The innovative backlighting system for membrane keypads
By using our innovative NLF technology, almost all backlighting needs can be implemented in a sturdy, compact and cost-efficient way, from a single key to a large area.
- Even light distribution
- Thanks to the use of side LEDs, no expensive and EMC-ESD problematic converters / inverters are necessary for triggering.
- The LEDs can be operated with low DC voltage without any additional complex circuitry – even with battery operation
- LEDs have a long operating life
- > 500,000 cycles acc. to DIN 42115
- Suitable for use in applications with permanent keypad illumination
- Almost all backlighting requirements can be implemented in a compact and cost-effective way
- Both single keys and large areas can be backlit (including individually, i.e. separately from each other)
Field of application
- Wherever the keypad is also to be operated under dark ambient conditions
- As an alternative to the well-known EL membrane
- Not as an alternative to Profiline back-lit,because thanks to the high embossing, this technology has an improved tactile action point
