A change in oscillation occurs when the device detects any type of ferrous metal within the inductive proximity including aluminium, copper, brass, and iron. Inductive Proximity SensorsĪn inductive proximity sensor uses an oscillating circuit which generates an electromagnetic field. The receiver will detect obstacles that block the infrared radiation.
Both types of device use infrared (IR), however, a PIR sensor has a pair of pyroelectric infrared sensors in a magnetic lens which engage when the signal between them changes.Īn active IR sensor uses an IR LED that emits an infrared beam towards an infrared receiver. Infrared Sensors or IR sensors consist of Passive Infrared Sensors (PIR) and Active Infrared Sensors. The types of Distance Sensors available are: Infrared Sensors (IR Sensor) Although, different types of Sensor differ slightly dependant on type. Proximity Sensors transmit data about the presence or motion of an object via an electrical signal when the object is in the sensor’s range. They are designed to provide a high-speed response and have a general universal working principle. There are several types of Proximity Sensors, all of which are appropriate to various applications. Quicker response times than a contactor.Can be used in applications with an oil or water level.High speed motion sensor with non-contact properties.Used in a wide range of temperatures, ranging from -50☌ to 100☌.Motion detection of metallic & non-metallic objects.Some key features and benefits of proximity sensors include: They are non-contact devices, highly useful for working with delicate or unstable objects A proximity sensor is a component which is designed to detect the absence or presence of an object without the need for physical contact.
