InnoSenT, Donnersdorf, Germany, introduced the IMD-3000 radar system as an alternative to pushbutton switches.

The system enables machines, doors, and other devices to be controlled without contact. It is used as a proximity device to reduce exposure to pathogens and dirt. The system is not adversely impacted by lighting conditions, extreme temperatures, or harsh weather conditions and the radar penetrates plastics. The contactless operating principle is based on electromagnetic microwaves emitted by the system’s radar antenna. If the microwaves hit an object, it reflects the signal. The reflected wave is received and assessed by the sensor and the radar determines whether there are objects within its detection range. The system is a direct drop-in replacement for a conventional, mechanical switch and can be connected using an industry-standard JST plug. It is equipped with intelligent signal processing.
