Schmersal Ibérica, S.L. - Security locks

Schmersal Commercialises a switch selector of electronic key based in the technology RFID for the identification of pieces, units of packaging and products. A system of identification without contact of components that offers, besides, some advantages in hygiene.

This selector of key allows a safe disconnection of the automatic way of a machine, by means of the contact NC of positive split with conventional methods, to commutate later the control of the device to different ways of operation. This achieves through an operation “and” that establishes between the usually open contact electromechanical and the signal of the transponder RFID integrated cheese cheese in the key. The system comes preprogramado of factory with until three different levels of permission.

The three keys, with individual and different coding codes of colour, distribute to the users of the machinery depending on his level of permission. Of this form the operator can, for example, initiate the way of configuration to speed reduced by means of an enabling switch when the door of hygiene is opened, whereas the attendant is authorised to activate the way of control of process, a way of special operation that generally requires a greater speed of process. Besides, they exist other levels of permission.

The selector of key presents, in addition to the contacts NC/NA traditional, contacts of additional relay for the codings RFID. The logical combination of these signals achieves by means of the part of the control of the relative machinery to the hygiene.
