Signal relays are essential components in many types of electronic systems and devices. They are designed to control the flow of electricity for a wide range of applications, from motor control to data transmission and computing. 3SBH1142A2 is one of the signal relays series manufactured by AutomationDirect. With low power consumption and up to 2 amps current rating, this signal relay is ideal for various applications.

Application Field

3SBH1142A2 signal relays are available in three different versions, and each has a different power rating. The basic version (3SBH1142A2) is suitable for light duty applications, and can switch currents up to 2 Amps maximum. The robust version (3SBH1142A2K) is designed for heavy duty industrial applications and is able to control currents up to 5 Amps. The low leakage model (3SBH1142A2L) is designed for applications where low leakage is important and can switch currents up to 2 Amps.

This signal relay series can be used in a variety of applications, including automotive, industrial, consumer, and military applications. Its small form factor, low power consumption, and up to 2 Amps current rating make it ideal for a variety of applications. Some typical applications are lighting control, motor control, power distribution, and data transmission.

Working Principle

The 3SBH1142A2 signal relays feature a single pole double throw (SPDT) contact arrangement, which is the most commonly used contact arrangement for signal relays. The internal structure of the relay consists of a coil, a set of switch contacts, and a spring. When an electrical current passes through the coil, it generates a magnetic field that activates the switch contacts, opening or closing them depending on the direction of the current. The spring is then used to reset the contacts after the current is removed.

The contact arrangement of the 3SBH1142A2 also provides a way to control the current rating of the relay. When the contact is open, the current is limited to the 2A rating of the relay, which prevents any overloads or unexpected current jumps. When the contact is closed, the current is limited to the rating of the contact, which can be up to 5A.

The 3SBH1142A2 signal relay series is designed to be highly reliable and provide a very low contact resistance. Due to its low power consumption and small form factor, this signal relay series can fit in even the most compact electronic systems. Additionally, it is designed to withstand high vibration and shock, making it suitable for applications with harsh operating conditions.
