Magnetic Sensors - Switches (Solid State) include a variety of products and technologies, one of which is the EW750B. This product consists of a magnetic sensing element combined with a special plastic package containing the electronics necessary to convert the sensed magnetic field into a digital and/or analog signal. The output interface of the EW750B includes an analog voltage output, digital pulse output, output LED indicators, and an open collector switch output.

The primary application is the detection of metal objects such as key tags, coins and tools. This type of device is also used in access control, automation, safety systems, vending machines, gaming machines, and home security systems. With a wide range of operating temperatures, the EW750B is well suited for industrial applications.

The reliable functioning of the device is ensured by a solid state switching system. This system works by detecting changes in a magnetic field and then converting this change into an electrical output. The angle of detection and field strength can be adjusted to facilitate more accurate readings.

The response time of the EW750B is typically between 1 and 2 milliseconds, which makes it ideal for applications requiring fast detection of metal objects. The solid state switch inside the device is an active component that does not require any external power sources to function, which further decreases power consumption and increases reliability. One of the major advantages of this device is its low associated cost.

The operating principle of the EW750B is based on the Faraday’s Law of Electromagnetic Induction. As an external magnetic field is applied to the device, the induction current in the internal circuit generates an electrical current, which is then converted into an electrical signal that is outputted. The output voltage is adjusted based on the magnitude of the magnetic field strength. The amplitude of the output voltage is proportional to the strength and size of the magnetic field.

In addition to its magnetic sensing capabilities, the EW750B can also be used to detect the presence of an electrical field. This feature is useful in applications such as motor control, proximity sensing, and security systems. The device can also be used in combination with a microcontroller for additional control and monitoring applications.

To facilitate the integration of the EW750B into an existing system, the device is available in a variety of formats, including analog and digital. Additionally, the device can be interfaced with various types of transducers, making it suitable for use in a wide range of applications. This product is highly reliable since the device has been thoroughly tested and certified. The EW750B is also very cost effective, making it ideal for volume markets.

In conclusion, the EW750B is a highly versatile magnetic sensing device which is widely used in access control, industrial automation, safety systems, vending machines, gaming machines, and home security systems. The device is exceptionally reliable and has a fast response time, making it ideal for applications requiring the detection of metal objects. Furthermore, the EW750B can be easily integrated into an existing system, and it is extremely cost-effective.
