Reed Sensor Market Size, Share, Growth Analysis, By Contact Position (Form A, Form B), By Type (Dry-Reed Sensor, Mercury-Wetted Reed Sensor), By Application, By Region - Industry Forecast 2025-2032

Globally car sales in 2022 reached nearly 66 million units. In automotive sensor applications, reed switches are quite common. The reed switch employs a magnetic float that adapts to the fluid level, in this case for measuring fuel levels, and induces a hermetically sealed switch in the stem. This is increasing the demand for reed sensor in automotive sector. 

Reed sensors are installed in the wind turbines for positioning the blades, yaw control, and other pitch change actuators. They help in specifying the position of the blade and its angle towards the wind direction thus aiding in the optimal performance of the turbine in generating energy. Furthermore, reed sensors are useful for the wind turbine speed measurement which is important for the supervision of the rotor velocity and for controlling the electrical energy developed by the generator. In the photovoltaic sector, reed sensors are used in solar tracking systems to locate the orientation of solar modules in relation to the sun. 

The cost of manufacturing reed sensors is expected to be relatively expensive. Also, the demand for the overall product is also on the higher side. Consequently, the consumption of hall-effect sensors is increasing which in turn is limiting the expansion of the reed sensor market. In addition, unlike reed switches, hall effect sensors are capable of detecting magnetic fields and even their strength and direction. 

Reed sensors, while dependable and adaptable, do not perform well in harsh environments such as in high humid temperatures as well as corrosive environment, and hence have some limitations in terms of durability. Being encased in a glass, they are prone to mechanical impact. Such conditions cause these sensors to fail rendering them inappropriate for use in industrial and outdoor conditions where stronger sensors are needed. Hence, these cannot be broadly used in oil and gas or heavy machinery industries.
