Proximity Sensor ICs
Proximity sensor ICs (integrated circuits) are sensing devices designed into printed circuit boards and are ideal for detecting an object’s presence or absence within the sensor’s defined distance. These sensors trigger various functions by integrating them within a circuit. They come in various sensor types with a wide range of domestic and industrial applications.
Proximity Sensor ICs Types:
Depending on the system requirements and users’ end goals, various types of proximity sensor ICs suit a wide variety of applications. Some significant types of sensing devices include inductive, capacitive, and infrared sensing, which are ideal for a wide range of applications and sensing environments.
Various proximity sensor ICs are available, using a range of senses.
- Inductive proximity sensors
These sensing devices are designed to detect metals or metallic objects using an electromagnetic field. The integral sensors detect the oscillations up and down upon detecting metallic objects in the vicinity. These variations result in generating output signals that are detected via a threshold circuit. The sensors’ size, type, and shape verify the operating ranges or the type of object the sensor is detecting.
- Capacitive proximity sensors
Capacity proximity sensors are designed to detect metals and non-conductive materials. Unlike inductive sensors, capacitive proximity sensors detect objects using electrical fields. These sensors change their states triggered by the capacitance changes in the sensing areas. These sensors are widely used in a variety of applications. For instance, proximity sensors are used in various smartphones. When the phone is held closer to the ear, the sensor detects it as an object and switches off its screen. Other examples include their use in switches that sense variations in hand gestures.
What are the uses of proximity sensor ICs?
Proximity sensor ICs are ideal for non-contact sensing applications integrated within circuits. They are mostly found to use in:
- Parking sensors
- Machine automation
- Proximity alarm systems
- Mobile phones
- Military applications.
