Solid state magnetic sensors (switches) have been used for decades to detect and ultimately interpret the presence or absence of a magnetic field. One of the most common examples is the hall-effect sensor, which uses a changing magnetic field to detect the motion of a metal object such as a lever, wheel, or other magnetic device. More recently, the OHS3119U has emerged as the latest innovation in solid state magnetic sensors.

The OHS3119U is a Hall Effect switch which senses both the direction of the magnetic flux and the polarity of the magnetic field, and can act quickly to open and close an integrated relay. It offers an ultra-broad detection range (up to 30A/m) and is capable of detecting the presence of a magnet in over 400 distinct positions. This makes the OHS3119U ideal for applications where precise control and continuous monitoring of the magnetic field is required, such as in door or window switches, motor speed or movement detectors, vending machines, security control systems, and many other similar applications.

The OHS3119U is composed of two sensing elements: a Hall Effect switch and a Hall Effect amplifier. In the presence of a magnetic field, the Hall Effect switch generates an output voltage that is proportional to the strength of the field. This output voltage is passed on to the Hall Effect amplifier, which amplifies the signal and outputs a logic high when the strength of the magnetic field exceeds a preset level. This logic high can then be used as an input to a microcontroller, relay, and other digital logic components for control and integration into a system.

The OHS3119U also features an “auto-shutoff” function, which will automatically disable the device when no external magnetic field is present. This ensures that the device is not always active, which improves battery life and helps reduce overall system power consumption. Furthermore, the OHS3119U is protected against electrostatic discharges, which makes it suitable for use in environments with high levels of electrical noise.

Overall, the OHS3119U is a reliable and cost effective solution for applications requiring high precision detection of a magnetic field. Its broad detection range and wide detection range make it suitable for use in a variety of applications, from motion detectors to door and window switches. Its integrated auto-shutoff functionality not only ensures reliable results, but also helps reduce system power consumption. As a result, the OHS3119U is an ideal choice for any application requiring a solid state magnetic sensor.
