Magnetic sensors are an important type of sensing element in modern systems. Switches, also referred to as solid state switches, are a particular type of magnetic sensor. The AN48841B-NL is an example of solid state switch. This document will discuss the application field and working principle of the AN48841B-NL.

The AN48841B-NL is a magnetic switch designed for applications that require reliable detection of an external magnetic field. The AN48841B-NL has an operating range from -40°C to +125°C. Its maximum operating voltage is 30 V and it can detect magnetic fields up to 2 Tesla. The switch has two output states: normally-closed (NC) and normally-open (NO). The AN48841B-NL can be used for a variety of applications such as door/window alarms, security systems, and water level monitors.

The working principle of the AN48841B-NL is based on the Hall effect. The Hall effect is a phenomenon in which a transverse electric field is produced in a conductor when a magnetic field is applied perpendicularly to the flow direction of an electric current. In other words, the AN48841B-NL uses the Hall effect to detect an external magnetic field. When an external magnetic field is present, the Hall element generates a voltage. This voltage is used to toggle the output state of the switch, either NO or NC.

The AN48841B-NL is a versatile magnetic switch due to its small size, wide operating temperature range, and its ability to detect a strong external magnetic field. It is suitable for a variety of applications such as security systems, door/window alarms, and water level monitors. The working principle of the AN48841B-NL switch is based on the Hall effect, which allows it to reliably detect an external magnetic field.
