A new version of industrial safety engineering specialist Euchner’s CTM transponder-coded safety switch which can be guard locked or unlocked via IO-Link communication promises to future proof the device for Industry 4.0.
The safety switch combined with an IO-Link Gateway can communicate and send process and device data to higher-level control systems. It means no separate wiring is needed for the control of guard locking, because the existing communication connection is used.
“As a safety device, the CTM is smart, compact, safe and features everything you need from a guard locking safety switch,” commented Euchner’s UK&I country manager David Dearden. “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,” he explained.
Evaluation electronics integrated within the CTM allow 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 while maintaining high levels of performance.
In addition, a 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. This function 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 (plus 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.
