To simplify access control and prevent unintentional machine start up, safety engineering specialist Euchner has released the CKS2 safe key system to the UK market. Designed to make integration into a control system easy, the CKS2 is versatile: it can be used as a safe lockout system, authorisation system or trapped key system. It is available separately or as a submodule for the MGB2 Modular from Euchner, opening up many new applications for this door-locking system.
The CKS2 is a versatile system with integrated FlexFunction technology, suitable for a range of applications in manufacturing, warehousing and procurement. It can be integrated into installations with the highest safety requirements, such as category 4 / PL e according to EN ISO 13849-1.
The device can operate as a safe lockout system, an authorisation assignment for starting installation process sequences, an authorisation sequence for several operators, and a key transfer system. Applications can be defined directly in the control system, offering great flexibility.
“Safety tasks, such as access restriction, safe installation lockout and starting, and selection of the operating mode, play a hugely important role in modern facilities,” said David Dearden, Managing Director of Euchner UK. “Wherever there are dangerous machine movements that must be safely started or stopped, the CKS2 brings many benefits to users, particularly its versatility and ease of use.”
Unlike other technology on the market, the CKS2 has no external evaluation device. All evaluation electronics are embedded in the compact unit, which makes installation simpler while guaranteeing maximum safety via highly coded transponder-based keys. The electronic principle of operation eliminates the need for key exchange boxes and key distribution stations.
Getting started is simple, users define the application during initial set up, select a suitable RFID key to activate the required device functions, and assign parameters. If required, they can assign one key to multiple key adapters.
Once set up, the CKS2 has one job: safely detecting the key. When a key is inserted, the key adapter reads the data and checks for validity — if the key is recognised as valid, the safety outputs switch.
The device can connect to IO-Link via the appropriate Euchner gateway, enabling comprehensive diagnostic and communication functions. For example, this includes identifying which key was used to operate the installation.
When used as a submodule for the MGB2 Modular, the CKS2 submodule can be seamlessly linked via PROFINET/PROFIsafe or EtherCAT/FSoE using the MBM bus module, avoiding complex configuration and key management. This assembly provides an attractive new solution for fully automated logistics or complete turnkey applications. Modular expansion is possible, with thousands of different key codes available, thanks to proven transponder technology and the high coding level.
