MURRELEKTRONIK

Murrelektronik GmbH, founded in 1975 in Oppenweiler, Germany, is a manufacturer of industrial connectivity and automation components. The company's product portfolio centers on passive and active connection systems, including cordsets, fieldbus connectors, junction boxes, power supplies, and signal conditioners. Murrelektronik is known for its M12 and M8 circular connectors, which are widely used in sensor/actuator wiring for factory automation, as well as its continuous-flex control cables and motor suppressors. The brand emphasizes robust mechanical design and environmental sealing, with many cordsets rated IP65, IP66K, or IP67, suitable for washdown and harsh industrial environments. Cable jacket materials include PVC for general-purpose flexing, PUR for twisting applications, and TPE for heaviest-duty conditions, covering a range of mechanical stress profiles. Murrelektronik also produces Y-distributors, splitters, and passive distribution boxes that simplify wiring in distributed I/O architectures. Their motor suppressors, such as the RC 3 ST varistor-star type, are designed to reduce electromagnetic interference in motor circuits. 3G Electric stocks over 2,000 Murrelektronik SKUs, including single-ended cordsets, M12-to-M8 adapters, control cables, and suppression modules, with datasheets and logistics support for global procurement. The product line supports applications from simple sensor connection to complex multi-axis machinery, with specifications such as 22 AWG wire, 4 A current ratings, and 300 V voltage limits. Murrelektronik components are designed to meet CE standards and are compatible with common industrial protocols, though the brand does not manufacture active network switches or PLCs. For engineers and maintenance managers, Murrelektronik offers a standardized, modular approach to wiring that reduces installation time and improves reliability in automated systems.

Common Applications

  • Factory automation — M12 single-ended cordsets (e.g., 812PX4) for sensor wiring in conveyor systems
  • Robotic arms — TPE-jacketed cordsets (e.g., 812WF4) for heaviest-duty flexing in pick-and-place cells
  • Distributed I/O — Y-distributor cordsets (e.g., 813EG4) for splitting signals to multiple sensors
  • Motor control — Varistor-star motor suppressors (e.g., 852TZ4) for EMI reduction in AC motor drives
  • Washdown environments — IP66K-rated cordsets (e.g., 812WF4) for food processing equipment
  • Continuous motion — PUR-jacketed control cables (e.g., 813EV4) for cable tracks in packaging machinery

Frequently asked questions

Common questions about MURRELEKTRONIK from 3G Electric.

What IP ratings are available on Murrelektronik cordsets?

Murrelektronik cordsets are commonly rated IP65, IP66K, or IP67, depending on the connector type and cable jacket. IP67 is typical for M12 straight connectors with PUR or PVC jackets, providing protection against temporary immersion. IP66K is found on some TPE-jacketed cordsets and Y-distributors, offering resistance to high-pressure water jets. Always verify the specific SKU datasheet for exact rating.

What cable jacket materials does Murrelektronik offer for flexing applications?

Murrelektronik provides three primary jacket materials: PVC for general flexing applications, PUR for twisting and continuous motion, and TPE for heaviest-duty environments with abrasion or chemical exposure. PVC cordsets are cost-effective for moderate flexing, while PUR offers better resistance to oils and mechanical stress. TPE jackets are used in demanding conditions like robotic arms or drag chains.

Are Murrelektronik cordsets compatible with standard M12 sensors?

Yes, Murrelektronik cordsets use industry-standard M12 and M8 circular connectors per IEC 61076-2-101. They are compatible with sensors, actuators, and fieldbus devices from other manufacturers that follow the same pinout and coding (e.g., A-coded for sensors). Always match the number of pins and gender to your device.

What is the maximum current rating for Murrelektronik M12 cordsets?

Typical Murrelektronik M12 cordsets with 4 pins are rated for 4 A maximum current, while 8-pin versions are rated for 2 A. These ratings depend on wire gauge (e.g., 22 AWG for 4-pin, 19/22 AWG for 8-pin) and ambient temperature. For higher current requirements, consider using larger-gauge cables or alternative connector types.

Does Murrelektronik offer cordsets with integrated status LEDs?

Yes, Murrelektronik produces single-ended cordsets with built-in status LEDs, such as the 812RH1 model. These LEDs indicate power or signal presence at the connector end, aiding in troubleshooting. They are available in M12 right-angle configurations with PVC jackets and IP65 ratings.

What is the voltage rating for Murrelektronik control cables?

Murrelektronik continuous-flexing control cables, like the 813EV4 series, are rated for 300 V. These cables use copper conductors with PUR jackets and are suitable for dynamic applications. For motor suppressors, voltage ranges extend from 400 to 575 V AC, as seen in the RC 3 ST model.
