Cost-efficient solutions for Braille displays

The production of high-quality braille readers requires a reliable supplier with long practical experience. The development and production of Piezo technology for Braille displays is one of the oldest core competences of HOERBIGER Motion Control.

Based on proven knowledge and on well-known quality and efficiency, HOERBIGER Motion Control developed a compact and cost-effective Braille cell with Piezo-ceramic bending actuators, mechanics and basic electronic parts (required for connection and control).

The original Braille arrangement of 6 raised dots have been extended to a matrix of 8 pins (4 dots per column) enabling 256 possible combinations in one cell. Our module offers four cells. The 32 pins in a single module allows you to streamline components and production processes — take advantage of this scalable solution for the production of Braille modules for Braille readers, displays and lines:

Engineered and designed for cost efficiency
Time-saving service, dismantling, cleaning
Pins won´t fall out during cell disassembly
