Magnetic proximity sensors use the Hall Effect to detect things without the need for physical contact. This includes identifying magnetic objects or monitoring movement and proximity. They can also be used for non-contact object detection where the normal limits of inductive sensors have been exceeded.

As tools, they can be key for maintaining safety in a variety of industries, while still allowing workers to gain valuable insight.  This means that they can be important when it comes to workplaces complying with the Occupational Safety and Health Administration.

Key benefits include the fact their long sensing ranges. Plus, they can detect stainless steel, aluminium and non-ferrous metal (metals that don’t contain a large amount of iron), as well as non-metal materials such as plastic and wood.

The versatility of magnetic proximity sensors means that they can be applied across a range of industries. Here are some examples:

Automotive industry

Brake control systems commonly require the use of magnetic proximity sensors in the automotive industry. On top of this, RPM sensing and position sensing can be done by mechanics using this as a tool, which helps to prevent accidents from occurring by preventing mechanics from having to reach awkward spaces. It also means that parts of the car don’t have to be taken apart, as the sensor allows conclusions to be made without contact.

Manufacturing and material handling

The manufacturing industry can be diverse – and so too can the applications of magnetic proximity sensors in this field. For instance, it can be used for conveyor belt monitoring, packing machines or to detect the proximity of something when dealing with material. Detection of level is another helpful application of magnetic proximity sensors. Position-sensing robots can also use this technology to improve productivity in the workplace and reduce the risks that workers could be exposed to on the factory floor. Not only can productivity be increased, but warehouse safety can be maintained by preventing collisions and precise positioning.

Security and access control

Security is becoming an increasingly important factor for many Americans to consider. Revenue in the Security segment is expected to show an annual growth rate of 10.54%, which would result in a projected market volume of US$9.14bn by 2027. But did you know that magnetic proximity sensors are a crucial part of the evolving technology in this space? They are used in door and window monitoring so that they can detect the presence or absence of magnets, therefore triggering alarms when necessary.

Industrial automation and machinery

Industrial settings regularly make use of this technology. It can be used for automation and machinery in this space to help. Similarly to in manufacturing, it can be used to sense positions, monitor speeds and detect components. As a result, precise measurements can be made and safety can be maintained, with workers being able to keep a safe distance while taking these measurements. It can also help ensure that machinery is functioning safely and effectively.
