摘要： The present invention relates to a detector 10 for monitoring rotation, in front of which passes a target 19 wherein it is required that the passage frequency thereof be monitored with respect to a normal passage frequency, comprising a sensor unit 11 connected to a microcontroller 20 which delivers a binary output signal 15. Detector 10 includes means 30 for conversing with the operator, connected to the microcontroller 20 in order to set the detector 10 to a working mode or learning mode, which learning mode enables the microcontroller 20 to measure the normal passage frequency and enables an operator to select an operating range from a plurality of predefined ranges, through the conversational means 30. The microcontroller 20 calculates from the selected operating range, a triggering frequency and a resetting frequency.

摘要： The present invention relates to a self-adaptable proximity detector delivering a binary output signal (23) for the presence or absence of a target (19). The detector (10) includes a processing unit (15) and operates according to a short learning mode (AC) for an adjustment relative to its environment, according to a long learning mode (AL) for an adjustment relative to its environment and to a target (19), and according to a working mode corresponding to normal operation. The detector (10) comprises a variable digital storage resistor (14) driven by the processing unit in the learning mode and connected to the detection stage (12) so that variation of the value (R) of the digital resistor causes a variation of the switching threshold (SC) In the working mode, the processing unit (15) is in a standby state and the digital resistor (14) remains at its set operating value (RF)
