UD2-3SNUN

Signal Relays, Up to 2 Amps

UD2-3SNUN signal relays are a type of electro-mechanical relays used in a variety of applications, including power supplies, alarms, security, and communication systems. These relays provide an efficient and reliable way to switch electric signals, acting as a "conduit" between two points with a low-resistance connection between them. This allows for faster and more reliable operation of any circuit or system, even in low-current conditions.

The UD2-3SNUN relay is capable of carrying up to 2 amps of current, making it suitable for a wide range of applications. It has a contact reliability rating of 10 million cycles, so it is able to withstand repeat use over time without significant deterioration in performance. The UD2-3SNUN has a temperature range of -40 °F to 155°F, meaning it can withstand a wide range of environments without any problem.

The working principle behind the UD2-3SNUN is quite simple. It uses a coil to magnetically trigger a spring-loaded set of contacts that, when closed, connect the two points together. This is the same as in any other relay: the magnetic field created by the coil causes the contacts to move and close the circuit, allowing current to pass. This allows the user to turn an electric signal on and off, control a circuit, or switch between two different points.

The UD2-3SNUN is designed with safety in mind. The contacts are designed to remain closed while current is flowing, and they will open in response to a sudden overload or when triggered by an external command. This prevents damage to the circuit due to sudden changes in current and keeps the circuit from overloading.

The UD2-3SNUN is a versatile and reliable signal relay that can be used in a wide range of applications. With its high current carrying capacity and reliable performance, it is one of the most popular types of signal relays used in the industry. It is an ideal choice for any system that needs a reliable and efficient way to switch electric signals.
