The new RAFIX FS emergency stop switch from Rafi has a mounting depth of only 9,7 mm, which makes it suitable for combinations with short-travel keys on the same PCB. In contrast with arrangements using conventional emergency stop switches the depth behind panel of the complete system can be drastically reduced.
The new Rafi emergency stop switch consists of an actuator and a contact block. The actuator is fastened in the front panel using a ring nut - panel cut-out 22,3 mm - making it water-jet proof (IP65). The contact block is soldered on to the same PCB which also accommodates the short-travel keys, LEDs and displays of the keyboard. The PCB is mounted to the front panel with bolts. The advantage is that the PCB does not require a cut-out for the emergency stop switch, the separate emergency stop connection is eliminated and the overall system is very flat. The contact system provides two NC gold contacts for low voltages (100 mA/42 V max) or silver contacts for mains voltage (5 A/250 V max).

Strategic approaches to legacy software in manufacturing
Editor's Choice IT in Manufacturing
One of the most critical and strategic roles of the CIO (or IT Manager) is to ensure that the business’ information systems and tools are well maintained and up to date. If a critical system fails, the business could come to a standstill, forcing people to scramble and revert to paper-based or backup systems. Even worse, production may stop, impacting the entire supply chain and all of your stakeholders.

Users in the process industry have not prioritised cyber security. This might be because they assume the IT department’s responsibility, or they don’t feel directly threatened. However, both attitudes are neglectful, and here’s why: IT security should always be a joint task between IT and OT.

Five steel producers taking action to decarbonise steel production
Editor's Choice IT in Manufacturing
Steel is crucial for engineering, construction and the energy transition. There is rising demand, but it produces 7% of global greenhouse gas (GHG) emissions. However, by 2030, near-zero emission steel at scale can be achieved by using ambitious, innovative technologies, and collaboration between steel purchasers, producers and companies providing enabling technologies.

Edge computing: Introducing AI into the factory
Editor's Choice IT in Manufacturing
As AI evolves, it is evident that the most powerful models will be cloud-based, and hosted in data centres that are beyond the control of the average business. The practical application of AI in manufacturing control and automation will only be possible if some of the computing workloads can be brought onto the plant, inside the firewall and inside the plant network.

AI in manufacturing: a process engineer’s perspective
Editor's Choice IT in Manufacturing
The expert will tell you what to do, the philosopher will tell you why to do it, and the engineer will get on and actually do it. As the hype around AI intensifies, the number of ‘experts’ is increasing exponentially. In contrast, the number of engineers who actually know how to implement AI technology remains small.

Navigating disruption in manufacturing
Editor's Choice IT in Manufacturing
When considering IT in manufacturing, the underlying assumption is twofold: first, a wave of valuable maturing technologies can be harnessed to create new business value, and second, the environment in which these technologies will be applied will be relatively predictable, with change following a manageable, evolutionary path. However, recent disruptions have shattered these assumptions.
