BST Reed sensor uses the reed switch as the heart of its switching mechanism. When paired with a permanent magnet, reed sensor is perfect for proximity, movement, liquid level application. As a leading reed sensor factory, BST offers reed sensor with different sizes and shapes and hence it's able to meet different applications. Typical reed switch sensor has Normally open, Normally closed and Changeover form, and the rated power can be up to 100W .
Reed sensor works by opening and closing the reed switch contacts in the presence of a magnetic field, when it's in standby status, nearly no power is consumed. Furthermore the reed type sensor will perform billions of operations.
Reed sensors offer versatile and reliable sensing solutions across numerous industries, proving indispensable in modern technology. In telecommunications, they enable seamless pulse dialing, while in security systems, they detect unauthorized access to safeguard assets. The automotive sector benefits from their use in fuel level sensing, tire pressure monitoring, and power window controls, enhancing safety and efficiency. Reed sensors are integral to home appliances, managing fluid levels, water flow, and door mechanisms in devices like washing machines and refrigerators. In medical equipment, they provide precise position control in pumps, hearing aids, and diagnostic tools. Furthermore, their role in renewable energy, such as optimizing wind turbines and solar panel alignment, showcases their contribution to sustainability. These versatile sensors deliver accurate, durable, and cost-effective solutions tailored to diverse applications.
A reed switch sensor is usually a combination of reed switch and magnet. A reed switch is a pair of electrical contacts that contained within a hermetically sealed container, the contacts open and close in the presense of a magnet.
To choose a reed sensor, customers need to understand how a reed switch sensor operates using magnet interaction. Reed sensors work in one of four contact states.
Normally Open (Form A) – The normally open state is where the contacts rest in an open mode. The reed switch consumes no power in the open state.
Normally Closed (Form B) – A normally closed contact state refers to the switch contacts resting in a closed position.
Changeover (Form C) – Changeover occurs when a normally closed contact makes or opens before a normally open contact breaks or closes.
And there is one more contact state, Bistable (Form E) – this is a less frequently used but more advance mode, The methods used depends on the actual application. A permanent magnet is used to change the contact state by reversing the magnetic polarity.
Reed sensors are widely used for proximity, water level, flow rate application, they are ideal for home appliance, automobile, industrial measurement according to customer's needs.
