“We being a machinery safety solution partner, our contribution is not just protection; it is enabling a safer, more connected, and more productive automation strategy”

1. With the rapid adoption of automation and robotics in manufacturing, how are Schmersal’s safety systems and controllers being integrated with robotic cells and automated production lines to ensure safe human–machine collaboration?

In the rapid adoption of automation and robotics in manufacturing, Schmersal safety systems are increasingly being integrated not as an add-on guarding supply, but as part of the overall safety architecture of the robotic cell. In advanced manufacturing environments, key role is to connect safety logic with the robot controller and the wider automation system so that safety becomes an active part of machine behaviour, not just a passive protective layer.

This is an important aspect in applications where people and robots share production space more dynamically. As Schmersal describes its robot-oriented safety control approach as one that helps define safe spaces and safe speeds, supporting coexistence, sequential interaction, and collaborative operating concepts in line with the risk assessment for the application.

What this means for manufacturers is that safety can be engineered into the way the line runs from the outset. Instead of relying only on hard separation, the cell can be designed to respond intelligently to production states, operator intervention, and process conditions while adhering compliance with relevant robot safety standards such as ISO 10218.

In that sense, as Schmersal being machinery safety solution partner, our contribution is not just protection; it is enabling a safer, more connected,
and more productive automation strategy.

2. Schmersal offers a wide range of safety switches, sensors, controllers, and optoelectronic protection devices. How do these technologies work together within automated or robotic environments to safeguard operators and prevent accidents?

Schmersal’s technologies work together in robotic environments as a connected safety chain, not as isolated devices. The principle is straightforward: control access, detect human presence, evaluate risk safely, and allow restart only when the machine is confirmed to be in a safe state.

At the field level, safety switches and RFID interlocks secure doors, gates, and movable guards so hazardous motion is interrupted the moment protected access is opened. Safety light curtains and light grids monitor openings and approach zones, while safety mats detect whether a person is still inside the cell and help prevent unintended restart.

These signals are then processed by the safety logic layer. For standard applications, our recommendations to suggests multifunction safety relay modules, while larger robotic cells and automated lines can be managed through controllers such as the PROTECT PSC1, which supports flexible safety logic, extensive diagnostics, and safety functions up to PL e under ISO 13849-1.

What makes the system effective is the coordination between these devices. If a guard door is opened during intervention, or if someone reaches into a protected area, the controller evaluates the input and triggers the defined safe response before hazardous movement can continue. That layered approach is particularly important in robotics, where access protection, presence detection, stop functions, and restart prevention must work in sequence and without ambiguity.

Schmersal also strengthens safety through diagnostics. Its solutions can pass status and fault information to higher-level control systems, helping maintenance teams find the reason for a stop faster, reduce downtime, and restore production in a controlled and safe manner.

In practical terms, this means safety is not treated as a barrier to automation, but as an engineered part of it. Each switch, sensor, and controller has a distinct role, and together they create a safety architecture that is dependable, transparent, and well suited to high-performance automated manufacturing.

3. As factories move towards Industry 4.0 and smart manufacturing, how is Schmersal harnessing digitalisation, networking, and intelligent safety architectures to enable safer and more efficient automated workplaces for its customers?

The role of machine safety is changing in a very practical way as factories move toward Industry 4.0. In highly automated plants, the challenge is no longer only to stop a hazardous movement; but to make safety status visible, traceable, and easier to manage across, connected production systems in their facilities.

This is where Schmersal’s digitalisation direction becomes relevant. Through Schmersal and tec.nicum services, safety is being treated less as an isolated hardware layer and more as part of a broader digital workflow that includes risk assessment, operational data use, maintenance planning, and controlled intervention procedures.

We developed designated software tool to standardise risk-assessment procedures and the presentation of results across global sites, which is particularly useful for manufacturers trying to support a consistent safety approach across multiple plants or machine platforms. In real terms, which reduces variation in documentation, improves comparability, and makes safety updates easier when lines get modified or expanded in these digital & technology transformations.

The same principle applies on the operational side. IIoT and cloud solutions offered through tec.nicum are intended to capture data from networked devices, sensors, and actuators, and analyse it in real time for condition monitoring, predictive maintenance, KPI evaluation, and energy management. For plant teams, the benefit is straightforward: better visibility of machine condition, earlier detection of developing faults, and more informed maintenance decisions before downtime become critical.

Schmersal’s adoption of IO-Link Safety in our products would add another important layer by enabling standardised, bidirectional safety communication down to field level. This will improve interoperability, speed up diagnostics, and support more flexible safety architectures in automated environments.

Taken together, these developments show how digitalisation is making safety more transparent, more adaptable, and more closely aligned with the realities of smart manufacturing.
