Technical Information
Reed Sensor
The reed switch is the major component in any reed sensor, so understanding the characteristics and capabilities of the reed switch is very important in understanding reed sensors. More Detail.
Hall Sensor
Discovered by Edwin Hall in 1897 the "Hall effect" has been around for a long time. It is only since the adoption of semi-conducting materials by the electronics industry in the 1960s that this discovery has moved from an interesting physical effect to one that has found serious practical applications. Today Hall effect technology enables the design of sophisticated sensors used in a wide range of automotive, industrial, consumer product applications. More Detail.
Reed Switch
The basic reed switch consists of two ferromagnetic nickel-iron wires and a glass capsule. The two wires are formed into "reeds" by flattening one end. The reed ends are carefully aligned with a small overlap and then permanently sealed inside the glass capsule. The overlap or contact area of the reeds is coated with special metals such as ruthenium. The nickel-iron leads are tin plated so that they can be soldered. More Detail.
Reed Relays
Compared to other relay technologies, reed relays have the advantages of hermetically sealed contacts, low coil power, fast operation, and small size. However, as with any technology, there are various aspects to consider. More Detail.
Featured Solutions
Industrial and Domestic Utility Metering for Water and Gas
Hamlin sensors are commonly used in these applications where they perform the function of electrically measuring consumption. Reed switch technology is highly suited to these applications as the hermetically sealed switching contacts can operate reliably for decades in harsh conditions. Zero power operation compliments the use of battery powered data transmission.
