Sealed keyboard is vandal-proof
Diamond Electronics has introduced the Baran KB5000 keyboard, for use in applications that demand reliable data entry under the harshest of environmental conditions.
Diamond takes on force sensing products for PCs
Under a new distribution agreement, Diamond Electronics is to distribute InControl Solutions' products in the UK including the the Button Mouse PCB, MediaPoint and other force sensor products
An extremely rugged alternative to a conventional mouse, mouse pad or trackball, the Eyeball takes the form of a transparent panel set into the surface of the keyboard.
The user operates the device in a similar manner to a mouse pad, by moving his or her finger - which may be gloved - over the surface of the panel.
Finger movement is tracked through the glass panel by an optical detector.

Add a pointing module quickly and inexpensively
Diamond Electronics is offering the new In Control Solutions MediaPoint Plus, a USB and PS2 ready pointing module for integration into PC's, keyboards, and a wide range of electronics
The device converts finger position and direction of movement into X/Y co-ordinates, which are made available to a computer through a conventional mouse driver interface.
This construction allows the device to be completely sealed and very robust, much more so than the relatively fragile surface of a resistive touch sensitive "mouse-pad" detector.
This level of ruggedness matches the performance of the rest of the keyboard, which is built using Baran's patented piezo switch technology.
In place of standard key switches, the keyboard uses switches based on a ceramic element with no moving parts, resulting in extremely high reliability and long life.
The piezo-electric switches detect finger pressure alone as a keystroke, allowing the sealed unit to be designed without provision for mechanical key travel.
The result is a keyboard that combines sensitivity to finger pressure with the ability to withstand significant pressure and impact.
Use of the Eyeball pointing device and the piezo-electric switches allows the unit to be completely environmentally sealed to IP68, barring the ingress of water, oil, salt, dust, grit or any other contaminants.
The keyboard is also rated for use across a wide temperature range.
The KB 5000P is therefore ideally suited to data entry and machine control applications in the most demanding of industrial environments, and it can be rigorously cleaned for use in situations that demand a high level of hygiene.
The KB 5000P follows a standard 103-key standard layout (the suffix "P" indicates the inclusion of the pointing device), and can easily be customised by assignment of function keys.
In addition, it can optionally be supplied in stand-alone format, or as a panel for incorporation into OEM equipment designs.
The unique "Eyeball" pointing device can also be supplied as a stand-alone product for control applications in industrial equipment designs.
