Magnetic sensors are essential elements in many electronic systems used in aerospace, automotive, industrial, and consumer applications, allowing for the detection and interpretation of various magnetic properties such as position, rotary position, speed, direction, and distance. The EW6672 is a type of magnetic sensor, often referred to as a solid-state switch, specifically designed for use in harsh environments. This article will explore the EW6672’s application field and working principle in detail.

The EW6672 is a unique magnetic switch that can be used in applications where other magnetic sensors may not be suitable. Its core components are an open magnet and two reed switches. This device has an operating temperature range between -50°C and +125°C, making it suitable for use in extreme temperature environments. The EW6672 is accessible in surface-mount (SMT) and through-hole (THT) versions, and it offers the option of customizable magnets for applications requiring different magnetic ranges. This makes the EW6672 ideal for use in moving applications, such as package delivery robots and automated guided vehicles.

The EW6672 works on the basis of the interaction between a magnet and a reed switch. The reed switch is a type of switch that is activated or deactivated by means of a magnetic field. When the magnet is close to the two reed switches, the reed switches will be “closed”, meaning electricity will be able to flow through them. However, when the magnet is no longer in close proximity, the reed switches will be “open” or deactivated, and the electrical flow will be halted.

This magnetic switch also features strong form factors and superior shielding from external interference. Its housing is made of a thin, robust sheet of polymer that is resistant to dust and moisture, making it suitable for use in outdoor or marine environments. Additionally, its magnetic material is embedded inside the housing for extra protection, and its PCB is coated with an insulation material that helps to reduce cross-talk between components. Combined, these features reduce the amount of external interference that could affect performance.

The EW6672 has the following applications: continuous contactor monitoring and replacement, open- or closed-loop sensing of DC motors, position control, speed sensing, and pulse monitoring. Due to its wide operating temperature range and robust housing, it is especially suitable for industrial applications, such as in packaging and production lines in factories.

In summary, the EW6672 is a type of magnetic sensor specifically designed for use in harsh environments. It features a wide operating temperature range, robust housing, strong shielding from external interference, and customizable magnets. The EW6672 works on the basis of an open magnet and two reed switches, and it is suitable for industrial applications such as in packaging and production lines in factories.
