Thanks to the extremely wide measuring range they can be even used to control repetitive operations, signalling in case of unavoided stops. Further delays or other special functions are implementable upon specific request. The output is protected against connection mistakes, overvoltages on lines, and short circuit of the load. The connection is possible with a 4 wires M12x1 connector which must be ordered separately. BDC Electronic - Viale Lidice, 37/39 - 10095 Grugliasco (To) - Italy -Tel.

SPEED SENSORS Example of application Motor Motor Power Sensor 2 White 4 Black 3 Blue On power on, the yellow LED goes on and the output switches in ON state, driving the relay, which will drive the motor. After a start up delay time (T1) the sensor measures the speed of the motor and compare it to the threshold value. If the speed is under the threshold value, the output goes OFF, turning off the LED. The minimum threshold can be either factory presetted or can be acquired from the sensor directly on the application with no need to perform any measurement.
