LJR2110A Datasheet/PDFThe LJR2110A is a lead type power relay available in both a standard and enhanced version. It is designed for applications with switching currents of over 2 amps and with a maximum carrying capacity of up to 20 amps.
The LJR2110A is equipped with several features that make it especially suitable for applications such as ambulances and other emergency vehicles where a short on-off switch time is needed. It features a high-power switching capacity of 30V/5A and a semi-permanent contact life of up to 5 million cycles. The device is also highly reliable in switching environments and boasts a vibration-resistant construction.
The LJR2110A relay has two terminals: the Common pole terminal is used to connect the load to the relay; the Normally Open terminal is used to connect power to the relay. The device is designed to facilitate reliable switching of power with minimal current leakage. The isolation between the common pole and normally open pole is designed for optimal performance in environments with high electromagnetic interference.
The LJR2110A uses a DC actuating power of 5 to 24V for its operation. During normal working conditions, the DC actuating power to the coil of the device is held at 5V. When a voltage higher than 5V is applied to the coil, a magnetic field induces a current in the armature which pulls the contact onto the common pole. This causes the Voltage at the Normally Open terminal to be 0V, allowing the load connected to the Common pole to be cut off. The relay is designed to use a low actuating current (<30mA) and consume a low standby current, making it ideal for many applications.
In conclusion, the LJR2110A is a high-power, lead type power relay that is designed for use in applications where a high-power switching capacity and high switching reliability are required. It has a vibration-resistant construction and features a high-power switching capacity of 30V/5A and a semi-permanent contact life of up to 5 million cycles. The device requires a DC actuating power of 5 to 24V and consumes a low actuating current and standby current.
