Protection of the user in automatic terminals for libraries

The terminal have of blinds that open when the user accesses to them. In this machine looked for a suitable solution that could detect the presence of hands near of the persiana to avoid that this close during the return or withdrawal of the supports. Other requirements included a compact design, a setting and concept of connection that facilitated the integration, high immunity to the environingingmental light and availability of international service. Sick Supplied an ideal solution and, at the same time, did charge of the functions of automation in other parts of the technology of these systems.

To avoid the unforeseen closing of the blinds, integrated cheese cheese photoelectric curtains of compact hygiene (MiniTwin2) of Sick. It treats of sensors with a very small design and a perfect resolution for the protection of the fingers. This means that the photoelectric curtains can integrate without occupying almost space or bother to the user. They install behind the blinds and detect of reliable form even the hands of small boys.

Once the customer has accessed to the terminal, the persiana opens so that the book or support can be given back through the slot. This interrupts miscellaneous do of light, what avoids that the persiana close too prompt. His extraordinary immunity to the light of environingingment warns the false alarms and guarantees the maximum availability. The system of sensors is immune even to the intense solar light. For this reason so much the process of return like the function of monitoring do not see affected and the user does not have to concern that the persiana close too prompt.

Minivation Constitutes an innovation in carcasas miniaturizadas: by first time, the elements emisor and receptor have integrated cheese cheese in a carcasa extremely compact in the photoelectric curtain MiniTwin. The miniaturisation optimises the integration of machines, allows the standardisation to reduce costs and simplifies the manipulation.

His advantages

• Resolution and immunity to the light acclimatise that they guarantee a reliable monitoring of the operation of the persiana
• Design and technology of connector that ensure an integration, put in operation and supply of affordable components
• Support and fast service in situ that optimise the availability of the sensors and the assistance to the final customer
• Solutions of sensors of an only source; also for other tasks

The photoelectric curtain allows to monitor of reliable way the operation of the persiana in the terminal for libraries. The concept of the same reference so much for the emisor and the receptor, together with the use of technology of industrial connection standard, reduces the expenses of acquisition, storage and logistical and of service. The immediate answer to the questions suppose an appeal more. Another advantage is the world-wide presence of Sick. There are available suitable devices almost in any place in some hours, a service that our final customers value especially. This machine also includes other systems of sensors Sick, like sensors inductivos, compact photoelectric sensors, rejillas photoelectric for automation and sensors of wire of optical fibre.
