UTP28CH120 is a low-power, non-crystalline transverse-magnetic-field (TMR) magnetic switch that enables users to control the magnetic field. It is mainly used in various electrical and electronic applications, such as electromagnetic relays, magnetic filters, magnetic encoders, and magnetic field switches. This article will discuss the application field and working principle of UTP28CH120.

UTP28CH120 is a miniature TMR magnetic switch with an operating area of 40.2 cm2 and a switching power of 20 mW. The size is 10.3mm², and it is capable of controlling 0.1 A current and up to 0.2Tesla magnetic field strength. It has a high ratio of magnetic field strength to power consumption, which makes it a suitable choice for many applications. UTP28CH120 can also be used in applications where temperature range and lifetime are important considerations.

One of the main applications of UTP28CH120 is in electromagnetic motors, relays, and magnetic filters. The switches enable users to control the magnetic fields generated by electromagnets, which are used to actuate mechanical switches. The switch can be used in relays to control the direction of motor current, and also in magnetic filters to reduce RF interference. In both cases, the switch can be used to control the voltage and current in the circuits.

The working principle of UTP28CH120 is based on the transverse-magnetic-field phenomenon. The switch has two loops, a sender loop and a receiver loop. The transmitter loop produces a magnetic field by passing a current through a coil. The magnetic field will induce a current in the receiver loop, which in turn can be used to control the operation of the switch. The magnetic field strength can be modulated by changing the current in the transmitter loop, allowing for a wide range of control options.

In summary, UTP28CH120 is a miniature TMR magnetic switch, suitable to control the magnetic field in a wide range of applications. It is mainly used in electromagnetic motors, relays, and magnetic filters. Its working principle is based on the transverse-magnetic-field phenomenon.
