Proximity Sensors Proximity sensors are sensing devices used to detect the presence or absence of an object in the vicinity without having to be in direct contact. Commonly used for industrial automation, these types of devices are used to detect the presence or absence of objects such as tools, parts, and (in some cases) even humans in close proximity. The 9962-1602 Proximity Sensor is one such type, and in the following sections, we will look at its application field and working principle. Application Field The 9962-1602 proximity sensor is typically used in industrial automation for time-of-day, count-by-change, and single-cycle event applications. In time-of-day applications, the sensor is used to measure the duration of the event in order to determine the exact time that it took place. In count-by-change applications, the sensor senses when a target object has moved a certain distance, and records the number of times the event occurred. Finally, in single-cycle event applications, the sensor is used to detect the presence or absence of a single target object, which will trigger an action in response. Working Principle The function of the 9962-1602 proximity sensor is based on the principle of eddy current induction. When an alternating field is imposed on a stationary metal target object, an induced voltage is created in the target. This induced voltage can then be detected by the sensor, which is used to detect the presence or absence of the target object. The 9962-1602 detects this induced voltage by sending an alternating voltage through an induction coil. When the target object comes into close proximity of the sensor, it interacts with the alternating field, and an induced voltage is created in the target object. The induced voltage is detected by the sensor coils and can then be used to determine the presence or absence of the target object. The 9962-1602 also includes additional features such as adjustable deadzone and adjustable sensitivity, which allow users to fine-tune the sensitivity of the sensor in order to detect the target object over a wider range. This is typically used in applications where the presence or absence of a target object must be detected at a greater distance than the sensor’s typical detection range. Conclusion The 9962-1602 proximity sensor can be used in a variety of industrial automation applications, such as time-of-day, count-by-change, and single-cycle event applications. It functions on the principle of eddy current induction, whereby the alternating field imposed on a stationary metal target creates an induced voltage in the target. The 9962-1602 sensor then detects this induced voltage, which can be used to determine the presence or absence of the target object. Finally, adjustable sensitivity and a deadzone feature also allow users to fine-tune the sensitivity of the sensor in order to detect the target object over a greater distance.
