Proximity sensors are transducers that measure the distance between an object and the sensor. They can detect the presence of an object without the object needing to make contact with the sensing element. Proximity Sensors can be divided into two groups: non-contact and contact. Non-contact sensors use ultrasonic or light waves (optical or infrared) to detect the presence of an object, while contact sensors (or proximity sensors) use electrical currents to determine the presence of objects. Moreover, depending on the application field, Proximity Sensors are further divided into inductive, capacitive, magnetic, and photoelectric sensors.

9961-0202 is one type of Proximity Sensors. It uses capacitive sensing technology and comes with a range of sensing distances, from 0-3mm to 0-32mm. The 9961-0202 is designed for use in medium- to high-voltage applications. It has two main parts: the sensing element and the controller. The sensing element generates an electric field between the two electrodes separated by a dielectric material (e.g., foam or air gap). The controller measures the capacitance between the two electrodes to detect the presence of objects. The 9961-0202 is a highly reliable and accurate Proximity Sensor, capable of detecting objects in any medium without requiring calibration.

9961-0202 can be used in a variety of applications, such as level and flow control, presence detection, and positioning. It is particularly suitable for use in hazardous environments due to its high shock and vibration tolerance, and it has a high tolerance for extreme temperatures. The 9961-0202 also features a short response time and high switching frequency. It is suitable for use in machines where fast response times are required.

The working principle of the 9961-0202 is fairly simple. It uses capacitive sensing to detect the presence of an object. When the sensing element is powered, an electric field is generated between the two electrodes. When an object is brought close to the sensing element, the capacitance between the two electrodes increases. This increase in capacitance is detected by the controller, which then signals a “detection” point and triggers the desired action.

9961-0202 is an excellent choice for applications that require fast response times and high accuracy. It is simple to use and highly reliable, and it can withstand extreme temperatures and shocks. It is also well-suited for use in hazardous environments. With its range of sensing distances and applications, the 9961-0202 is an ideal Proximity Sensor for many industrial and commercial applications.
