Machine guarding interlock range gets smarter Euchner has added new Modular and Classic variants to its Multifunctional Gate Box (MGB) range, which was created to provide a totally integrated lock and handle solution. The MGB2 Modular and MGB2 Classic offer more variations, additional functions, different networking options and intelligent communication features, including diagnostic data, to help reduce equipment downtime and increase productivity. The MGB2 offers a combination of a safety switch, bolt, escape release and door locking mechanism rolled into one. Some production processes need an integrated emergency stop to safely stop the processes, while others need additional request and acknowledgement buttons fitted directly onto the safety
door. The MGB2 Modular and Classic solutions can be adapted to meet individual requirements for integrated operator controls and indication. MGB2 Modular uses PROFINET PROFIsafe to communicate all the safety, non-safety and diagnostic signals to the main controller. It also includes a built-in web-server to allow straightforward interrogation of the unit without the need for specialist software
or programming knowledge. The locking modules can be equipped with controls such as pushbuttons, selector switches, key-operated rotary switches or emergency stop buttons as needed. Submodules allow up to six different control elements in the locking module, which can be replaced with the minimum of disruption due to their hot-pluggable features. Only one fieldbus module is required for up to six locking modules. Besides fewer devices, the user also requires less on-machine cabling and PLC I/Os. If space is limited, the bus node can be installed remotely in another suitable location. The MGB2 Classic is hard-wired directly to the relevant control system – making it a good solution for non-networked installations.
Multifunctional pressure sensing solution SICK has upgraded its pressure sensor offering with the multifunctional PBS Plus, combining electronic pressure control, measurement and real-time monitoring in one IO-Link enabled device. The sensor is said to combine application versatility and highmachine availability with an improved measurement capability between 0.4 and 1000 bar (gauge pressure).
Its 0.5% accuracy, and a scalable analogue output with 5:1 turn-down ratio, supports the ability to set even small measurement ranges to suit the application. The corrosion-resistant stainlesssteel membrane and IP67 heavy-duty plastic housing make the sensor a good solution for many common process applications, such as measuring system pressure, hydrostatic level measurement
or monitoring cylinder pressure in hydraulic presses. The SICK PBS Plus pressure sensor sends process data via IO-Link to the control as measured values in bar, as well as displaying and transmitting process temperature readings in °C. It records and counts over-pressure events, as well as logging operating hours together with high and low pressures and temperatures.
Ethernet connector offers fast and secure data transmission HARTING is now offering expedient interfaces, in the form of its Han 1A series of miniaturised industrial connectors for Ethernet networks which need to connect sensors, machinery, control systems, computers and data centres. The series features two new inserts to facilitate fast and secure data transmission. A D-coded version

can provide end devices with up to 100 Mbit/ sec Cat 5 Fast Ethernet, facilitating Profinet-based communication. The second, X-coded version can provide end devices with up to 10 Gbit/sec, Cat 6A connections - HighSpeed Ethernet. This performance is required, for example, by applications involving live camera

systems. Both data versions feature complete shielding and are fitted with crimp contacts. The Han 1A series offers compact, lightweight and versatile connectors in a rectangular plastic housing. They are said to be particularly well suited to connecting decentralised devices, promoting modular system design and supporting miniaturisation in machine building automation. They require up to 30% less space by comparison with the next-smallest rectangular connectors in the current HARTING portfolio. Control Engineering UK
