IO-Link guard locking safety switch

07 February 2022

The CTM transponder-coded safety switch from Euchner (UK) features evaluation electronics, a bistable locking function and is capable of the control of guard locking via IO-Link communication means that no separate wiring is needed for the control of guard locking, because the existing communication connection is used. 

The CTM offers detection of 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, 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 
 
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.
 
The compact IO-Link version of the CTM is suitable for safety applications including the protection of personnel and processes.  A hygienic version features only food-safe materials. Featuring a locking force of 1,000N the CTM can be discreetly installed on small, lightweight doors and flaps with a pivoting radius from 150mm.
