Power Relays, Over 2 Amps - G4Q-212S DC12 application field and working principle

Relays are devices used to control and trigger electric power operations. The G4Q-212S DC12 Relay is a highly efficient and reliable electromagnetic Power Relay, designed for managing and controlling operations of electrical circuits which require high-performance switches with 2+ Amps. It offers a range of applications and can be used in a variety of applications, including automotive, aerospace and industrial use.

Design

The G4Q-212S Relay is designed with an internal construction which consists of two separate components; the switch contact and the main body. The switch contact consists of a static contact arm and a flex arm which interacts with the contact arm when the coil is activated by an energising current. The main body of the G4Q-212S is constructed from a dielectric plastic and contains all of the necessary components necessary for the relay to work, such as the coil, contact arm, flex arm, and other associated components. The overall design of the relay is compact, lightweight, and robust.

Specifications

The G4Q-212S has the following specifications: * Voltage Range: DC12* Current Rating: 2+ Amps* Contact Material: Silver Alloy* Contact Design: Single Pole Single Throw (SPST)* Coil Resistance: 240 ohms ± 10%* Power Consumption: 50mW* Operating Temperature Range: -40 to +85°C* Operating Time: 15ms* Dimensions: 132 x 33 x 34 mm

Working principle

The G4Q-212S Relay works on the principle of electromagnetic induction. When a current passes through the coil, a magnetic field is created which causes the flex contact arm to move and activate the switch contact arm. When the switch contact arm is engaged, electrical current flows through the contact arm which triggers the power operation associated with the electrical circuit. The G4Q-212S offers low resistance switching with minimal contact sparking and no temperature dependence. The design ensures a low power consumption with small activation times. The contact material of silver alloy allows for high electrical conductivity and resistance which prolongs the overall life of the relay.

Applications

The G4Q-212S is widely used in a variety of applications, including automobiles, aerospace, industrial, and other associated applications. It can be used for controlling low voltage applications and motor control circuits, as well as triggering electrical functions for the auto industry, including acceleration, braking, and lighting. The G4Q-212S is also used for controlling electrical functions in harsh environments such as aero engines, space applications, and high vibration areas. The G4Q-212S Relay offers high efficiency and reliability which makes it suitable for a wide range of applications. It is a highly reliable and efficient power relay which is designed to provide long-term reliability and performance in any setting.
