IP67 Products with the key figures IP68 are protected against any kind of external touch and the ingress of dust. Moreover it is well protected against the ingress of water even immersed over an unlimited period of time. Needless to say it is also dust and water proof.
IP68 Products with the key figures IP68 are protected against any kind of external touch and the ingress of dust. Moreover it is well protected against the ingress of water even immersed over an unlimited period of time. Needless to say it is also dust and water proof.


 Wipe disinfection  Being considered as a subcategory of the surface disinfection, the cleaning agent is dispersed by wiping on the keyboard or mouse surface. Precise dosage and exposure time are very important (see exposure time VAH-List). The VAH-List is accessible for every user.
Spray disinfection The cleaning agent is sprayed on the surface. Therefore parts of the surface are wet which are not reachable just by surface disinfection. As this method is very quick it is also a useful supplement to normal wipe disinfection. Harming to health, cleaning agents can be inhaled while sprayed. Moreover the surface needs to be wiped after spraying to grant a proper disinfection.
Rinse disinfection The keyboard or mouse is flushed with the cleaning agent and cleaned up mechanically. Coarse dirt gets washed off by the flowing cleaning agent. With the help of a soft cloth or a smooth brush the remaining residues can be removed easily. 
Immersion disinfection Keyboards or mouse are immersed into cleaning agents. Depending to the exposure time the remaining residues are washed down afterwards. Compared with the normal surface disinfection, this method is much more effective but also more time-consuming and expensive.
Autoclaving While autoclaved the keyboards are disinfected under overpressure in a gas tight container. This process removes deep-rooted dirt compared with a normal disinfection but is more time-consuming.
Uperization There are several ways to sterilize the keyboard but basically it effects by using hot steam with up to 125°C. Depending on the method the steam flows around the keyboard with over or negative pressure or as a steam-air mixture. Most germs can be eradicated with this method.


Cross infection Cross-contamination is the direct or indirect, unintentional transfer of germs or infections. Careless cleaning of dishes or clothes as well as washing hands contributes to cross-contamination. If they are not reprocessed properly, PC keyboards are also a good breeding ground. Especially hospitals are highly endangered as many different germs and pathogens come together within a small area.  Comprehensive and proper disinfection measures are of very high priority.
Hospital infection source That is an infection that occurs during a stay in hospital or a care facility. Hardly to prove, hospital infection source is likely passed on to patients by nursing staff or visitors. Unfortunately an increasing number of multi-resistant germs developed during the last years. Those germs cause more serious infections as they are resistant against common disinfection or treatment methods.
VAH List The VAH-List is a list of disinfectant liquids of the German Verbund für Angewandte Hygiene (VAH). The disinfectants and the active ingredients were examined by independent test laboratories and classified as appropriate with regard to chemical disinfection. Above all end users can find all VAH certified products together with the corresponding information and instructions for use.
EN60601-1 EN 60601-1 is a European norm that defines the requirements for electrical systems for the purpose of treatment, diagnosis and monitoring. Also belonging to this norm further standards (collateral standard; particulate standard) must be respected.


 Key travel Key stroke is the displacement distance between the key and the actuation. It is essential to know how far the key needs to be pressed to reach the point of pressure.
 Key Force The pressure point results as soon as an electrical signal is transmitted to the computer. The pressure point makes it perceptible when the computer recognizes key actuation.
Carbon-on-Gold contact Two v-shaped (sometimes prismatic), closely together and crossed contacts are characteristic for the Gold Cross Point Contact System. This configuration grants quicker contacting, reduced abrasion and bouncing and a constantly low contact resistance. This contact system was first patented by Western Electric in 1930.
Scissors balance structure In contrast to common keyboards, Scissor Balancing Key Technology is inserted to reduce the noise emission while operating. Every single key sits on a cross switch. Due to the reduced switch force keyboards with scissor balancing key technology are the best choice in open plan offices.
Key film The metal shrapnel on the conductive film of metal shrapnel is located on the conductive part of PCB (most of them are located above the golden finger on the circuit board). When pressed, the center point of the shrapnel is concave and contacts the circuit on PCB, thus forming a loop. The current passes through and the whole product can work normally.
Conductive film ITO conductive film is a kind of high-tech product which is obtained by magnetron sputtering and high-temperature annealing.
Capacitive screen touch key The capacitive inductive touch button can penetrate the insulating material shell for more than 8mm (glass, plastic, etc.), and accurately detect the effective touch of fingers. And ensure that the sensitivity, stability, reliability of the product will not change due to changes in environmental conditions or long-term use, and has waterproof and strong anti-interference ability, super protection, super temperature range


