Signal Relays, typically designed to control low-power electrical equipment, are electromechanical relays that offer both isolated and non-isolated switching. The UA2-4.5SNU signal relay is a versatile relay designed for up to 2 amperes switching of resistive load with a typical voltage rating of 4.5 volts. Its features and working principle make it ideal for use in a variety of applications—ranging from automotive industries to communications and consumer applications.

Characteristics of UA2-4.5SNU Signal Relay

The UA2-4.5SNU signal relay is designed to control low-power electrical equipment and is capable of switching up to 2 amps. It has a typical voltage rating of 4.5 volts and can operate in temperatures ranging from -20 degree to +80 degree Celsius. It has a standard relay coil and is rated to 10,000 operations at rated load. The relay contact has a rated temperature of -20 degree C to + 70 degree C and a rated insulation resistance of 100mΩ minimum. Additionally, it has a short-circuit capacity of 30V and a break downtime of 2ms (max).

Working Principle of UA2-4.5SNU Signal Relay

The UA2-4.5SNU signal relay is designed to switch electrical circuits in response to an electrical input signal. When the input signal is switched on, the relay coil is energized, which causes a switch to be moved. Depending on the type of relay, it can either make or break a connection in the circuit it is controlling. A make contact closes an external circuit, while a break contact opens it.

The UA2-4.5SNU signal relay is a hermetically sealed unit, which helps to ensure that its working environment is free of moisture, dust, and other contaminants. This helps to ensure reliable operation and long-term reliability. The UA2-4.5SNU also features a normally closed contact configuration, which helps to prevent the relay from losing the set position due to temperature or vibration.

Applications of UA2-4.5SNU Signal Relay

The UA2-4.5SNU signal relay is a versatile device that can be used in a range of applications. From controlling low-power electrical equipment in the automotive industry to communications and consumer applications, the UA2-4.5SNU signal relay can help ensure reliability and long-term operation. Its high insulation resistance, low switching power, and low contact resistance helps provide reliable operation even when exposed to shock, vibration, and extreme temperatures.

The UA2-4.5SNU signal relay is also suitable for use in telecom, electric power, industrial control and other sectors. With its wide voltage range, it can be used in many DC and AC circuits. It also features a high current capacity, enabling it to be used for a wide range of applications.

Conclusion

The UA2-4.5SNU signal relay is a versatile relay designed for up to 2 amperes switching of resistive load with a typical voltage rating of 4.5 volts. It has a wide range of applications, from automotive and consumer applications to telecom and industrial control. Its hermetic sealing, normally closed contact configuration, and wide voltage range help to ensure reliable operation even when exposed to shock, vibration, and extreme temperatures.
