Modular Blackboard Door Reader

CREATIVE AND MODULAR DESIGN The idea behind this design is to provide a modular solution that can simultaneously be as compact as possible, besides meeting the requirements imposed. The design comes in two flavors: a COMPACT MODEL and a COMPLETE MODEL (with magnetic card reader). The body of the device consists of two parts: the first consisting of the wall bracket; and the second corresponding to the device´s body, where the electronic components (circuit board, contactless antenna, speaker), the keyboard and the LED display are housed. Once the two sides have been coupled by the recommended screws, an aluminum housing that covers the entire device is used. The housing is subdivided into two parts, which are introduced from the top and bottom part respectively, sliding through the grooves made in the body. First the upper housing slides down, fixing it from both sides by screws. Then it slides up the lower housing, which cover the screws of the upper housing by a tab, obtaining a hermetic design. Finally, the lower housing is secured from below by 3 countersunk screws, preferably with TORX head. In case of using the complete model with magnetic card reader, a USB adapter should be placed in the specific slot located on the right side of the body, which could be coupled directly to the board or by another data bus. The body of the card reader is also divided in two parts and requires a modified housing. The upper part contains the magnetic card reader and the USB connection, and the lower part acts only as a continuation of the card slot. ----- DON’T FORGET TO CHECK THE ASSEMBLY DRAWINGS IN .PDF FORMAT ----- FEATURES - Slightly inclined screen for easy reading. - Antenna on the left side to take contactless credentials. - LED backlit keypad with brail overlay.
