The new LUMINEQ touch technology has been engineered to work even in the heaviest rain and in extreme temperatures. The touch function can be tuned to work on both sides of the glass surface, or just one, based on the application requirements.
LUMINEQ has tested the new water-resistant touch technology worldwide together with world-known brands. Ongoing projects include opening train and bus passenger doors, a keypad standing in the rain for locked containers, and many more for transportation applications.
