A proximity Sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field and looks for changes in the field. The object being sensed is often referred to as the proximity sensor’s target. The maximum distance that this sensor can detect is defined nominal range. A proximity sensor measures current flow between the sensing electrode and the target provides readouts in appropriate engineering units.
• Digital output is standard.
• Analog output is available.
• Operating voltage: 5VDC
• Operating current: 300mA
• Sensing range: 0.5mm to 70mm
• A proximity sensor adjusted to a very short range is often used as a touch switch.
• Vibration measurements of rotating shafts in machinery
• Sheet break sensing in paper machine.
• Detection of weapons such as knives and guns, especially in airport security and other security systems.
