Signal Relays provide a number of unique advantages, including low power consumption, high performance, and cost-effective control of signals. They are used in various applications, from industrial and automotive to medical and communication. The TQ4-4.5V-3 is one such signal relay, which is especially designed for use in applications that require precise, low current, and fast switching, and with robust performance.

TQ4-4.5V-3 Application Field

The TQ4-4.5V-3 is a single-pole, double throw (SPDT) signal relay, capable of switching up to 2 amperes. It is suitable for a wide variety of applications, such as industrial automation, home and commercial appliances, automotive, and communications systems. In particular, it is used in systems that require stable control of signals, including vehicular powertrain systems, water treatment systems, air conditioning systems, and home control systems. Also, it can be used in AC switching and monitoring applications, such as data acquisition, and distributed control systems.

TQ4-4.5V-3 Working Principle

The TQ4-4.5V-3 signal relay consists of a main switch, a secondary switch, and a contact group. The main switch is an electromechanical device that is activated by an electromagnet when a current is applied. When the current is applied, the main switch closes, and the secondary switch opens. As a result, the signal from the primary contact travels to the secondary contact, and the current can flow to the downstream devices. The TQ4-4.5V-3 is designed to have a fast switching speed, and can switch low current signals in about 1 milliseconds.

The contact group of the TQ4-4.5V-3 consists of a pair of gold-plated, stainless-steel contacts. Since gold is an excellent electrical conductor, it ensures low contact resistance, and thus, stable switching performance and repeatable switching accuracy. Moreover, since the contact points are made of stainless steel, they are highly resistant to corrosion and wear, providing long service life. Furthermore, this relay is designed to meet a wide range of specifications, including UL, IEC, RoHS, and CE standards.

TQ4-4.5V-3 Key Features and Benefits

The TQ4-4.5V-3 signal relay offers several features that make it suitable for many high-demand applications:

• Low power consumption: Despite its low power requirements, the TQ4-4.5V-3 is able to switch up to 2 amperes, making it suitable for use in a wide variety of systems.
