Signal relays are an integral part of communication and industrial systems, offering quick, reliable switching of low-power devices. The TQ4H-L2-4.5V is an advanced signal relay specifically designed for the demanding needs of the automotive industry, providing comprehensive data switching capabilities in a highly accurate, cost-effective package. The relay has a broad range of applications from automotive displays and audio systems to consumer electronics and medical instrumentation.

The TQ4H-L2-4.5V is ideally suited for low-power switching applications, with a contact rating of 28V, 250mA and a maximum switching current of 2 Amps. It can be used for both AC and DC applications up to 4.5 volts with ratings of 60VA or 75VA. The relay has a fast response time of 2.0ms at 50mA with a contact resistance of 30mΩ maximum.

The TQ4H-L2-4.5V is designed to operate at a wide range of temperatures (-55°C–+125°C). It is RoHS compliant and UL listed, making it safe and reliable for use in a variety of applications. The relay is also designed with a low inter-contact leakage current of 1µA, providing high immunity against electromagnetic interference and environmental interferences.

The TQ4H-L2-4.5V is built with a unique design that utilizes two sets of contacts for reliable performance. The first set of contacts (the primary contacts) is connected to the main power source, while the second set of contacts (the auxiliary contacts) is used to control the switching operation. This helps to reduce power loss due to contact resistance and improves the accuracy of the switching operation. The relay\'s design also ensures that the contacts remain clean throughout the switching operation.

In addition, the TQ4H-L2-4.5V uses an automatic reset feature that restores the relay to its original state after a brief interruption in power. This feature increases the reliability and safety of the relay and makes it suitable for use in a wide range of applications.

In conclusion, the TQ4H-L2-4.5V signal relay is a reliable and efficient solution for low-power switching applications. With its wide range of capabilities, fast response time, and high immunity to environmental interferences, it can be used in a variety of industrial, automotive, and medical applications. Its unique design and automatic reset feature make it a safe and reliable choice for any low-power switching application.
