Devices must also be installed according to their certified application instructions. ## **Which Major Brands Offer Industrial Safety Products?** ### **1. EUCHNER Safety Products** EUCHNER has a strong machine-safety portfolio focused particularly on safety switches, guard locking, transponder-coded systems, and safety evaluation devices. The CES series includes non-contact transponder-coded safety switches for monitoring machine guards. For example, the CES-BP provides two safety outputs that can connect to drives, safety relays, or safe control systems. EUCHNER also offers ESM safety relays and evaluation units for processing safety signals. Its ESM-CB devices can monitor safety-related signaling devices and control safety actuators. **EUCHNER products to consider:** - CES transponder-coded safety switches - CTP guard-locking safety switches - ESM safety relays - AR safety evaluation units - Guard-locking and access-control systems EUCHNER is particularly useful where machine doors, movable guards, and controlled access points require dependable monitoring. ### **2. OMRON Safety Products** OMRON offers one of the broader machine-safety ranges, covering safety controllers, relays, switches, light curtains, and other presence-sensing devices. The G9SA Safety Relay Unit supports common safety devices, including safety light curtains and two-hand control applications. It provides a traditional relay-based option for machines requiring dedicated safety functions. For presence detection, OMRON offers the F3SG safety light curtain range for finger, arm, body, and perimeter protection applications. OMRON also supplies programmable safety controllers for machines requiring more flexible safety logic than a conventional relay. **OMRON products to consider:** - G9SA safety relay units - G9SP safety controllers - F3SG safety light curtains - Safety door switches - Safety controllers and I/O systems Simply Buy currently lists the G9SP Series Safety Controllers within its industrial safety relay and controller catalog. ### **3. Allen-Bradley Safety Products** [Allen-Bradley](https://www.simplybuyglobal.com/wp-content/uploads/wp-mfa-exports/post/rockwell-allen-bradley-products-pros-cons-pricing.md), a Rockwell Automation brand, provides a broad machine-safety portfolio covering sensing, logic, control, networking, and final switching devices. The 440R Guardmaster family provides safety relays for functions such as emergency stops, guard monitoring, and presence-sensing applications. For larger automation systems, GuardLogix and Compact GuardLogix controllers combine standard machine control with programmable safety functions. Rockwell also documents GuardLogix architectures for E-stops, interlocking, light curtains, scanners, and safe-speed applications. The 450L GuardShield series provides safety light curtains for point-of-operation protection. The range includes basic and advanced configurations for different machine requirements. **Allen-Bradley products to consider:** - 440R Guardmaster safety relays - GuardLogix safety controllers - Compact GuardLogix controllers - Guardmaster safety switches - 450L GuardShield safety light curtains - POINT Guard safety I/O This range is particularly useful when safety must integrate closely with a larger Rockwell Automation control system. ### **4. Schneider Electric Safety Products** Schneider Electric supplies machine-safety components through several automation product families, including Harmony Safety and Modicon safety control products. The Harmony XPS range includes safety modules intended for monitoring individual machine safety functions. Simply Buy currently lists Harmony XPS safety modules from Schneider Electric. For applications requiring greater flexibility, Schneider’s Modicon MCM safety controllers support multiple safety inputs and expansion modules. Available functions include switch monitoring, light-curtain muting, and other machine-safety tasks. Schneider also identifies safety interlocks, emergency-stop devices, and light curtains among the technologies used within machine-safety systems. **Schneider Electric products to consider:** - Harmony XPS safety modules - Modicon MCM safety controllers - [Safety I/O modules](https://www.simplybuyglobal.com/wp-content/uploads/wp-mfa-exports/post/what-is-remote-io-module.md) - Safety switches and interlocks - Safety light curtains The choice between an XPS relay-type solution and a programmable controller depends largely on machine complexity. ### **5. Phoenix Contact Safety Products** Phoenix Contact provides safety technology particularly suited to control cabinets, safety relays, and configurable machine-safety systems. Its PSR safety relay families monitor safety functions ranging from emergency stops to safety-door monitoring. Phoenix Contact offers both compact relay modules and more flexible multifunction safety devices. For example, selected PSR safety relays support emergency stops, safety doors, and light grids with one-channel or two-channel operation. For machines requiring more logic, the PSR-TRISAFE safety controller sits between basic relay control and more complex safety PLC architectures. It can handle multiple safety functions within one configurable system. **Phoenix Contact products to consider:** - PSR safety relays - Multifunction safety modules - PSR-TRISAFE safety controllers - Machine-safety monitoring components These products suit panel builders requiring modular safety control alongside other cabinet automation components. ![Modular Cabinet Safety](https://www.simplybuyglobal.com/wp-content/uploads/2026/08/image1-4.webp) ## **How Do These Safety Brands Compare?** | **Brand** | **Safety Switches** | **Safety Relays / Controllers** | **Safety PLC / Programmable Safety** | **Light Curtains / Presence Safety** | | --- | --- | --- | --- | --- | | **EUCHNER** | Strong | Yes | Safety evaluation/control systems | Focus mainly on guarding systems | | **OMRON** | Yes | Strong | Yes | Strong | | **Allen-Bradley** | Strong | Strong | GuardLogix | Strong | | **Schneider Electric** | Yes | Harmony XPS | Modicon safety control | Yes | | **Phoenix Contact** | Safety monitoring solutions | Strong | Configurable safety controllers | Interfaces with safety sensors | The best brand depends on the existing automation platform and the safety function being designed. For example, an Allen-Bradley machine may benefit from GuardLogix integration. A standalone guarded machine may need only a EUCHNER switch and suitable safety relay. ## **How Should You Choose a Machine Safety Device?** Start with the required safety function rather than selecting a product based only on brand. ### **Check the Hazard** Determine what must trigger the safe state. Examples include opening a door, entering a hazardous area, or pressing an emergency stop. ### **Determine the Required Safety Performance** The machine risk assessment establishes the required safety performance. ISO 13849-1 uses Performance Levels, while IEC 62061 provides another framework for machinery functional safety. The final achieved level depends on the complete safety function rather than one individual component. ### **Choose the Correct Safety Logic** A simple machine with one emergency stop may only require a dedicated safety relay. Machines with several guards, light curtains, operating modes, and safety zones may benefit from a configurable controller or safety PLC. ### **Check System Compatibility** Confirm input type, output requirements, supply voltage, communications, reset functions, diagnostics, and compatibility with existing automation hardware. Always follow the manufacturer’s certified connection diagrams when designing and commissioning safety circuits. ## **Safety Relay, Safety Controller, or Safety PLC?** The three devices serve different levels of machine complexity. | **Device** | **Best Fit** | | --- | --- | | **Safety Relay** | One or several straightforward safety functions | | **Configurable Safety Controller** | Several interconnected safety devices and zones | | **Safety PLC** | Complex machines requiring extensive programmable safety logic | A safety relay remains useful for straightforward emergency-stop or guard circuits. A programmable safety platform becomes more practical as the number of devices and safety functions increases. For example, Rockwell documents safety architectures combining GuardLogix controllers with E-stops, interlocks, light curtains, scanners, and safety I/O. ## **Where Can You Source Industrial Safety Products?** [Simply Buy](https://www.simplybuyglobal.com/) sources industrial automation products from major global manufacturers and currently lists safety products including Schneider Electric Harmony XPS and [OMRON](https://www.simplybuyglobal.com/wp-content/uploads/wp-mfa-exports/post/omron-plc-troubleshooting-guide.md) G9SP Series Safety Controllers.
