Abbreviation key

The abbreviation code reflects the type, nature and structure of a wire or cable in a simplified and abbreviated form. It is divided into several subgroups which, when read from the inside out, reflect the structure of a wire or cable. (All information without guarantee)

Abrasion resistance

Property of a cable, wire or material to withstand surface wear. (All data without guarantee)

ACR

ACR (Attenuation to Crosstalk Ratio) indicates the relationship between the near-end crosstalk and the attenuation at a certain frequency. (All data without guarantee)

ACS

Aluminium clad steel SS Stalum (All data without guarantee)

Actuator

An actuator is used to convert an electrically available signal into mechanical energy or other physical sizes. It is therefore the counterpart to the sensor, which converts energy into electrical signals. The actual action of the actuator is called actuation. It describes the generation of a movement or deformation. An actuator can, for example, be a valve in a control chain that opens or closes when an electrical signal is applied.

Adapter

An adapter is an element for connecting devices that do not work together. Adapters can be designed as plugs, plug-in cards, etc. (All information without guarantee)

Adhesion

Adhesive, adhesive and sealing properties of the outer sheath of a wire. The "low adhesion" property is important, for example, when using wires in drag chains to prevent them from sticking together. (All data without guarantee)

AENOR

Certification body: Asociacion Espanola de Normalizacion, Spain (All information without guarantee)

AES / EBU

Informal name of a digital audio standard created jointly by the AES (Audio Engineering Society) and the EBU (European Broadcast Union) organisations. The standard defines the transmission characteristics of the digital signal in order to simplify communication between devices. (All information without guarantee)

Ageing

Refers to the change in properties (preferably tensile strength and elongation) of a material as a function of time under specific conditions such as temperature, UV radiation, ozone influence, chemical and thermal stress, etc. (All data subject to change). (All data without guarantee)

Air section

Shortest air gap between two conductive parts. Clearances are specified by the rated impulse voltage. (All data without guarantee)

Alternating current

Alternating current is a current flow that periodically changes direction from positive to negative. The prerequisite for alternating current is an alternating voltage source such as a generator. (All information without guarantee)

Aluminium

If a copper conductor is replaced by an aluminium conductor with the same conductivity, it weighs only about half as much as the copper conductor, even though it has 1.6 times the cross-section. However, the larger cross-section requires increased material consumption of all subsequent components (insulation, sheaths, armouring, protective sheaths). (All data without guarantee)

Aluminium jacket

An aluminium sheath is lighter than a lead sheath. It has better conductivity and greater strength, but requires a plastic sheath as corrosion protection. (All data without guarantee)

Ambient temperature

The temperature of the air surrounding the equipment, determined under specified conditions. (All data without guarantee)

Amperage

Electrical unit, measured in amperes. Current = voltage/resistance. (All data without guarantee)

Ampere

Ampere is the strength of an electric current flowing through a conductor. Unit of measurement for the electric current. (All data without guarantee)

ANSI

Abbreviation for American National Standards Institute. A body in the USA that develops and publishes standards similar to the German DIN. (All information without guarantee)

Antenna cable

Antenna cables are coaxial high-frequency cables for receiver connections, house distribution networks and individual antenna systems. The main areas of application are: reception and distribution systems for radio and television broadcasting. Antenna cables must ensure low-reflection signal transmission.

Anti-ageing agent

As anti-ageing agents have a colouring effect on rubber compounds, they are usually only used for dark compounds. They prevent premature embrittlement of the compounds. (All information without guarantee)

Approved wires

Control and data lines with approvals, standards. Examples: VDE, UL/CSA, GOST-R (All information without guarantee)

ASI

Short for actuator-sensor interface. With ASI, only linear actuators and sensors in the lowest fieldbus range are linked to the first control level.bus system for the lowest automation level. Enables the simple connection of sensors, actuators and integrated systems to the first control level. See - Master/slave principle. Up to 248 binary inputs and outputs per network, information and energy on one wire, reverse polarity protected connection technology, 100m cable length or up to 300m with repeater, free tree structure of the network, protection class up to IP 67, cycle time <5ms, high interference immunity and fault tolerance. (All data without guarantee)

ASME

Abbreviation for American Society of Mechanical Engineers (USA). (All information without guarantee)

Assembly

Correct assembly of connection technology is important to ensure that connectors fulfil the guaranteed technical properties required for an application. Tighten the axial screw with a torque spanner. This is the only way to ensure a gas-tight, largely corrosion-protected connection of the copper stranded wire and consistently good transmission properties throughout the entire service life of the connector. (All information without guarantee)

ASTM

Abbreviation for American Society of Testing and Materials - USA. (All information without guarantee)

Asynchronous transmission mode

The asynchronous transmission mode can realise different transmission speeds and network expansions in communication networks. (All information without guarantee)

ATEX

Atmosphére Explosible. See -> Explosion protection. The term Atex is used colloquially as a synonym for the two EC explosion protection directives, namely Directive 94/9/EC [ATEX 95] and Directive 1999/92/EC [ATEX 137]. They concern the nature of components, equipment and protective systems for use in potentially explosive atmospheres and the minimum requirements for the installation and operation of systems in which explosive atmospheres are present. (All information without guarantee)

Atex approval

Atex approval is required for the intended use of devices and protective systems in potentially explosive atmospheres. (All information without guarantee)

AUI

Attachment Unit Interface. Designation of an Ethernet interface with a 15-pin D-Sub connector (All information without guarantee)

Auto-Crossing

Allows automatic crossing of the transmit and receive lines on twisted pair interfaces. This allows the application to use 1:1 wired and cross over cables equally. (All information without guarantee)

AWG

American Wire Gauge. AWG = American Wire Gauge = coding for the conductor cross-section. The smaller the AWG number, the larger the conductor cross-section. If the AWG number is smaller, the wire diameter becomes larger. The actual values (mm) depend on the wire resolution, depending on whether a rigid conductor or a stranded wire is used. (All data without guarantee)

AWM

UL designation for Appliance Wiring Material. (All information without guarantee)
