Working Principle of 3SBH1130A2

The 3SBH1130A2 signal relay is designed to reduce power consumption and achieve system cost savings. This is achieved through its unique design and construction. The relay operates by the principle of an electromagnet or solenoid. When a voltage is applied, current flows through the winding of the electromagnet, generating a magnetic field. This magnetic field attracts the relay\'s movable contact, causing it to close the circuit. When the voltage is removed, the magnetic field dissipates, allowing the contact to move back to its original position, opening the circuit.

The 3SBH1130A2 signal relay employs an overmolded construction technique. This overmolded housing capsule seals the relay, providing additional protection against shock and moisture. This method also ensures consistent performance in extreme environmental conditions. The contact is also highly resilient to wear and vibration, allowing for extended service life.

In addition to its unique overmolded construction, the 3SBH1130A2 signal relay features a staggered coil design. This allows it to achieve higher current switching than standard relays. It also features a shorted coil protection circuit, which trips to prevent coil short circuits. This protection circuit is mainly used in applications involving large inrush currents.

Conclusion

The 3SBH1130A2 signal relay is a highly reliable, robust, and power-effective device. Its unique design and construction enable it to perform under high-temperature and vibration conditions. It is designed for various applications, including industrial automation, robotics, electronic controls, telecommunications systems, medical equipment, automotive engines, and military applications. With its ability to switch up to 2 amps of current, the 3SBH1130A2 signal relay offers the highest performance in its class.
