Industrial safety engineering specialist Euchner will use its stand at this year’s PPMA exhibition to launch two new and exciting products – the Industry 4.0 Ready CTS safety switch and CKS2 coded key system – and showcase its extensive range of guard locking products available for common fieldbus connections.

The all-new, one-fits-all CTS is Euchner’s first FlexFunction device and expands the company’s product range by sitting between the all-round CTP and specialist CTM safety switch solutions, by combining the best of both worlds in a single switch while offering maximum flexibility. A key innovation of the compact CTS – which is IO-Link compatible and Industry 4.0 ready – is the company’s new FlexFunction feature that, by using the transponder-coded actuator to determine the switch’s function, allows a single device to perform a wide variety of functions that would otherwise require several switch variants. Its compact dimensions, high locking force of 3,900N and suitability to mount in three orientations ensures the CTS is suitable for use across numerous safety engineering applications.

Combined with highly-coded, transponder-based keys, the new CKS2 from Euchner forms a safe system that meets the highest safety requirements for machine and installation lockout and starting. Thanks to the integrated evaluation electronics and depending on the key used, various safety engineering tasks are possible with the compact CKS2 key system. Additionally, combining it with Euchner’s IO-Link Gateways expands its applications and enables comprehensive diagnostic and communication functions. 

Unlike the CKS, the CKS2 can be integrated as a module within Euchner’s Multifunction Gate Box MGB2, expanding the functionality of the simple door interlocking solution to a small control terminal with access control.

Commenting, Euchner’s UK&I Country Manager David Dearden says: “The combination of MGB2 and CKS2 can be used across multiple sectors and for numerous applications to ensure process efficiency, create access rights flexibility, increase personnel and process safety, safeguard product quality and create transparency and traceability.”

The MGB2 is a unique interlocking or guard locking system for the protection of safety doors on machines and systems that, thanks to its modular approach, is more than simply a safety switch or bolt and offers a vast array of safety functionality. By incorporating additional safety modules to the MGB2, machine builders can include numerous functions, including guard locking, escape release, start/stop, emergency stop, etc. Its modular design also means the MGB2 can remove the additional need for a separate operator panel. And with networking opportunities available, it also reduces wiring and installation time. 

The MGB2, CKS2 and CTS are just three examples of the safety devices available from Euchner. For further information on these and other machinery safety solutions, the company’s technical and product support team will be on stand E68 at PPMA 2022 from 27th to 29th September.

The CTM transponder-coded safety switch from industrial safety engineering specialist Euchner (UK) Limited features evaluation electronics, a bistable locking function and is capable of the control of guard locking via IO-Link communication, future-proofing the device for Industry 4.0 and meaning no separate wiring is needed for the control of guard locking, because the existing communication connection is used.

Commenting, Euchner’s UK&I Country Manager David Dearden says: “As a safety device, the CTM is smart, compact, safe and features everything you need from a guard locking safety switch. However, the IO-Link version brings further benefits to the CTM range by adding the ability to lock and unlock the device over IO-Link communications, coupled with the comprehensive diagnostic data provided by the IO-Link protocol.” 

The evaluation electronics integrated within the CTM allows for simpler wiring and a greater level of detection for connection faults, short-circuits and errors. Additionally, it allows the guard locking safety switch to be wired separately or in series whilst maintaining high levels of performance, up to and including Category 4/PLe according to BS EN ISO 13849-1 and BS EN ISO 14119, ensuring the highest safety level category despite the CTM’s compact size.

The bistable locking function can prevent the deactivation of the activated guard locking in case of a power failure, ensuring that guard locking remains in its current state if the power fails or the installation is switched off. It can also prevent personnel from unintentionally locking themselves inside a potentially unsafe area if the safety door is open in the case of power failure or if the machine is switched off, meaning no additional escape release is required.

The highly compact IO-Link version of the CTM is suitable for numerous safety applications including the protection of personnel and processes, with a hygienic version consisting exclusively of food-safe materials also available for the packaging and food sectors. Featuring a locking force of 1,000N (and integral adhesive force of 25/50N) and an innovative safety ball actuator, the CTM is ideal for discreet installation on small, lightweight doors and flaps with a pivoting radius from 150mm.
