Textured film protects membrane keypad
MacDermid Autotype
Autotex
Autotex textured polyester film offers proven durability under mechanical load, resistance to cleaning agents and scratch resistance.
Autotex textured polyester film from MacDermid Autotyp is being used to form a key component in membrane keypads made by Hoffmann + Krippner.
The backlit keypads are installed in the Rotalign Ultra laser-optical precision alignment system developed by Pruftechnik Alignment Systems.
Surveys have shown that around half of all failures in industrial machinery are due to incorrect alignment of motors, gearboxes and drive shafts.
The Rotalign Ultra addresses this problem, making it simple for engineers to set up machinery with absolute precision, with the specially developed keypad providing an intuitive method of system control.
Pruftechnik had stringent requirements for the control unit.
The alphanumeric keypad has to be able to function reliably at all times and also be backlit, dust-proof and splash-proof to IP65 and be equipped with LEDs.
Wolfgang Beckert, Sales Manager at Hoffmann + Krippner said "The backlit keypad was designed according to ergonomic criteria and has three types of keys: navigation, data entry and function keys".
"We used Autotex from MacDermid Autotype for the membrane graphics and switch layers".
The polyester film offered proven durability under mechanical load, resistance to cleaning agents, scratch resistance and had an attractive appearance.
