Magnetic Sensors - Switches (Solid State) have been widely used in a variety of applications, from industrial to consumer applications. The OH090U is a rugged and reliable Hall Effect switch designed for high temperature operations. The device has a range of operating temperatures from -40°C to +150°C. It is a single-chip sensor that contains a Hall effect element and a CMOS integrated circuit. This allows the device to be used in harsh conditions, such as high vibration environments and corrosive environments, without sacrificing robustness.

The OH090U has a number of features that make it an ideal choice for high temperature applications. First and foremost, it has a low power consumption, requiring as little as 1mA of current at 5V supply voltage. It also has a low magnetic sensing field of only 0.2mT, making it suitable for applications that require sensitive magnetic fields. Additionally, the device boasts fast response time and low hysteresis and provides accurate, reliable switching performance, even when exposed to extreme temperatures.

The working principle of the OH090U is based on the Hall effect. It utilizes the fact that a magnetic field, when applied to a semiconductor material, will create a voltage across it. The voltage can then be used to detect the presence of a magnetic field. The Hall effect sensor is placed on the same chip as the CMOS integrated circuit. The CMOS integrated circuit is used to process and amplify the signals coming from the Hall effect sensor. The device performs an analog-to-digital conversion, then sends the signal to an output pin.

When a magnetic field is sensed by the device, the output pin will produce either a 5V or 0V signal, depending on the configuration of the device. This signal can then be used to trigger external circuitry, such as a relay or a motor controller. This makes the device suitable for a variety of applications, such as sensing magnetic fields in patient beds or wheelchairs, in industrial machinery, and other applications where magnetic field sensing is needed.

The OH090U is a rugged and reliable device for use in high temperature applications. It features low power consumption and a low magnetic sensing field, allowing it to be used in a variety of applications. With fast response time, low hysteresis, and accurate and reliable switching performance, it can be used to trigger external circuitry in order to sense and control magnetic fields. The OH090U is a great choice for applications that require robust, high-temperature sensing.
