Magnetic sensors are used to detect and measure the magnitude of a magnetic field in a wide range of applications. They are commonly used to measure the presence and magnitude of an external magnetic field, such as the Earth’s magnetic field or the magnetic field of a motor. Magnetic sensors are widely used in industrial automation, robotics, test and measurement, medical, automotive, and aerospace industries. The A1123ELHLX-T is a magnetic switch or solid state sensor designed to quickly and accurately detect when a threshold magnetic field is exceeded.

A1123ELHLX-T Application Field

The A1123ELHLX-T switch is a solid state neodymium magnet with a moveable switch contact for sensing magnetic field strength. The A1123ELHLX-T switch is ideal for applications that require a reliable, low-cost, and small sensor with extended sensing range, high sensitivity, fast response, and high stability in the presence of a large magnetic field. It offers excellent insulation resistance, making it an ideal choice for applications in hazardous locations and/or high vibration areas. The switch is also resistant to shock and vibration, making it suitable for use in a wide variety of industrial, commercial, and residential applications.

A1123ELHLX-T Working Principle

The A1123ELHLX-T switch utilizes an electromagnetically actuated moveable switch contact to detect a threshold magnetic field strength. When the ambient magnetic field outside the switch exceeds the predetermined threshold, the switch contact is actuated and an electrical signal is generated. The voltage generated is proportional to the strength of the magnetic field detected. The switch is available in multiple sensitivity settings to suit specific applications. The device is available in both normally open and normally closed configurations, allowing it to be used with a variety of control systems. The switch is also capable of operating in both AC and DC signals.

The A1123ELHLX-T switch is a small, easy to install device that can be used in a wide variety of applications. It is suitable for use in harsh and/or hazardous environments, including those that involve extreme temperatures or corrosive atmospheres. It is also able to robustly detect magnetic fields in the presence of EMI (electro-magnetic interference) and has a wide operating temperature range (-40°C to 85°C). The device is also resistant to shock and vibration, making it suitable for a variety of industrial and commercial applications.

In summary, the A1123ELHLX-T solid state switch is a magnetically activated switch that can be used for a wide range of sensing applications. It is designed for use in harsh and hazardous environments, and operates on both AC and DC signals. The device is also highly resistant to shock and vibration, making it suitable for use in industrial and commercial applications that require reliable sensing and switch performance.
