Magnetic sensors and switches are devices used for the operation of many electronic circuits. One of the most popular types of sensing devices is the reed switch. The A1130LUA-Y-T is a solid-state, low-power magnetic switch designed to detect the presence and/or absence of magnetic fields. It offers the added advantage of being triggered by either an AC or DC magnetic field.

The A1130LUA-Y-T magnetic sensor switch operates in a single package with a bipolar Hall effect transistor and an open-collector signal-conditioning transistor. The sensing element is attached to a conductive table, which is connected to external wires or traces for operation. This allows it to detect magnetic fields from as low as 10 millitesla (mT) up to as high as 32 mT, with a sensitive range up to 10 µT. The switching points are determined by externally connecting resistors and capacitors to the package.

The A1130LUA-Y-T works by utilizing the Hall effect to detect changes in the magnetic field. When a magnetic field is applied to the sensing element, a voltage is generated which is proportional to the strength of the magnetic field. This voltage is compared with the reference voltage, which is applied across the chip. When the voltage exceeds the reference voltage, the internal transistor is switched on. This connection allows the output pin to switch on and off and detect the presence or absence of a magnetic field.

The A1130LUA-Y-T is used for a range of applications within many different industries including aerospace, robotics, automotive, medical, communication, industrial automation, and consumer electronics. Sensor switches can be used as proximity sensors, for motion detection, as a presence/absence detector, for contactless position sensing, or for touchless control. In automotive applications, it can be used to detect the position or presence of components, such as parts of a steering mechanism, to ensure a safe operation.

The A1130LUA-Y-T switch is ideal for applications requiring low power, low-cost solutions, and is designed to offer superior performance in low-field, AC or DC, magnetic applications. It is suitable for medium-range applications and designed to operate in a wide temperature range. The package size is conveniently small, making it easy to integrate into other circuitry. This makes it an excellent choice for cost-effective, accurate, and reliable operation.

The A1130LUA-Y-T switch is suitable for applications where a smaller and lightweight design is required and it is certified for use in high reliability, safety critical operation. It is flexible and can be used in a variety of applications. The solid-state design and reliability make it a popular choice for magnetic sensing and switching requirements.
