Electronic component to transform a permanent analog signal into a stepped digital signal. A typical application is the conversion of an analog measured value into a digital signal, for instance, for further processing in a personal computer.
Angle scale
Scale to show the angle position on circular saws.
Anti-splintering device
The anti-splintering device is a (transparent) insert for the jigsaw base plate to prevent splintering when cutting through sensitive or brittle surfaces.
In water technology: a non-return valve integrated into a hose connection. Hoses under pressure can be connected and disconnected without splashing or loss of water.
