What Are Position Sensors? Types of Position Sensors
Position sensors are devices that can sense the position of an object being measured and convert it into a usable output signal. They can sense the position of the measured object and convert it into a usable output signal.Position sensors can be used to detect position, reflect the state of a switch, and differ from displacement sensors. Position sensors can be divided into two types: contact sensors and proximity sensors.1. Contact SensorsContact sensors operate by the contact and compression of two objects. Common examples include limit switches and two-dimensional matrix position sensors. Limit switches have a simple structure, reliable action, and low cost. When an object collides with the limit switch during movement, its internal contacts will act, thereby completing control. For example, if limit switches are installed at both ends of the X, Y, and Z axes of a machining center, they can control the movement range. Two-dimensional matrix position sensors are installed on the inner side of a robotic hand to detect the contact position with an object.2. Proximity SensorsProximity switches are switches that can emit an “action” signal when an object approaches it within a set distance without direct contact. There are many types of proximity switches, mainly including electromagnetic, photoelectric, differential transformer, eddy current, capacitive, reed switch, and Hall effect types. The application of proximity switches in CNC machine tools mainly includes tool holder selection control, worktable travel control, and cylinder piston travel control.(Source: This text is reproduced from OFWEEK.
