Magnetic Sensors are one of the most useful components in modern technology. Magnetic sensors are used for a wide range of applications, from detecting the presence of a magnetic field to sensing distance and position. Magnetic Sensors are commonly divided into two categories: Switches (Solid State) and Inductive Sensors. The US5681ESE-AAA-000-SP is an example of a magnetic sensor in the switches (solid state) category.

The US5681ESE-AAA-000-SP is an integrated single-pole, double-throw normally open switch. It is designed for use in high-sensitivity detection applications, such as locating the position of a vehicle or detection of a magnetic field. The US5681ESE-AAA-000-SP is composed of a flip-flop integrated circuit and a Hall-Effect magnetic switch. The device is triggered when a magnetic field of sufficient strength is detected. The switch is activated when a field of 3 A/m is detected, and it is deactivated when the field returns to 1 A/m or lower.

The US5681ESE-AAA-000-SP is designed to operate with high sensitivity in a range of temperatures between -40°C and 85°C. The housing is made of a polycarbonate shell with a PVC coated cable and is available in two colors: white and black. The device is powered by a 3.3Vdc supply and consumes approximately 0.2mA. In terms of output, it is capable of sinking or sourcing up to 25mA.

When it comes to working principle, the US5681ESE-AAA-000-SP uses the Hall-effect principle to detect a magnetic field. The device is composed of a Hall-Effect transistor and a flip-flop integrated circuit consisting of two complementary transistors. The device is triggered when a magnetic field of sufficient strength is detected, which causes a voltage drop across the Hall-Effect transistor. This voltage drop is then converted into a logic state by the flip-flop circuit. When the magnetic field is reduced to below the trigger level, the switch resets itself and the output returns to its original state.

The US5681ESE-AAA-000-SP is an effective solution for applications requiring high sensitivity and low power consumption. It is a versatile switch that can be used in a wide range of applications, from vehicle position detection to sensing distance and presence of a magnetic field. The device is available in a variety of colors and voltage levels, making it suitable for many projects.
