Introduction

Magnetic sensors are sensors that use magnetism as a means of measuring whatever variable is being sensed. The type of magnetic sensor, as well as the application and working principle, varies depending on the type of sensor. One type of magnetic sensor is the 55140-2H-04-E, which is categorized as a position, proximity, and speed sensor module.

Applicability

The 55140-2H-04-E module is an all-in-one Hall Effect position, proximity, and speed sensor. This device is designed for use in automotive applications as a proportional speed and/or position sensor. It is also used in a variety of control and monitoring applications, such as manufacturing process control, motion control systems, HVAC systems, and robotics.

Design and Specifications

The 55140-2H-04-E module is a compact, integrated module that is designed to withstand harsh environmental conditions and vibration levels. It features a Hall effect output signal with a built-in signal amplifier. The module includes a specialized ferrite-core-based magnetic field generator, which provides a stable and repeatable output signal. The 55140-2H-04-E module also features a selectable gain range of 0.5 to 9.0 mV/G, adjustable pull-up resistor, adjustable hysteresis, and selectable frequency response. The module also features a temperature range of -40°C to 150°C (-40°F to 302°F). It has a voltage range of 4.75 to 16 VDC and a current consumption of 3.6 mA max. The 55140-2H-04-E also has an LED indicator and a RoHS compliant design.

Working Principle

The 55140-2H-04-E module is based on the Hall effect principle, which states that a current carrying conductor in a magnetic field will experience a torque, or force, acting at right angles to both the direction of the current and the direction of the field. In other words, a voltage will be generated across the conductor when there is a change in the magnitude or direction of the field in which the conductor is immersed. The module uses a ferrite-core-based permanent magnet to generate a uniform magnetic field in which the Hall effect sensor is immersed. The sensor senses the change in the magnitude or direction of the magnetic field, and produces a voltage signal proportional to the strength of the field. This signal is used to measure speed or position in various applications.

Conclusion

The 55140-2H-04-E module is a position, proximity, and speed sensor that uses the Hall effect principle to detect changes in the magnitude or direction of a magnetic field. This allows the module to measure speed or position in a wide variety of automotive and industrial applications. The module is designed for high vibration and temperature levels, and has a compact, RoHS compliant design.
