Multifunctional Gate Box (MGB) – Guard-Locking Interlock & Safety Door Control
The Euchner Multifunctional Gate Box (MGB) is a sophisticated safety solution designed to integrate guard locking, interlocking, operator commands and escape release in a compact, modular housing. It is more than a simple safety switch — the MGB offers complete protection of machine guards and doors, with Category 4 / PL e performance according to EN ISO 13849-1.
Variants like the MGB2 and MGBS build on this platform, offering enhanced connectivity (for example Ethernet/IP™ in the MGB Ethernet version) and simplified wiring for modern automation systems.
Key functions include robust guard locking with monitored bolt insertion, emergency escape release, selectable operator controls (start/stop, enable), and smart diagnostics via fieldbus integration. The system’s modular design adapts to hinged or sliding doors, left or right installations, with rapid installation and servicing in mind.
Whether used in machine building, packaging lines, robotics islands or automated production cells, the Euchner MGB provides a high-integrity, flexible solution that meets demanding safety requirements while supporting operator efficiency and system uptime.
Transponder-Coded Safety Switches & Key Systems – Guard-Locking, Non-Locking, Electronic-Key & Read Heads
Euchner provides advanced transponder-coded safety switches designed for door and guard monitoring in industrial automation. The versions with guard-locking, such as the CTA/CTP series, combine robust locking force and safe monitoring, achieving Category 4 / PL e in accordance with EN ISO 13849-1. These units support IO-Link gateways and enable diagnostics and Industry 4.0 data integration.
On the other hand, versions without guard-locking — for example the CES series — offer secure coded switching without the mechanical locking element, suitable for applications where guard movement must be detected but locking is not required. By selecting between guard-locking and non-locking variants, users can adapt safety solutions to diverse machine designs and guard types, while maintaining top-level performance and compliance.
The EKS and CKS series offer secure, contactless access control using advanced transponder technology. EKS is the flexible read/write system for electronic access management, user identification, and data transfer (freely programmable), while CKS (incl. CKS2) provides maximum safety (Cat. 4 / PL e) as a tamper-proof lockout, authorization, or key transfer solution. Both are robust (IP67), wear-free, and ideal for industrial environments.
Euchner Magnetically Coded Safety Switches – CMS Series for Compact, Non-Contact Machine Guarding
Euchner’s magnetically coded safety switches (CMS series) are non-contact interlock devices engineered to safeguard machinery, guards, and access doors in demanding industrial environments. Using a coded magnetic actuator, a matched read head, and a separate evaluation unit, CMS ensures secure monitoring of guard positions without mechanical wear, even when precise door alignment is difficult or in hygiene-sensitive applications (e.g. food, packaging).
Thanks to their compact design, high protection rating (e.g. IP67 for actuator/read head), and coded magnetic principle, CMS switches provide a robust, tamper-resistant safety solution — ideal where reliability, cleanliness, and minimal maintenance are essential.
Εlectromechanical Safety Switches – With & Without Guard Locking
Euchner offers electromechanical safety switches, tailored for the protection of machine guard doors and safeguards in industrial automation. The versions with guard locking provide mechanical locking of the guard until hazardous motion is complete, ensuring a higher safety level. The versions without guard locking are designed to monitor door position without locking force, suitable when locking is not required or allowed.
Both options support installation in metal or plastic housings, offer multiple actuation types, and accommodate cable or plug-in connectors to match varied machine designs. The selection between locking and non-locking ensures flexible compliance with safety standards while aligning the solution to specific machine requirements and guard configurations.
ESM Safety Relays – Reliable Safety Control with MSC Systems & Filter Module
The Euchner ESM Safety Relays are at the core of reliable machine safety, offering proven Category 4 / Performance Level e protection according to EN ISO 13849-1. Designed for maximum flexibility, the ESM series features compact DIN-rail modules with redundant contacts, cross-fault monitoring, and expandable inputs and outputs, ideal for emergency stops, guard monitoring, and enabling circuits.
Each relay offers diagnostic LEDs, removable terminals, and various control logic options, allowing integration into both new and existing safety architectures.
In addition, the MSC control systems provide a modular alternative with programmable safety logic, making them suitable for complex installations requiring centralized safety management.
The AC-FM-AR filter module complements these systems by suppressing OSSD test pulses from safety sensors, ensuring smooth operation and compatibility with all Euchner safety devices.
Together, these products form a complete safety ecosystem — delivering dependable control, fast installation, and full compliance with the latest safety standards.
Emergency Stop Devices – Rugged E-Stop Buttons & Rope-Pull Switches
Euchner provides a comprehensive range of emergency stop devices, designed to ensure rapid shutdown of machinery and safeguard personnel in hazardous situations. The ES series emergency stop buttons feature a red mushroom head with yellow base, contact block monitoring and reset options by turning or pulling, meeting standards such as EN ISO 13850.
For applications covering large hazard zones where a conventional button may not suffice, the RPS rope-pull switches and RPS-C compact rope-pull models enable triggering from any point along the safety rope. They provide immediate shutdown across extended areas and include tension indicators and detent mechanisms.
Together, these devices offer flexible protection strategies – from targeted operator panels to full-scale machine guarding – helping integrators and machine builders meet stringent safety requirements and maintain compliance.
