Magnetic sensors - Switches (Solid State)
The A3281ELHLT is a low-cost magnetic switch sensor which is a two-wire device used to detect the presence of a magnetic field or the location of a magnetic field. The device is constructed in a slim, low profile, plastic package making it ideal for applications such as miniature board assembly and monitoring dynamic systems. It provides a low-cost solution for insuring that critical components are performing properly.The switch comes with five essential features: two-wire power, a built-in sensor, an external magnetic field detector, a power switch, and an output port.Application Field
The A3281ELHLT switch can be used in a number of exciting applications, including:• Security and safety: To detect the presence of a magnetic field to enable alarm systems, door locks, cameras, sensors, lighting control, and other security applications• Manufacturing: To monitor the alignment of parts on the assembly line and ensure quality control• Medical: To detect the presence of a magnetic field to alert medical professionals to potential health issues• Transportation: To detect the presence of a magnetic field to enable traffic control systems, rail-yards, and navigation systemsWorking Principle
The A3281ELHLT works by detecting the presence of a magnetic field. The device contains a built-in sensor that can detect the change in the magnetic field in a varying and unpredictable manner. The device is powered and produces an output signal when there is a change in the magnetic field. The device includes a power switch to turn the device on and off.The output signal is proportional to the change in the magnetic field. The device is sensitive to changes in the magnetic field from both the static and dynamic fields. The device’s output signal is also affected by the strength and direction of the magnetic field.The device is easy to install and requires minimal maintenance. It is ideal for applications in which the device must be able to detect a change in the magnetic field at a distance and in difficult to access locations.The A3281ELHLT is a low-cost, reliable device which provides a cost-effective solution for a number of applications making it an ideal choice for many users.The specific data is subject to PDF, and the above content is for reference
