AZ943-1CH-5DE AMERICAN ZETTLER General Relay Spdt Coil

Review AMERICAN ZETTLER General Purpose Relay Spdt Form 5vdc Coil

The American Zettler AZ943-1CH-5DE is a single-pole, double-throw (SPDT) general-purpose relay with a coil voltage rating of 5 Volts DC. This versatile component is designed for use in various applications, particularly those requiring the switching of electrical loads.

The compact size of this relay measures 35.5mm in length, 21.6mm in width, and 13.6mm in height, making it suitable for space-constrained designs. The contact rating for this model is 10A at 250V AC or 15A at 60V DC, ensuring it can handle moderate currents and voltages.

The AZ943-1CH-5DE relay comes equipped with a 5mm diameter x 12mm deep coil. This relatively small coil footprint simplifies PCB layout and design, allowing for more efficient use of space. The coil resistance is approximately 250 ohms, which results in an inrush current of around 0.95A when the relay is energized.

The NO (Normally Open) and NC (Normally Closed) contacts on this relay are silver-plated, ensuring good conductivity and long contact life. The contacts are rated for a total of 3,000,000 operations, which makes the AZ943-1CH-5DE a reliable choice for applications that require frequent switching.

This general-purpose relay features a plastic housing and is designed to operate in temperatures between -25 C to 70 C. The contacts are gold-plated to further enhance their durability and performance. The coil is protected by a current-limiting resistor, which safeguards the component from overcurrent conditions.

The AZ943-1CH-5DE is a RoHS compliant component and is suitable for use in various industries, including automotive, telecommunications, medical, and industrial automation. Its compact size, reliable performance, and versatile voltage rating make it a popular choice for designers and engineers seeking a robust and dependable switching solution.

The American Zettler AZ943-1CH-5DE general-purpose SPDT (Single-Pole Double-Throw) relay is a commonly used component in various electronic projects and systems. Here are some pros and cons of buying this specific relay:

1. Widely used: This relay is a popular choice due to its versatility and broad application in various electronic systems.

2. Compact size: Its small form factor makes it suitable for projects with limited space requirements.

3. Low voltage: The 5V DC coil voltage requirement makes it compatible with many popular microcontrollers and power supplies.

4. Reasonable price: The price point is competitive compared to similar relays from other manufacturers.

5. High reliability: Zettler is a reputable manufacturer known for producing high-quality electronic components.

1. Limited current capacity: The maximum current handling capacity is relatively low (1.2 A), which may not be suitable for high-power applications.

2. Manual operation: This relay is not opto-isolated, meaning it requires a direct electrical connection between the control circuit and the relay coil.

3. Potential noise: Relays can generate some electrical noise during operation, which may impact sensitive electronic systems.

In conclusion, the American Zettler AZ943-1CH-5DE general-purpose SPDT relay is a reliable and widely-used component suitable for various electronic projects that require a low-voltage, compact, and affordable relay with a reasonable current handling capacity. However, it may not be the best choice for projects requiring high current handling or opto-isolation.

Recommendation: If your project requires a general-purpose relay with a 5V DC coil voltage, this Zettler relay is a good option to consider. However, make sure to verify that the maximum current requirement of your circuit is within the relay's specifications before making a purchase.