USB The Universal Serial Bus (USB) is an established connector for external devices, transmitting data files serially. There are many different types of USB devices, which can be used for storing data, power supply or just to connect devices. The data transmission rate ranges from 12 Mbit/s (USB 1.0) to almost 20 Gbit/s (USB 3.2).
PS/2 Developed by IBM the PS/2 interface was often used for connecting keyboard, mouse or trackball to the computer,  Nowadays USB plugs or adapters replaced this interface almost unexceptional.
RF 2.4GHz The USB nano dongle is a small receiver which connects external devices (keyboard, mouse) to the computer by radio technology. Almost unlimited mobility of the external devices is granted as only one USB-port is needed. The dongle transmits data files with 2.4 GHz radio technology.
Bluetooth Bluetooth connections only work over a short distance. Data files are transmitted by Point-to-Point or Point-to-Multi point (WPAN) short-distance radio technology. Interference are more unlikely because of the short distance. The main purpose of Bluetooth is to connect devices without a cable.
RFID RFID, also known as radio frequency identification, is a communication technology, commonly known as electronic tags. It can identify specific targets and read and write relevant data through radio signals without establishing mechanical or optical contact between the identification system and specific targets.
Frequency hopping Transmitted information are spread on several frequencies within short intervals. Among others this technology is used with Bluetooth and WLAN.


TouchPad A TouchPad is a pointing device for the computer which replaces the common mouse. Making it possible to operate just with the keyboard, the TouchPad is integrated into the keyboard. The operation is made by moving the finger over the capacitive area of the TouchPad.
Trackball Trackball is another type of operation navigation key. Its working principle is similar to that of mechanical mouse. It drives the X and Y axis through the roller movement, and sends signals to the corresponding Hall element through the multi pole magnetized magnet fixed on the axis, so as to determine the motion trajectory. The internal structure is similar. The difference is that when the trackball works, the ball is on the top and is directly moved by hand, while the ball seat is fixed. Because it is a non-contact sensing signal, there will be no wear.


Optical engine Optical Mice use a light source that illuminates the surface underneath the mouse. The reflecting light is absorbed by a sensor processing it as images. By calculating the difference between the single pictures the direction and speed of the mouse can be identyfied and put out on the screen. Equipped with more efficient processors modern optical mice are operatable on almost every surface.
Laser engine Laser mice are improved optical mice, as they use laser diodes instead of LEDs. They are based on infrared technology to achieve higher contrasts. Therefore movements of the device can be captured more efficient even on smooth surfaces. Transparent surfaces e.g. glass still cause scan problems though.
DPI The point density indicates the precision with different visual images. The precision of a computer mouse is specified in DPI (Dots per Inch). This means in effect how many dots per inch can be scanned. The higher the DPI, the more sensitive is the mouse. Some mice have adjustable DPI figures. The user is able to configurate individual settings in sensitiveness and precision.
Scroll Sensor Replacing the common scroll wheel the scroll sensor is a capacitive sensor surface like a touchpad. Standard function is up and down scrolling. Some mice have multi functional scroll wheels e.g. as a third mouse button.


Silicone Silicone is a multifarious and universal plastic material, which combines chemical resistance (against a great variety of chemicals with a high temperature resistance) and flexibility (even at low temperatures). As covers for keyboards and mice silicone membranes are used as they are heat resistant and stay elastic. Silicone can be colored by adding pigments. Its chemical features and degrees of hardness can be adjusted depending on the application.
ABS ABS (Acrylonitrile-butadiene-styrene copolymers) is a thermoplastic material. ABS is globally used for household wares, consumer products, foils as well as in the automotive sector and electronic products. The temperature range reaches from -20° to +60°C (storage) resp. 0° to +50°C (operation).
Nano silver Nano-Silver the most successful product within Nano-Technology is antimicrobial. Reducing odours it is inserted in several cleaning and washing agents. Basic components for hygienic or cosmetic products are fortiefied with nano silver particles due to its germ-reducing effects. It has been proven that Nano-Particles harm the environment and humans. Due to their size, Nano-Particles pass through human cell structures and accumulate within the body. The particles kill negative germs as well as the essential. The use of Nano-Silver is controversial. In order to protect the user and the environment, Active Key completely does without Nano-Silver coatings.
Stainless steel New uses are being continuously found for the attractive appearance, corrosion resistance, low maintenance and strength of stainless steel. Stainless steel is more expensive than standard grades of steel but it has greater resistance to corrosion, needs low maintenance and has no need for painting or other protective coatings. These factors mean stainless steel can be more economically viable once service life and life-cycle costs are considered.
