A proximity sensor is a gadget used to detect items even without coming into contact with them. This is a characteristic that has made them a mainstay gadget in different sectors including manufacturing, robotics, semiconductor, and many more among others. While inductive sensors detect metallic objects, capacitive sensors detect all the other objects. Ultrasonic sensors use sound wave reflections to detect the presence of all materials. However, put on proximity sensors can be used for the same application. If you are to find a sensor suitable for the intended use, to make sure that you are making the right choice. There are a lot of challenges associated with finding a suitable proximity sensor mainly because there are so many different types available for you to choose from. You must understand how you plan to use your proximity sensor before you start looking for one. Several elements can be taken into consideration regardless of the type of proximity sensor you need to help you find the right one. This site provides you with a detailed guide on how to find a proximity sensor regardless of how you plan to use it.
Consider the sensing distance you need. In simple terms, the sensing distance is the distance between the object to be sensed and the tip of the sensor. You can find the sensing distance of the different types of proximity sensors in the selection guide and the specifications table. It is recommended that you place the sensor far from the object to be sensed in many applications due to temperature concerns. More maintenance will be required if the sensor is placed too close to a high-temperature source since it is most likely going to fail much faster. With a triple range sensor and an extended sensor, you can soon achieve greater distance.
The space available for mounting the sensor also plays a part in your decision. Sensors come in different sizes and shapes. Regardless of the physical differences, the technologies used in the sensors are most like the same.
Consider the suitability of both shielded and non shielded sensors based on your application. Shielded sensors and non-shielded sensors are also referred to as embeddable and non-embeddable sensors. You can get longer sensing distances with unshielded senses. Shielded sensors on the other hand offer flush mounting.
You should also consider the environmental placement concerns before making a decision. Environmental factors such as elements such as contact with water, temperatures, contact with oil among others determine the type of sense of that is going to fit your application the most.
