VL12N VL12F VL22N VL22FVL32FMeasurement is based on coil impedance detection.Resists temperatures up to 150? as standardInsensitive to temperature changesOffers fail-safe switchLow voltage operationDetection made at the end of the detectorWide sensitivity adjustment rangePrinciple of OperationMeasurement is based on coil impedance detection. A magnet and an electromagnet inside the detector vibrate the plate. Current that flows on the electromagnet decreases when the detector is covered by the measured material. The sensor detects this change to detect solid presence and gives an output.When the detector is not covered by the materialThe electromagnet vibrates at its operating frequency when alternating current is applied.Back electromotive force on the electromagnet becomes the largest due to change in magnetic field from the magnetThe sensor determines the detector is not covered by the material.When the detector is covered by the materialApplying alternating current does not cause the electromagnet to vibrate at its operating frequency.No back electromotive force occurs because the magnet is stationary.The sensor determines the detector is covered by the material.
