Proximity Sensors: 9956-1900 Application Field and Working Principle

A proximity sensor is an electronic device designed to detect the presence of nearby objects without any physical contact. Proximity sensors are generally divided into two different categories: passive sensors and active sensors. Passive sensors detect the presence of an object by detecting physical contact or changes in the surrounding environment, while active sensors detect the presence of an object by emitting an electromagnetic signal and detecting the reflected signal.

9956-1900 is a type of electromagnetic proximity sensor. This type of sensor emits an alternating magnetic field and detects the change in the magnetic field generated in response to an external object. The 9956-1900 proximity sensor uses Hall Effect technology, which is based on the effect of an external magnetic field on a semi-conductor. When a metallic object enters the magnetic field of the proximity sensor, it creates a variation in the electrical current, which is then converted into a signal, which is then read by the sensor and used to detect the presence of an object.

Applications of 9956-1900 Proximity Sensor

The 9956-1900 proximity sensor is used in many practical applications, such as:

• Robotics: The 9956-1900 is often used in robots to detect objects in their path, allowing the robot to avoid them.
• Security systems: The 9956-1900 is used in security systems to detect intruders and to trigger a response, such as an alarm.
• Motion detectors: The 9956-1900 is used in motion detectors to detect the presence of people or objects within a certain range.
• Automated machines and equipment: The 9956-1900 is used in automated machines and equipment, such as assembly lines and manufacturing plants, to detect the presence of an object so that the machine can respond accordingly.

The 9956-1900 proximity sensor can also be used in many other applications where the presence or absence of an object needs to be detected.

Working Principle of 9956-1900 Proximity Sensor

The 9956-1900 proximity sensor operates on the principle of the Hall Effect. When an externally generated magnetic field is applied to a semi-conductor, an electrical current will be generated, called the Hall voltage. The magnitude of the Hall voltage is directly proportional to the strength of the magnetic field and the current passing through the semi-conductor.

When a metallic object enters the magnetic field of the 9956-1900, it causes a reduction in the magnetic field, due to its own magnetism. This reduction in the magnetic field is detected by the sensor and
