INDUSTRIAL SAFETY ADVERTISEMENT FEATURE CTM SAFETY INTERLOCK IS PERFECT FOR THE FOOD INDUSTRY


Euchner has launched a range of compact and highly secure locking switches, with models suited to hygienic applications


T


he 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 number of operations, operating temperature, etc. can be used by the control system to ensure the maximum ‘up-time’ of the equipment. The compact dimensions of the CTM


switch, which is just 120x36x25mm, 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 and flaps to be used where more complex sliding access solutions had to be used previously. 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 and actuator pin. Achieving an ingress rating of IP69K, the switch is completely watertight and can be intensely cleaned or pressure washed without the worry of any damp or water ingress to the unit. The hygienic version is approved to EU Regulation (EC) No 10/2011. David Dearden, Euchner’s UK&I Country


Manager, said: “With all the attributes of the standard version, 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.” 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


The new range of locking switches, from machine safety experts Euchner, features models perfectly suited to hygienic applications in food and beverage plants where cleanliness is critical


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 interlocks feature clear multi-angle


indicators giving ‘at-a-glance’ vision of the switch status.
