Abstract

L'invention concerne un module détecteur (1) dans un système de commande de vitesses automatique dans lequel sont disposés plusieurs détecteurs (8, 9, 10, 11, 12). Le module détecteur (1) peut, à l'aide d'éléments de fixation (5, 6), être monté sur des points de fixation adéquats du système de commande de vitesses automatique. En groupant certains détecteurs individuels (8, 9, 10, 11, 12) en un module détecteur (1), on évite la création de raccords de câbles individuels et le module détecteur (1) pourra, par exemple, être relié à une unité de commande et de régulation du système de commande de vitesses automatique via une seule interface électrique (7).
