1D Code
A 1D code, also known as barcode or one-dimensional code, is a code whose optical aquisition is made in an unidimensional way.

1D/2D Scanner
A 1D/2D scanner is a scanner that can read and process both 1D codes (1D code) and 2D codes (2D code).

2-Wire Devices
At 2-wire devices, load is connected in series to supply power.

2D Code
A 2D code, also known as a two-dimensional code, consists of a pattern of dark and light elements (bars, rectangles and squares with corresponding spaces in between) which are arranged in a 2D fashion. 2D codes have a more complex layout than 1D codes, and the technology required for acquiring and deciphering them is more complex as well as the scanner must always read the entire pattern depicted by the barcode in order to acquire and decipher 2D codes, and not just a horizontal line as is the case with 1D Codes. Two-dimensional codes contain more diverse information than one-dimensional codes, for example information for the identification of products, texts such as addresses, and delivery note numbers. In general, we differentiate within the 2D codes between the stacked codes (stacked code) and the matrix codes (DataMatrix code).

2D Code Scanner
A 2D code scanner is a scanner which operates according to the principle of an image processing system. It is equipped with a CCD or a CMOS element plus an integrated illumination and scans (scanning) a defined surface area depending on the selected scanning range. Thus, it is capable of reading 1D and 2D codes omnidirectionally.

3-A SSI
3-A SSI is an organization which sets standards in the field of food and beverages in close cooperation with the FDA. It is comparable with the EHEDG in Europe. Components in closed processes (e. g. piping) can be certified by 3-A SSI. Certified components bear the 3-A logo. Components in open processes (e. g. conveyor belts) cannot be certified.

3-Stage Enabling Switch
3-stage enabling switches (enabling switch), in comparison to 2-stage enabling switches, have the advantage of always ensuring safe shutdown in emergency situations regardless of individual user operation (release or pressing – in the event of a cramp). Mode of operation of a 3-stage enabling switch:

3D Tracking
3D tracking is the sum of rotary tracking or translatory tracking plus auto-focus. Objects are tracked with regard to the X and Y positions and are reliably detected by auto-focus at various working distances.

6-Band Multispectral Sensor
In a 6-bank multispectral sensor, the spectrum of visible light is broken down into six ranges including red, orange, yellow, green, blue and violet (ROYGBV color space). This makes it possible to detect extremely fine color nuances thanks to spectral measurement.

Absolute Pressure
Absolute pressure is pressure relative to zero pressure in an empty space (vacuum). Example: Atmospheric pressure (ambient pressure / air pressure) has an absolute value of approximately 1 bar and a relative value of 0 bar.

Absorption
Absorption is a process in which the radiant energy of a light beam passing through a medium is partly or fully converted into another form of energy, e.g. heat.
