What is a Proximity Sensor?
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. Proximity sensors have a long functional life and high reliability due to the absence of mechanical parts and the lack of physical contact between the sensor and the target. A proximity sensor that is adjusted to a very short range can often be used as a touch switch.
Types of Proximity Sensors
There are many different kinds of proximity sensors. At Future Electronics we stock many of the most common types categorized by type, supply current, supply voltage, packaging type and output type. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common values for supply current are 10 mA and 15 mA. We also carry proximity sensors with supply current as high as 500 mA. Supply voltages can be up to 200 V, with the most common chips having a supply voltage of 2.7 to 3.6 V and 2.7 to 5.5 V.
