A standard and its success story
22 November 2024
System designers are increasingly opting for MQ 15 connectors to supply power quickly, cost-effectively and safely to asynchronous or three-phase motors up to 7.5 kW or to frequency converters.
The standardisation of the pin assignments for AC and DC applications in accordance with the international standard IEC 61076-2-116 and the resulting guaranteed manufacturer-independent compatibility have further boosted this trend.
As Murrelektronik highlights, the innovative fast connection system reduces assembly time by up to 80 percent – and the connection is sealed to IP67.
As with its increasingly popular decentralised system solutions for automation without control cabinets, Murrelektronik is also prominent in the MQ 15 connectors field. MQ 15 connectors fit perfectly with the company's DNA: to make industrial automation as simple, seamless and cost-efficient as possible with smart solutions.
In this case, there is another important advantage: the compact design. The MQ 15 connectors transmit high currents in the smallest of spaces – making them suitable for systems where space is limited.
Instead of always relying on expensive M23 connectors – and thus incurring unnecessary costs in some cases without any meaningful benefit – Murrelektronik has also developed an extensive series of MQ 15 connectors that can cover a wide range of applications with power transmission values of up to 16A continuous load at a voltage of 600V for AC applications, and 20A at a voltage of 48V for DC applications. Thanks to CE certification and UL approval, these may be applied all over the world.
Quality combined with attractive price/performance ratio
In addition to these benefits due to the standard, Murrelektronik's MQ 15 connectors have a number of technical features that make life easier for customers.
For example, the innovative quick-release system reduces the time required for installation, service and maintenance by up to 80 percent. Via a quarter turn, an audible and perceptible "CLICK" indicates that a successful connection has been made, and that power is flowing.
The connection is dust- and splashproof to IP67, as well as shock- and vibration-resistant, making it fully suitable for industrial use, even in harsh conditions. The hard silver-plated contacts guarantee long life (up to 500 mating cycles), while the ready-to-connect cables feature full PUR overmoulding.
For optimal price-performance ratio, Murrelektronik also uses high-performance plastics for its MQ 15 connectors, instead of expensive metal parts.
There appear to be many good reasons to rely on this standard and MQ 15 connectors from Murrelektronik in the future.
