Magnetic Sensors - Position, Proximity, Speed (Modules) covers a broad range of applications, from automotive to medical and industrial, each with their own specific requirements for performance and reliability. In this article, we will discuss the 55140-2L-01-D and its application field and working principle.

The 55140-2L-01-D from PIL Sensors is a compact, low profile, and lightweight digital electromagnetic position sensor. It is designed to provide reliable and accurate feedback when used in a wide range of applications. The sensor is perfect for applications where space is limited and the environment is constrained, such as automotive and robotics applications.

The sensor uses a unique closed-loop compensator to detect the magnetic field of any ferromagnetic material in its environment. This technique greatly improves accuracy and repeatability, compared to traditional open-loop systems. The sensor is also equipped with a temperature compensation circuit, allowing it to maintain a higher accuracy over a wide range of temperatures.

The 55140-2L-01-D can be used in a variety of applications. It is ideal for angular measurement and position control applications. For example, it can be used to control the steering in a remote-controlled vehicle, or for speed sensing in heavy machinery. The sensor can also be used in medical and industrial applications, such as the control of robotic arms or valves. In addition, the sensor can also be used in anti-lock braking systems, wheel speed sensors, or to measure the displacement of a linear actuator.

The 55140-2L-01-D utilizes a Hall Effect-based sensing device for the magnetic field detection. The sensor uses a bipolar Hall Effect transducer that measures the distortion of a magnetic field from a permanent magnet placed nearby. The response frequency of the sensor is dictated by the strength of the permanent magnet. The sensor outputs an analog voltage, which is proportional to the measured magnetic field.

The 55140-2L-01-D provides a linear output voltage proportional to the physical angle between the magnetic field and the sensing directions. The sensor is accurate up to 0.1° and requires a 5V DC power supply. It is also RoHS compliant and supports a temperature range of -40°C to +85°C.

The 55140-2L-01-D is an ideal solution for applications requiring precise and accurate position sensing in harsh environments. It offers low power consumption at a very attractive price point, which makes it a great choice for many industrial and automotive applications.
