The A1104LUA-T is a low-cost, high-performance linear Hall-effect sensor, ideal for applications that require precise, non-contact position sensing. This type of device is a kind of Magnetic Sensor - Switch (Solid State). It has various fields of application and a simple working principle.
A1104LUA-T is mainly used for angular and linear motion sensing. It can be applied in various fields, such as motor mount position sensing, automotive transmission shifter position sensing, automotive steering wheel position sensing, medical instrument position sensing, factory automation position sensing, consumer electronics, home appliances, and safety/security systems. The sensing application requires a switch signal which can be used for digital device outputs. The switch output is a contactless way to get signals, and has low power consumption compared to other mechanical methods.
The A1104LUA-T has a wide operating temperature range, up to 130 ºC. It provides high precision and repeatability, stable supply current, tolerance to EMI, and an operating range of 2~6 V. The output can be configured as open drain, push-pull, or low side/high side switch.
The working principle of the A1104LUA-T is magnetic sensing. Its embedded sensing element is a Hall-effect switch, which is a type of solid-state device that senses the presence of a magnetic field. It works on a simple principle: when exposed to a magnetic field, it generates a voltage proportional to the strength of the magnetic field. This voltage is amplified and then sent to a comparator, which produces a digital signal when the voltage has reached a certain threshold. This signal can then be used as an output for various kinds of digital devices. This allows the device to detect the presence of magnets and respond accordingly.
The A1104LUA-T is a powerful and reliable magnetic sensor switch (solid state) that can be used for various applications. Its wide operating temperature range makes it suitable for many types of applications. It has a simple working principle and is easy to use. With its high precision and repeatability, it can offer reliable switch output for a variety of applications.
