Developed on the basis of patented optical new technology, the switch without D42 contact combines optical detection with the dynamic analysis of the signal and a function of car-calibration to produce a sure, precise and reliable switch.

D42 has a very high lifespan and resists freezing. Its plastic case without any zone of retention facilitates its cleaning and makes it possible to be used in demanding environments in terms of hygiene. Its sealing IP68 gives to D42 particularly reliable performances in wet environment.

Built around a microcontrolor, this optical switch is a programmable multifunction button. Its 4 LED controlled by 4 external wire make D42 easy to locate and offer multiple options of luminous feedbacks. The integrated microcontrolor allows APEM to satisfy all the requests customer (increase in the distance from detection, duration of the exit, play of light,...).

Functionalities:
- Button without contact
- Button broad and enlightened for easy localization
- Luminous Feedback with various combinations of play of light
- Multifunction Button easy to personalize
- High immunity EMC
- IP68, reliable operation in wet environment

Applications:
- Applications where hygiene is critical (agribusiness industry, medical equipment,...)
- External and public Equipment (control systems of access, kiosk of information,...)
- Watery Equipment (swimming pools, spa,...) and very wet environments
- When the use of only one multifunction button is advantageous (space saver, programmed succession of actions)
- Applications with use of gloves
