Introduction

US3881EUA-AAA-000-SP is an integrated magnetic sensor switch solution from US-based manufacturer US-Sensors Corporation. It is designed to provide an efficient and reliable method for detecting the presence of magnetic fields. The device integrates a sensing element plus an integrated switching output in a single package. The package works best when sensitive to alternating current (AC) magnetic fields at frequencies up to 60Hz in size. It works best in medium to high sensitivity ranges and is typically used for switching or safety applications.

Technical Parameters

The US3881EUA-AAA-000-SP has an operating temperature range of -40°C to +110°C. It has a maximum current load of 30mA, a voltage rating of 24VAC/DC, and a maximum current consumption of 3mA. It can detect alternating magnetic fields up to 60 Hz in size. The detection range is medium to high, making it suitable for most switching or safety applications.

Application fields

The US3881EUA-AAA-000-SP is suitable for a variety of applications. It can be used in commercial and industrial settings, in medical equipment, in temperature controllers and sensors, as a door opener, and in security systems. The device can also be used to regulate fans and other moving parts, as well as to control motion detection or close proximity sensing. In addition to these, the US3881EUA-AAA-000-SP can be used in signal or sensor circuits in order to detect electric or magnetic pulses or fields.

Working Principle

The US3881EUA-AAA-000-SP works by detecting the presence of a magnetic field in the medium to high sensitivity range. When the field is present, the device detects the change and sends an electrical signal to the output terminal. This triggers the appropriate action as programmed by the user. The device is available in both an open collector (OC) and a transistor output (TO) type configuration. The OC type features an on-chip pull-up resistor to the supply voltage while the TO type features an open-collector output with a user-programmable current limit.

Conclusion

The US3881EUA-AAA-000-SP magnetic sensor switch is an integrated solution that provides a simple and reliable way to detect the presence of magnetic fields. The device has a medium to high sensitivity range and can detect frequencies up to 60Hz in size. The device is suitable for a wide range of applications, including commercial and industrial settings, medical equipment, temperature controllers and sensors, door openers, motion detection, close proximity sensing, and signal or sensor circuits. The US3881EUA-AAA-000-SP works by detecting the change in the magnetic field and sending an electrical signal to the output terminal to trigger the predetermined action.
