Solid state magnetic sensors are devices that detect the presence of magnetic materials. Solid state magnetic sensors, also known as magnetometers, detect changes in the ambient magnetic field, temperature, pressure, or other factors and convert them into a readable electronic signal. The major application fields of these sensors are in electrical and electronic appliances, such as robots, consumer electronics, home appliances, medical devices, automotive electronics, and avionics. DN6853-A is a kind of solid state magnetic sensor switch which is primarily used in industrial and automotive applications.

DN6853-A is a miniaturized Hall-effect sensor switch with a built-in NPN open-collector output. It provides a reliable method for sensing the presence of an external magnetic field and is primarily used in industrial and automotive applications. The sensor is designed with a two-wire connection, enabling easy and fast installation. It has a wide operating voltage (13-30V) and a wide range of operating temperature (-40°C to +125°C). The device is also RoHS compliant and offers excellent cost-performance.

DN6853-A has two operating modes: open-drain output (WD), and push-pull output (PP). In open-drain mode, the output is “off” when the magnetic field strength is lower than the set threshold, and “on” when the field strength is higher than the threshold. In push-pull mode, the output is “on” when the magnetic field is lower than the threshold and “off” when the field is higher. The open-drain mode is used when the switching voltage is greater than the operating voltage, while the push-pull mode is used when the switching voltage is lower than the operating voltage.

The working principle of DN6853-A is based on the Hall effect. The Hall effect is the phenomenon that occurs when a current is passed through a conductor which is placed in a magnetic field. This current creates a voltage potential (Hall voltage) across the conductor such that the carrying electrons are deflected. The magnitude of this Hall voltage is proportional to the strength of the applied magnetic field and can be used to detect the presence of an external magnetic field.

DN6853-A is designed to optimize the detection of an external magnetic field. The Hall element is embedded into the sensor package and has a predetermined magnetic threshold. When a magnetic field with a strength higher than the threshold is present, the Hall voltage generated by the field will cause the sensor output to transition from off to on. The sensor output can then be used to control other devices such as relays, switches, and motors.

DN6853-A is a reliable and cost-effective solid state magnetic switch designed for industrial and automotive applications. The switch provides dual-mode responses and has a wide operating voltage and temperature range. It can also be used to detect the presence of an external magnetic field and is convenient for installation with its two-wire connection and integrated package.
