MURRELEKTRONIK M12

Murrelektronik is a German manufacturer of industrial automation components, founded in 1975 and headquartered in Oppenweiler, Germany. The company produces power supplies, interfaces, IO systems, and connection technology. Its M12 product line centers on circular connectors and passive sensor junction blocks, widely used to consolidate discrete sensor signals in factory automation. The M12 family includes the EXACT12 and MVP12 series, which are passive distribution blocks without homerun cables. These blocks aggregate multiple sensor inputs into a single connection point, reducing wiring complexity and simplifying maintenance. 3G Electric supplies Murrelektronik M12 sensor junction blocks globally, with 22 SKUs currently available. The range covers 4-port and 8-port configurations, with 4-pole and 5-pole M12 female connectors. Electrical designs include NPN and PNP output types. Housing options comprise plastic and nickel-plated zinc die-cast, with IP65 or IP67 ratings depending on the model. Many blocks are designed for use with screw terminal caps, such as 9-pole, 12-pole, 14-pole, and 16-pole versions. These junction blocks are typically installed in control cabinets, machine frames, and conveyor systems where multiple sensors need to be connected to a PLC or I/O module. The passive design means no additional power supply is required for the block itself; it simply routes signals from sensors to the control system. This makes them suitable for applications where sensors are powered separately or where only signal consolidation is needed. 3G Electric provides access to datasheets, technical specifications, and logistics support for the Murrelektronik M12 line. The product data includes manufacturer part numbers, port counts, connector pole counts, electrical design, IP rating, housing material, and compatible terminal caps. This allows engineers and procurement specialists to match the correct junction block to their existing sensor and cable infrastructure. The M12 connection standard is defined by IEC 61076-2-101, ensuring interoperability with a broad range of sensors and cordsets. Murrelektronik M12 junction blocks are used across industries including automotive, packaging, material handling, and general factory automation. The EXACT12 series typically features a compact rectangular housing, while the MVP12 METAL series uses a nickel-plated zinc die-cast housing for applications requiring additional mechanical robustness. Both series are passive, meaning they do not require configuration or addressing. Installation involves mounting the block, connecting sensor cables to the M12 ports, and wiring the homerun side to a terminal cap or directly to the control system. The IP65 and IP67 ratings indicate protection against dust and water ingress, making them suitable for washdown areas and harsh industrial environments. 3G Electric maintains inventory and provides global shipping for these components, supporting both new installations and replacement needs. The company also offers technical documentation to assist with selection and integration.

Frequently asked questions

Common questions about MURRELEKTRONIK M12 from 3G Electric.

What is the difference between the Murrelektronik EXACT12 and MVP12 METAL series?

The EXACT12 series typically uses a plastic housing and is available in 4-port and 8-port configurations with IP65 or IP67 ratings. The MVP12 METAL series, such as SKU 852U92 (MPN 8000-58520-0000000), features a nickel-plated zinc die-cast housing with an IP65 rating and 8 ports. The metal housing provides additional mechanical protection in environments where impact or vibration may be present. Both are passive sensor junction blocks without homerun cables and use M12 female connectors. Selection depends on port count, connector pole count, electrical design (NPN or PNP), and required ingress protection.

How do I choose between NPN and PNP Murrelektronik M12 junction blocks?

The choice between NPN and PNP depends on the output type of the sensors and the input requirements of the PLC or I/O module. NPN sensors sink current to ground, while PNP sensors source current from the positive supply. The junction block must match the sensor output type to ensure correct signal transmission. For example, SKU 852UA4 is an NPN block with 4 ports and 4-pole M12 connectors, while SKU 852UG6 is a PNP block with 8 ports and 5-pole M12 connectors. Always verify the sensor datasheet and the PLC input card specifications before selecting a block.

What screw terminal caps are compatible with Murrelektronik M12 junction blocks?

Compatibility depends on the specific junction block model. For instance, SKU 852UA4 (MPN 8000-84401-0000000) is designed for use with a 9-pole screw terminal cap. SKU 852UC5 (MPN 8000-84500-0000000) uses a 12-pole cap. SKU 852UE5 (MPN 8000-88401-0000000) requires a 14-pole cap. SKU 852UC6 (MPN 8000-84501-0000000) and SKU 852UC7 (MPN 8000-84502-0000000) are designed for 16-pole caps. The terminal cap provides the homerun connection point for wiring to the control system. Using the correct cap ensures proper pin alignment and secure electrical connections. Refer to the block datasheet for the exact terminal cap specification.

What do the IP65 and IP67 ratings mean for Murrelektronik M12 junction blocks?

IP65 indicates protection against dust ingress and low-pressure water jets from any direction. IP67 indicates protection against dust ingress and temporary immersion in water up to 1 meter for 30 minutes. In the Murrelektronik M12 range, models such as SKU 852UA4 and SKU 852UG6 are rated IP65, while SKU 852UC6, SKU 852UC7, and SKU 852UE5 are rated IP67. The higher IP67 rating is suitable for applications where washdown or temporary flooding may occur. Both ratings are defined by IEC 60529. Selection should be based on the actual environmental conditions at the installation site.

Can Murrelektronik M12 junction blocks be used without a homerun cable?

Yes, the Murrelektronik M12 junction blocks listed by 3G Electric are passive sensor junction blocks without homerun cable. This means they do not include an integrated cable for connecting to the control system. Instead, the homerun connection is made via a screw terminal cap, such as the 9-pole, 12-pole, 14-pole, or 16-pole caps specified for each model. This design allows the installer to use a custom cable length or to connect directly to a terminal block. It also simplifies replacement because the block can be swapped without rewiring the entire homerun cable. The passive design requires no external power for the block itself.

What are the port and pole configurations available in the Murrelektronik M12 line?

The Murrelektronik M12 passive junction blocks are available with 4 or 8 ports. Port connectors are M12 female, with either 4-pole or 5-pole configurations. For example, SKU 852UA4 has 4 ports with 4-pole connectors. SKU 852UC5, SKU 852UC6, SKU 852UC7, SKU 852UD5, and SKU 852UG6 have 4 or 8 ports with 5-pole connectors. SKU 852UE5 has 8 ports with 4-pole connectors. The pole count must match the sensor cable connectors. 5-pole connectors are often used for sensors with additional functions or for compatibility with both NPN and PNP wiring. Always verify the connector type on the sensor and the junction block.
