Magnetic Sensors - Position, Proximity, Speed (Modules)

Position, Proximity, and Speed Module sensors are highly versatile devices used in various industrial applications to detect the presence, absence, or motion of an object based on the surrounding magnetic field. These sensors are designed to operate with either the north or south pole of a magnet, depending on the specific device and its intended purpose. Here is a detailed description of the different types of modules within this category:

Ball switch: This type of module utilizes a small metal ball that rolls within a housing. When exposed to a magnetic field, the ball either makes or breaks contact with electrical terminals, enabling object detection or position sensing.

Bipolar switch: These modules have two switching thresholds—one for the north pole and another for the south pole. They offer a versatile solution for detecting both polarities of a magnetic field.

Hall effect sensors: These sensors utilize the Hall effect phenomenon to measure changes in a magnetic field. They provide accurate proximity or position sensing capabilities and are commonly used in industrial automation and robotics.

Logic magnetic pickup: Designed specifically for detecting the rotation of gears or other rotating machinery, logic magnetic pickup modules use a magnetic field to generate digital output signals indicating speed or position changes.

Omnipolar sensors: These modules are capable of detecting the presence of both the north and south poles of a magnet, making them ideal for applications where the polarity of the magnetic field may vary.

Potentiometer sensors: Potentiometer modules employ the relative movement between a magnet and a potentiometer to measure linear or angular positions. They provide analog output signals that are proportional to the position being measured.

Reed switch sensors: Reed switch modules consist of two metal reed contacts enclosed in a glass tube filled with inert gas. They are highly reliable and find applications in proximity detection, limit switches, and security systems.

Unipolar switch: These modules are sensitive only to one polarity of the magnetic field, either the north or south pole. They are widely used in industrial applications requiring precise proximity detection.

Variable reluctance speed (VRS) sensors: VRS modules detect the rotation speed of a gear tooth or ferromagnetic target by measuring changes in magnetic flux. They are commonly used in automotive applications for speed sensing.

Position, Proximity, and Speed Module sensors play a crucial role in industrial automation, robotics, and automotive industries. Their high sensitivity, accuracy, and reliability make them indispensable for tasks such as object detection, position sensing, speed measurement, and motion control in industrial environments.
