Signal relays are electrical components used in countless applications, ranging from household appliances and consumer electronics to industrial applications. The 3SAT1357A2 is a signal relay specifically designed for applications that require high reliability, low power current switching up to two amperes in outdoor environments. This article will discuss the application field and working principle of 3SAT1357A2.

The 3SAT1357A2 signal relay can be used in a variety of settings, including automotive, communication, medical, and industrial applications. This signal relay is designed to switch current in the range of 0.5 – 2A at 24V, making it an ideal choice for applications that require high reliability, low power current switching in an outdoor environment. It is also suitable for use in medical devices, as it meets the relevant safety standards.

The 3SAT1357A2 signal relay is constructed with a stainless steel outer casing and high-grade plastic inner casing that is UL94V-0 flame retardant. This makes it resistant to extreme temperatures and humidity. The design also includes a dust and water resistance coating that protects it from environmental contaminants. Additionally, the signal relay has a low impedance path, which minimizes power consumption and reduces the inductive load associated with current switching.

The working principle of the 3SAT1357A2 signal relay is based on the operation of a reed switch. Two flat pieces of metal that are magnetically charged are placed in close proximity to each other. When an electric current passes through the two metal pieces, a magnetic field is generated which opens the two pieces. The closing of the two pieces when the electric current is removed is referred to as the contact bounce. This action creates a series of on and off electric pulses that trigger the relay to switch.

The 3SAT1357A2 signal relay is an excellent choice for applications that require reliable, low power current switching in an outdoor environment. It is constructed with a durable and resistant stainless steel and plastic outer casing and is designed to switch current up to 2A at 24V. Furthermore, its working principle is based on the reliable operation of a reed switch, allowing the signal relay to switch with minimal power consumption.
