Euchner CTM transponder-coded door lock

The space available for safety engineering and the time allotted to wiring equipment as diverse as machine tools, packaging machines and food production systems are steadily decreasing. Due to its compact dimensions, the Euchner CTM transponder-coded door locking mechanism is particularly simple to integrate into the machine design. The ball actuator supported on an elastomer bearing can secure doors with extremely small pivoting radii. This type of guard locking offers maximum flexibility to the design engineer.

The bistable guard locking function of the CTM safety switch ensures that guard locking remains in its momentary state if the power fails or the installation is switched off. In other words: a locked door will stay locked if it was locked before, or it can be opened and closed as needed if guard locking was not previously activated. People can therefore no longer be locked in unintentionally if the power should fail.

The CTM’s intelligent communication capabilities futureproof it for Industry 4.0. It can simply be connected in series with other Euchner devices, for example. The integrated interface additionally permits connection to the Euchner ESM-CB evaluation unit, which then forwards the data via IO-Link to the higher-level control system.

Euchner has complemented the standard CTM with a hygienic version for use in the food industry. This version consists exclusively of food-safe materials; all plastics are approved according to EU Regulation (EC) No. 10/2011, for example. This version features smooth surfaces, rounded edges and materials resistant to cleaning agents.
