The TXD2SA-L-1.5V-4-Z is a signal relay of up to 2 Amps. It\'s intended use is for switching electrical signals, such as high-current switching of switchable control signals. It has a pin configuration of SPST (Single Pole Single Throw), meaning it has one single pole that can open or close a connection. The relay has 4 pins: COM (common), NC (normally closed), NO (Normally open) and B (power supply).

The power supply of the relay is 1.5V, which means that it will operate only on 1.5V DC power. This feature makes it suitable for a variety of applications, including battery-powered applications and low-power circuit boards. Using the B pin, the relay can be powered either directly from a DC supply or from the board\'s main power supply.

TXD2SA-L-1.5V-4-Z can be used for switching signals of up to 2 amps. This makes it suitable for applications such as circuit breakers, lighting systems, and automotive systems. It is also suitable for applications where a low-contact-resistance is needed. The two contacts of the relay are gold-plated, which provides less contact resistance and a longer lifetime. This is desirable for high-current applications.

In terms of working principle, when the COMMON and NO (normally open) pins are connected to the power supply, the relay is in an "off" state. When the COMMON and NC (normally closed) pins are connected to the power supply, the relay is in an "on" state. This is the basic principle of how the TXD2SA-L-1.5V-4-Z operates.

The TXD2SA-L-1.5V-4-Z signal relay can be used in a variety of applications including switching high-current control signals, circuit breakers, lighting systems, and automotive systems. Its low contact resistance and gold-plated contacts make it suitable for high-current applications. The relay\'s 1.5V power supply requirement makes it suitable for battery-powered and low-power circuit boards. Thanks to its simple working principle, it is easy to use and understand.
