Murrelektronik makes motor connectivity easyMurrelektronik’s Graham Traill reveals the advantages of the company’s new Motor Connector range. He says: “Murrelektronik’s expansion into motor connectivity is offering huge advantages compared to existing methods. Primarily, the three new product lines are compact and easy to use. They are already proving to be the best on the market and have demonstrated that we are listening to the needs of our customers when developing new products. We are already seeing a vast amount of interest from customers involved in machine building and materials handling. Interesting projects include connectivity to asynchronous motors, servo motors and stepper motors.”

Murrelektronik’s MQ15-X-Power range is a low-cost way to provide connectivity to asynchronous and three phase electric motors up to 7.5Kw. The new M15 connection technology of the MQ15-X-Power offers quick and easy motor connectivity with reverse polarity protection for asynchronous motors up to 7.5kW. The connector has three power contacts rated at 630V AC/DC up to 16A, PE and two auxiliary contacts 63V AC/DC up to 10A. Over-moulded plugs ensure the connector is sealed to IP67 (when mated) and eliminates the risk of wiring errors. In addition, the MQ15 X Power range includes M20 bulk head connectors, meaning connectors can be simply mounted on the motor terminal box (often using the knockout provided by the motor manufacturer) and tightened down using the back nut provided. MQ15 X Power is suitable for applications where quick and easy disconnection and re-connection of motors is required.

The M23-Drive range offers the most powerful 8 pole M23 connector currently on the market. With 630V AC/DC, 28A per pin for the power contacts and 300V AC/DC 8A for the signal contacts, the connectors are suitable for high-performance drives and servo motors. The 360 degree shielding ensures for very low interference emissions. The M23 connector features a high-quality locking mechanism that ensures sealed connections even when exposed to oils and lubricants. The hexagonal locking nut can be tightened to the correct torque using the Murrelektronik torque wrench and a coding arrow on the housing offers a practical installation aid. Flexible corrugated conduit for cable protection can be anchored to the connector by the integrated push-on conduit connection. High-quality, original Siemens cables are an additional strong point of Murrelektronik’s M23-Drive connectivity range.

Completing the range, Murrelektronik’s M12 power connector is described as the most compact and powerful 5 pole M12 connector on the market. The compact design of the L-coded M12 Power connector together with a rating of 63V AC/DC, 16A per contact makes it suitable for applications where a high current and low voltage is required, such as linear drives, brushless DC or stepper motors. The 5-core PUR cable has a wire cross-section of 1.5mm². Flexible corrugated conduit for cable protection can be anchored at the connecter by means of the integrated push-on conduit connection.

The Murrelektronik M12 Power product range includes M12 Power connectors to open ended wires, connection cables with M12 Power male and female connectors, bulkhead connectors and adapters – offering a large number of installation options.
