Magnetic sensors are used to measure the position, proximity, or speed of an object, typically within a straight line, but they can also detect when an object moves across its surface, or a change in magnetism. The D40A-1C5 is a position, proximity, and speed module designed for use in applications that require reliable, accurate, and low-power measurement of metal objects.

Features

• Protected to withstand short-term overloads or reverse polarity.
• Rugged construction
• Impervious to dirt, dust, and moisture
• Low power consumption
• Customizable sensitivity (up to 2.5mV)
• Comprehensive temperature compensation range (-40°C to +85°C)
• Low cost, making it suitable for most industrial and commercial applications

Applications

The D40A-1C5 is suitable for a wide range of applications including proximity sensing, object position detection, speed sensing, and position recognition. It is ideal for applications such as motor control (magnetizing and demagnetizing), linear motion, metal object detection, pressure monitoring, proximity sensors, and level sensing. With its low-power consumption and small form factor, the D40A-1C5 is also suitable for applications such as wearables and medical devices.

Working Principle

The D40A-1C5 module works by detecting changes in the magnetic field of a metal object. A permanent magnet is fixed inside the module and a moving metal object will induce a voltage in the module coil. This voltage is then processed by the module’s integrated circuit and can be used to detect the position, proximity, and speed of the object. The module also has adjustable sensitivity settings, allowing it to detect objects at varying distances.

Conclusion

The D40A-1C5 module is an ideal solution for applications requiring reliable, accurate, and low-power magnetic sensing. It is suitable for a wide range of applications, from motor control to wearables, and offers a comprehensive temperature compensation range, rugged construction, low power consumption, and adjustable sensitivity settings.
