Ferrous Sensor
SHR’s Ferrous Proximity Sensors are designed to use back-biased reed switch technology, a non-contacting method that allows them to detect the presence of ferrous targets without making physical contact.
One of the most significant advantages of these sensors is that they do not have any moving external components, making them highly resistant to wear and tear. This feature makes them ideal for use in harsh environments, where other types of sensors may be prone to damage or malfunction.
Another significant advantage of these sensors is their low power consumption in standby mode. Since they are not in use all the time, they do not consume power when they are idle, which helps to conserve energy and prolong battery life in applications that rely on battery power.
Overall, SHR’s Ferrous Proximity Sensors offer a reliable and efficient solution for detecting the presence of ferrous targets in a wide range of applications. Their non-contacting technology, durability, and low power consumption make them a popular choice for use in various industries.

Reed switch type ferrous proximity sensors, also known as magnetic proximity sensors, have several advantages over other types of sensors:
- Non-contact sensing: Reed switch type ferrous proximity sensors do not require physical contact with the target object, which means they can detect objects without any wear and tear.
- High durability: Reed switch type ferrous proximity sensors have a long lifespan due to their robust construction and lack of moving parts.
- High sensitivity: Reed switch type ferrous proximity sensors are highly sensitive and can detect very small changes in magnetic fields, making them ideal for use in applications where precise detection is necessary.
- Low power consumption: Reed switch type ferrous proximity sensors require very little power to operate, making them ideal for use in battery-powered applications.
- Simple to use: Reed switch type ferrous proximity sensors are easy to install and use, requiring little to no maintenance.
Overall, the advantages of reed switch type ferrous proximity sensors make them a reliable and cost-effective solution for many industrial and consumer applications where the detection of magnetic fields is necessary.
