Magnetic Sensors - Switches (Solid State)

The DN6849S magnetic sensor switch is a solid state, non-contact switch that is designed for sensing the presence or absence of magnetic materials. The DN6849S is a type of Magnetoresistive (MR) switch, which is based on the principle that certain magnetic materials, such as amorphous alloy, change their electrical resistance when in the presence of an external magnetic field.

Usage

The DN6849S can be used for a variety of applications, such as security systems, burglar alarms, magnetic encoders, access control systems, and industrial automation. It is also used in gaming machines, vending machines, ATMs, door locks, and other devices that require an accurately sensed magnetic field.

Installation

Installation of the DN6849S is relatively easy. The sensor has two components: an adjustable ferromagnetic core and a housing. The housing is designed to allow for moderate levels of water and dust resistance. The ferromagnetic core is adjustable, which allows different sensitivities to be set. This makes it ideal for different applications.

Working Principle

When a magnetic material is placed near the DN6849S magnetic sensor switch, an external magnetic field is generated. This field is detected by the amorphous alloy in the DN6849S, which changes its electrical resistance. TheDN6849S is designed to be sensitive to certain levels of magnetic fields, which can be adjusted with the ferromagnetic core. When the level of the magnetic field reaches the set threshold, the resistor is activated and the device switches on or off.

Applications & Benefits

The DN6849S magnetic sensor switch is an ideal choice for applications that require accurate sensing of magnetic fields. It can be used in a variety of environments and can be easily installed with minimal effort. It offers the benefit of greater reliability and longer life than traditional mechanical contact switches.The DN6849S is also a great choice for applications that require a lot of flexibility, as it can be adjusted to different levels of sensitivity. It’s also relatively economical, making it suitable for use in many cost-sensitive applications.In conclusion, the DN6849S is an excellent choice for applications requiring accurate sensing of magnetic fields. It’s easy to install and adjustable to different levels of magnetic field sensitivity. It also offers greater reliability and longer life than traditional mechanical contact switches.
