Detector Switches are used to“detect”internal mechanical movements and convert human manual operations, such as the opening of a door , to electronic signals. In some applications, Detector Switches are used to replace encoders as a lower cost solution.
When people enters the room or moves inside the room, the speed of the returning sound waves changes, triggering the switch. The sensor uses a photodetector, which converts light in the wavelengths into electrical current that triggers an alarm in the minicomputer housed in the detector, activating the switch.
