test socket and active terminating resistor. They also boast quick-connection technology that enables Profibus DP devices to connect with M12 Profibus cord sets simply and securely without the use of tools, resulting in the reduction of downtime for machinery and equipment when faults occur, while increasing production efficiency.

Robert Strehmann, Product Manager explains, “These new Profibus Connectors enable a clean approach to connecting M12 Profibus cords sets versus attempting to hardwire a SUB-D connector while eliminating the need to manually connect the shielding on SUB-D field installable connectors, which has lead to incorrect wiring in past applications.”

The connectors meet the requirements for degree of protection IP30 and are suitable for use in temperature ranges from -20 ° to +70 °C. The following housing dimensions are available: 59 x 45 x 16.8 mm for 35° cable outlets, 68 x 42 x 16.8 mm for 90° cable outlets, and 84.8 x 35.6 x 16.8 mm for 180° cable outlets. A special shielding geometry and the die-cast zinc housing ensure error- and loss-free data transmission.

The 9-pole D-Sub interfaces of the male and female connectors can connect high-level control systems, decentralized I/O stations, programming units or diagnostic devices. The B-coded M12 interfaces serve as a Profibus input or output and the signals can be daisy-chained via the output.

A slide switch activates the terminating resistor with the respective status indicated through the position of the switch and the green and red color-coding on the housing. In addition, an external Profibus terminating resistor can attach to the Profibus output port.
