SFS2-L-DC24V-D

Power relays have numerous applications in the industry, ranging from switching heavy electric loads to controlling the HVAC system in cars. This article will discuss the SFS2-L-DC24V-D specifically, which is an over two amps rated general purpose power relay. This article will cover the fields of applications and working principle of this relay.

Fields of Applications

The SFS2-L-DC24V-D is ideal for general-purpose switching applications, such as:

• Automotive applications, like controlling air conditioning, headlights and other electrical components
• Industrial control systems for switching DC voltage
• Motor control applications, such as in pumps, blowers, and motors
• Hotel automation systems

The SFS2-L-DC24V-D is also suitable for high inrush current applications, such as with solenoids and compressors, due to its power rating of more than two amps. It is also a great choice for high temperature applications, with its temperature range of -20°C up to +85°C.

Working Principle

The SFS2-L-DC24V-D works by using a coil current to generate a magnetic field, which activates the contact. The coil is made up of two pieces of wire, which will conduct electric current when supplied with a voltage of up to 24V-DC. This causes two poles to be created, one which contains the magnet and another which contains the contacts. When the switch is triggered, the two poles will be connected, allowing electricity to flow through the switch.

The contact is made up of four tiny pieces of metal, which are connected to the metal strips and the control coil. When the switch is activated, these strips come together, creating an electrical connection that will allow current to flow through the contact. When the switch is off, these strips will separate, blocking the flow of current.

Besides the standard contact types found in most power relays, the SFS2-L-DC24V-D also offers a range of alternative contact types. These include two-contact relays for high-temperature applications, as well as bistable and latching types for small low current applications. Additionally, it also provides dual coil versions for controlling two circuits at the same time.

Conclusion

The SFS2-L-DC24V-D is a general-purpose power relay with a power rating of over two amps, which makes it ideal for various applications like automotive, industrial, and motor control. It works by generating a magnetic field to activate the contact via a DC voltage up to 24V. The contact is made up of four tiny pieces of metal, which will either connect or disconnect the current depending on the switch’s state. The SFS2-L-DC24V-D also provides a range of alternative contact types and dual coil options.
