BELDEN PRESENTS NEW PROFIBUS-DP CONNECTORS FROM ITS RANGE OF LUMBERG AUTOMATION CONNECTIVITY PRODUCTS
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 (height x width x depth) 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.
