Inductive proximity sensors, proximity sensor targets, Touch switch, Long range. A proximity sensor is an electronic sensor capable of detecting the presence of nearby objects without physical contact.
It emits an electromagnetic field or a beam of electromagnetic radiation (for example: infrared) and then looks for changes in the return signal or field. The object that is being sensed is the proximity sensor's target. Depending on the proximity sensor targets, different sensors may be used. For example, an inductive proximity sensor requires a metal target, whereas a capacitive photoelectric sensor may be suitable for a plastic target. Absolute pressure sensor, electronic, high pressure, gas, Micro pressure sensor. Pressure sensors are used to monitor the pressure of fluids in pipes, hydraulics, engines and in nature.
Specialized sensors are also used in order to determine the pressure of gases or solids. Most modern pressure sensors work based on piezoresistance. Exterior motion sensor light, Security alarm, Electronic sensor, flood infrared. A motion sensor is an electronic device that is used for motion detection.
It contains an electronic sensor which quantifies motion and can either be integrated with or connected to other devices which alert the user of the presence of a moving object that is within the field of view of the sensor. Motion sensors are a vital component of comprehensive security systems for businesses and homes. An electronic motion detector contains a motion sensor which transforms the detected motion into an electric signal. Linear Hall Effect sensor, Magnetic field sensor, Magnetic field, Magnetic speed. A Hall Effect sensor is a transducer which varies its output voltage in reaction to a magnetic field.
These types of sensors are used for proximity switching, speed detection, positioning and current sensing applications. In its simplest form, it operates like an analog transducer, thus directly returning a voltage. Its distance from the Hall plate can be determined with a known magnetic field. By using groups of Hall Effect sensors, the relative position of the magnet can be determined. The electricity which is carried through a conductor will produce a magnetic field which varies according to the current. Laser linear position sensor, linear displacement, linear position sensors. A linear position sensor measures the linear position of a device.
The sensor reads the measurement in order to convert the encoded position into an analog or digital signal. This position can then be decoded into position by a digital readout or a motion controller. Light sensor programming, Contact image , charged coupled device, light sensor. A light sensor is an electronic device used to detect light.
There are several types of light sensors. A photocell or photo resistor is a small sensor which changes its resistance when light shines on it. A CCD (charged coupled device) transports electrically charged signals and can be found in digital cameras and night-vision devices. Photomultipliers detect light and multiply it. Linear sensor, image sensor chip, Image sensor manufacturers, Cmos image sensors. An image sensor is an electronic, photosensitive device which converts an optical image into an electronic signal.
It is composed of millions of photodiodes and is used as an image receiver in digital imaging equipment. An image sensor is capable of reacting to the impact of photons, thus converting them into an electrical current that is then passed onto an analog-digital converter. The most common types of image sensors are CCD and CMOS sensors.
