plug-And-plAy energy chAins cAn speed up mAchine Assembly time


Readychain speed from igus is a plug-and-play energy chain system that allows connection of fully assembled e-chain systems in seconds, with no tools needed. According to the company, with the readychain speed, users can save 80% machine assembly time; and the e-chain system can also be easily and quickly replaced if cables fail. In addition, with the new


readychain micro-speed, igus has expanded its portfolio of quickly pluggable energy chains into small applications. At just 20mm in width and height, the system is well-suited to applications with very little space, such as door locks in machine tools. It is not necessary to separate the wires from terminal blocks using tools before changing a cable, because the plugs are integrated into the energy chain and the cable is fully connected on both sides. The counterpart, an attachment housing with socket, can be fitted to the machine housing. If a cable change is now required, the plug-in system can be replaced as quickly as the power cord of a laptop. The readychain micro-speed gives customers an interface solution tailored precisely


to their application. According to the company, this is almost infinitely configurable and, like the larger readychain speed, can be combined with cables from igus' wide range of chainflex cables – including power, bus, Ethernet and fibre optic versions. The cables are protected against mechanical damage by the e-chain.


igus www.igus.co.uk new 7in touchscreen hmi


New from IDEC is the HG2J Series 7in touchscreen HMI. Its projected capacitive touch panel (PCAP) technology saves space, improves performance, is wear-resistant, and provides a long life. With a TFT LCD display resolution of 800 x 480 pixels, the


HG2J HMI is suitable for small and large applications, and it provides smooth font rendering within its large high-visibility display area. The overall HMI depth is just 30mm. Operation with an input voltage of 12-24V DC makes the


HG2J HMI suitable for a wide variety of industrial, solar, and vehicle applications. Additional features include a wide temperature range of -20 to +60˚C; IP66/67, UL, and CE ratings, with a Class I Div 2 hazardous location rating; and a full complement of connectivity options. A single reset button is used for rebooting the unit, and


a multifunction front LED light provides status information for the hardware, boot mode, and OS operating mode. Maintenance is simplified because the HMI requires no batteries. The HG2J HMI also supports over 100 serial and Ethernet industrial communication protocols.


iDec A modulAr solution for power And communicAtion


New from Beckhoff is the MX-System, a holistic, modular solution that supplies electrical power and EtherCAT communication from a slim baseplate to plug-in modules that connect directly to nearby systems. This minimises the need for large electrical control cabinets and can allow engineers to entirely substitute conventional control panels. With its plug- in approach, the system can be placed directly by the machine, and modular elements allow operators to adapt the system for their own needs. The baseplate for the MX-System can contain up


to three rows, with a maximum of 24 slots per row. These slots can distribute different voltages and communicate between the slots using the EtherCAT bus, allowing the system to be easily adjusted to equipment requirements. Each module connected to the baseplate is treated as a separate EtherCAT


device, which means comprehensive diagnostics are available for the whole system. The MX-System’s power feed modules each have


their own fuse, which can be replaced when the system is in a de-energised state. To reach this state, the power supply modules have a load-break switch as a main switch, so that the MX-System can also be de-energised under load, which makes the system safe to maintain. The power supply modules are available in different sizes for 16A, 32A or 63A. The mains voltage and the DC link voltage is distributed over the entire power backplane. The outgoing connectors of the respective MX slots can supply the plugged-in modules with both voltages and are loadable with up to 35A, and the entire backplane can be loaded with up to 63A. Furthermore, the 400V AC and the 600V AC


non-contact safety switches


Robust and easy to integrate, norelem’s non-contact safety switches improve safety for operators of machine tools and production lines. Designed for use


on protective covers – including doors, flaps and hoods – the switches ensure equipment can be operated only when all covers are closed. Should a cover be opened during

operation, the switch will automatically shut down. These are available as either magnetically coded


or RFID coded variants, and can be retrofitted to machinery to improve overall safety. With an actuator located on the moving part and the device’s read head mounted on the fixed part, no contact is required for successful operation. norelem’s magnetically coded safety switch


is designed to work effectively over a high switching distance. As activation can only occur with a suitable actuator, the magnetic system is also able to protect against manipulation. Alternatively, the RFID system allows up to 31

voltages can be fed out of the MX-System with power feeder modules and be fed into other MX baseplate stations. The MX-System is equipped with EtherCAT. The


consistent use of EtherCAT also allows TwinSAFE to be used with each module, which increases the safety features of the device.

sensors to be added in a series, making it possible to monitor several protective doors at once. This flexibility is achieved through universal coding, in which every suitable actuator is recognised by the safety switch. Where protective covers need to be monitored independently, individual coding can assign actuators to their own safety switch. Ensuring their suitability for manufacturing


environments, both systems meet IP67 standards for protection against dust and water, in addition to the requirements for ISO 13849-1 and IEC 60947-5-3. The RFID coded variant also adheres to EN62061 and IEC 61508 standards.
