Technology Overview
The document discusses the perfection of piezo technology, highlighting its function and advantages. The technology is suitable for harsh environments, being water and dustproof, and is usable both indoors and outdoors. It features a sealed metal surface that is vandal-proof and easy to clean. With no moving parts, it boasts a long life expectancy, tested for 50 million cycles, and reduces maintenance needs, thus lowering service costs. The technology allows for versatile mechanical configurations, being manufacturable in any shape.

Applications
Piezo technology is applicable in various fields including vending machines, lifts, beverage dispensers, safety and security systems, public internet kiosks, chemical and petrochemical industries, food industry, medical equipment, mining equipment, industrial machinery, and white appliances.

Technical Data
The technical specifications include a rated voltage of 1-24 V AC/DC, rated current of 200 mA – 1A, actuation force typically between 3 - 5 N, and an operating temperature range from -20°C to +75°C. The protection system is rated IP68/69, and the switches can be illuminated with LED rings at 5VDC, 12VDC, or 24VDC.

Switch Functions
The switch functions are based on the piezo effect, where an external push force activates a piezo element to release voltage for switching. The available functions include momentary (120 msec pulse), continuous (circuit closed as long as the switch is pressed, up to 6 seconds), and toggle (switch changes position at each activation).

Product Range
The document details various switch models such as SMF, SBS, SMA, SBA, SBR, SML, BPS, and TACTILE, each with specific functions, materials, anodize colors, dimensions, and illumination options. Custom-made switches are available for unique product configurations, supported by Baran's engineering department.

Keypads and Keyboards
Utilizing patented technology, a wide range of keypads, keyboards, and input devices are offered. Keypads come in various configurations such as KBA, KBF, and KBH, with different output matrices and surface materials. Keyboards include full-size and reduced-size options with integrated pointing devices. Custom-made options are available, offering various surface materials, colors, functions, and interface connections.
