Excellent durability and mountability

The disadvantage of the reed switch is its encapsulation in a tube of glass, a material and structure that make it easily breakable due to its vulnerability to vibrations and shock.

The configuration of the reed switch pins makes it difficult to simultaneously mount it with other components, which prolongs the mounting process.

Advantages of the new S-5701 B Series of TMR sensor ICs:
・The TMR element and the signal processing circuit are mounted and resin molded on the same silicon and are therefore extremely durable.

・Available in a small and thin surface-mounted package, it can also be mounted simultaneously with other components.

The S-5701B Series uses a small TMR element that is 1/10 the size Comparing the size of a TMR element with the size of a regular reed switch.

Magnets and sensors can be downsized

In a reed switch, the magnetic field must affect a major portion of the reeds, which means that the magnet used for detection cannot be shrunk beyond a certain size.

The S-5701B Series uses a small TMR element that is 1/10 the size* of the elements in a comparable reed switch. Small size magnets simplify placement, reduce the size of the final product and improve design friendliness.

Stable, ultra-low current consumption extends operating life - TMR sensor IC S-5701 B

Stable, ultra-low current consumption extends operating life

A reed switch is a magnetic switch that consumes a very small amount of power as current flows only when it is on, but not when it is off.

However, its unstable current consumption is a disadvantage that lowers the reliability of battery operation.

The current consumption of the S-5701B Series is in the nano-level range both when on and off. The new TMR sensor IC provides reliable operation of battery-operated devices.
