Lumberg Automation L-coded M12 power connectors

The Lumberg Automation L-coded M12 power connectors are approved in accordance with UL and VDE, and are offered in both straight and angled versions, as well as moulded, for customer assembly or as an installation variant. They have an extended operating temperature range of -40 to +125°C and are available with protection classes IP65, IP67 or IP69K. The five-pin versions with functional ground are clearly recognisable by a grey cable jacket and grey contact carriers for pins and sockets.

At its technical strategy meeting this September, PROFINET International (PI) decided that the L-coded variant, which is internationally standardised through the standard 61076-2-111, will be the future single standard for 24 V Profinet devices with round connectors. The key factors behind this decision were compact design and its high current-carrying capacity (16 A) at a conductor cross-section of 1.5 mm².

In addition, L-coded M12 Power Connectors for Profinet devices in a TN-S system can be connected via the fifth contact for the functional ground to a common bonding network (CBN), a meshed grounding concept in accordance with DIN EN 50310.
