The A3251EUA-T is a low-cost, low-power magnetic sensor switch that is used in a variety of applications. This switch uses a magnetically operated Hall effect to detect the presence or absence of a magnetic field, allowing for the detection of switching operations. The switch is small in size and can be used in a wide range of applications.

The A3251EUA-T operates at a power supply voltage range of 3 to 24VDC, and energizing current of 0.45mA. It has a response time of 3ms and a rating of 0.3A at 13.2VDC. The operating temperature range is -40C to +85C and the storage temperature range is -40C to +125C. The A3251EUA-T can detect magnetic fields from either a north or south pole. The output is an open-collector with an ON state with a pull-up resistor on the output pin.

As a magnetic switch, the A3251EUA-T is ideal for detecting the presence of a permanent magnet in a variety of applications. It can be used in security systems, intruder alarms, latch detection, and with products such as door locks, drawers, and cash boxes. The switch can also detect movement in a permanent magnetic field, making it useful for sensing weight or vibration. The A3251EUA-T can be used to monitor the position or speed of a motor.

The working principle of the A3251EUA-T is based on the Hall effect. This effect is a phenomenon in which an electric current flowing through a conductor is subjected to a transverse electric field, resulting in a voltage perpendicular to the direction of the electric field. The Hall effect is used in a variety of applications such as transducers, motors, and magnetic sensors. The A3251EUA-T uses the Hall effect to detect the presence or absence of a magnetic field.

The A3251EUA-T magnetic switch is a reliable and cost-effective solution for a wide range of applications. With its low power requirements and small size, the A3251EUA-T can be used in battery-powered devices, making it ideal for applications such as security systems and motor control. The switch is easy to install and can detect the presence of a magnetic field, allowing for the detection of switching operations. The A3251EUA-T is an ideal choice for applications requiring a reliable and cost-effective magnetic sensor switch.
