New Profibus DP connectors from Belden's Lumberg Automationâ„¢ range

By Wendy McWilliams

Quick-connection technology enables use of M12 cord sets.

Belden has extended its range of Lumberg Automationâ„¢ products to include new Profibus DP connectors.

These connectors each have a D-Sub and M12 interface, and are offered with 35°, 90° or 180° cable outlets. All versions support data rates of up to 12 Mbit/s and feature compact die-cast zinc housing with test socket and activatable terminating resistor.

They also boast quick-connection technology that enables Profibus DP devices to be connected with M12 Profibus cord sets simply and securely without the use of tools. Because the shielding no longer has to be attached manually, errors are reduced. A key advantage is reduced downtime of machinery and equipment when faults occur, thus increasing production efficiency.

The connectors meet the requirements for an IP30 rating 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 die-cast zinc housing ensure error- and loss-free data transmission.

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

The terminating resistor of the connectors can be activated via a slide switch. with the respective status being indicated both through the position of the switch and through green and red colour coding on the housing. In addition, an external Profibus terminating resistor can be attached to the Profibus out port.

The new Profibus DP connectors from Belden's Lumberg Automationâ„¢ product range not only enable fast and secure data transmission, but also tool-free installation.
