Euchner’s new compact CTM Safety Interlock is perfect for food, brewing & dairy equipment

06 November 2020

Machinery safety experts, Euchner, have launched a new range of compact and highly secure locking switches with models perfectly suited to hygienic applications in food & beverage plants where cleanliness is critical. 

The interlocks feature high-level coding using transponder technology and an advanced diagnostic capability that provides excellent resistance to misuse, especially where motivation for defeating the safety systems on the equipment is likely. Information, such as actuator tampering, operating temperature, etc. can be used by the control system to ensure the maximum ‘up-time’ of the equipment.

Compact design
The compact dimensions of the CTM interlock, which is just 120 x 36x25mm, makes this one of smallest locking devices of its type. 

The locking ball actuator on an elastomer bearing allows some degree of flexibility which enables the CTM to be used on smaller, lightweight doors with extremely small pivoting radii, right down to 150mm. This allows lower cost swing-type doors & flaps to be used where more complex sliding access solutions had to be used previously. 

Hygienic version for all types of clean environments
Manufactured from strong, food-safe materials, the hygienic CTM is full of features including rounded edges, smooth food-grade surfaces, special FKM elastomer sealing designed to eradicate possible gaps and INOX 316L stainless steel fixings & actuator pin. Achieving an ingress rating of IP69K, the switch is completely watertight and can be intensely pressure cleaned without the worry of any moisture ingress to the unit. The hygienic version is approved to EU Regulation (EC) No 10/2011

David Dearden, Euchner’s UK&I Country Manager, says: “With all the attributes of the standard CTM Interlock, plus additional physical enhancements for ensuring environmental safety, the hygienic switch is specifically designed for use in situations where cleanliness is paramount, including food and drink manufacturing or dairy processing industries for example.” 

Functionality
The bi-stable guard locking function, with a locking force in excess of 1000N, means that in the event of a power failure or shut-down, the switch remains in its current state, the guard door is either locked or it can be opened and closed as required, making it much safer for applications where body access is required or where clean-down or maintenance procedures are ideally carried out without power being applied to the machine.

The CTM features clear multi-angle indicators giving ‘at-a-glance’ vision of the interlock status.
