Description
The LJ12A3-4-Z is Inductive type prox switch with NPN Normally Open transistor switch. Output upon detection.
A proximity sensor is an electronic sensor that is used to detect the presence or absence of nearby objects without physical contact. Proximity sensors are commonly used in a wide range of industrial and consumer applications, such as robotics, automation, security systems, and mobile devices.
There are several types of proximity sensors, including inductive, capacitive, magnetic, and optical sensors. Each type of sensor operates based on a different physical principle, such as detecting changes in electrical capacitance, magnetic field strength, or light reflection.
