Magnetic sensors - switches (solid state) are mechanical devices used to detect or monitor motion, position, or presence of a ferrous metal object by sensing its magnetic field. As a result, they are often referred to as “magnet switches” or “proximity switches”. AH372-P-B is a type of magnetic sensor switch - a solid state switch with two channels that are integrated with a passive Hall-Effect sensor.

AH372-P-B offers an improved active high output and is designed for inductive positioning and detection applications. It is built around a precision Hall-Effect element that provides precise switching points and temperature stability over a wide operating temperature range (-20 to +85°C). The device\'s output voltage is proportional to the strength of the external magnetic field, and its switching characteristics depend on the physical configuration of the magnetic field, such as loop shape and flux density.

The AH372-P-B is designed for use in applications where it is necessary to measure or detect the position and strength of a magnetic field. This type of sensory device is commonly used in a variety of applications, including motor control, positioning systems, door open/close sensors, security system monitoring, and automated industrial and automotive systems.

To use the AH372-P-B, the physical configuration of the magnetic field must be created around the device. An example of this would be a loop of ferrous metal around the device\'s sensing range. This would result in a fluctuating magnetic field which can then be monitored by the AH372-P-B. The device\'s two switch outputs will be activated when the strength of the magnetic field is within the detection range.

The principal operation of AH372-P-B is based on a Hall-Effect principle. When the device is exposed to a magnetic field, the Hall-Effect element in the device generates a voltage proportional to the strength of the magnetic field. The Hall-Effect element is a solid-state device that senses changes in magnetic fields and converts them into electrical signals. The device has two output channels that are used to switch on and off a load.

The AH372-P-B device also offers the user a selectable output switch type (active or passive) and adjustable hysteresis. Active switch type is usually used in applications where load current is low, while passive switch is more suitable for applications with high load current. Hysteresis is a feature that allows the device to maintain its output state over a wide input range, rather than requiring different input levels to trigger the respective outputs.

The AH372-P-B has many features that make it suitable for numerous applications such as motor control, positioning systems, door open/close sensors, security system monitoring, and automated industrial and automotive systems. Offering superior performance, high accuracy and temperature stability, the AH372-P-B is a reliable and easy-to use solution for sensing magnetic fields.
