Abstract
Rotation-monitoring detector comprising a binary output signal and a signaling LED, and including a frequency operating mode in which the state of the output signal and of the LED are a function of a passage frequency of a target in front of the detector. The detector includes a static operating mode in which the state of the LED is a function of a distance between the target and the detector. The detector comprises selection means, permitting the static mode and the frequency mode to be selected. The selection means are likewise used for the learning functions of the detector.
