3313A12 NORDIC Sensitive Relay

Review NORDIC Current Sensitive Relay

The Nordic 3313A12 Sensitive Relay is a versatile and reliable electronic component designed for various applications where precise control of low current circuits is necessary. Manufactured by Nordic Normex, this relay offers exceptional sensitivity and stability, making it an excellent choice for handling small signals.

This relays' control voltage range extends from 2.5 to 5 volts DC, enabling it to interface seamlessly with a wide array of microcontrollers and other low-voltage systems. The sensitive coil design ensures that it responds effectively to even the smallest input signals, resulting in accurate relay operation.

The Nordic 3313A12 is a single-pole, double-throw relay, which means that it can switch two different circuits with just one input signal. It also features a built-in diode across the coil, providing reverse current protection against inductive loads. However, if the load is inductive, an external snubber circuit may be required to minimize noise and ensure proper relay operation.

Measuring 28.5mm x 16mm x 8mm (LxWxH), the compact size of the Nordic 3313A12 makes it suitable for space-constraint applications. Its PCB mounting design allows for easy integration on printed circuit boards. The relay operates at a temperature range of -20 C to 70 C, ensuring stable performance under various environmental conditions.

The Nordic 3313A12 is designed to meet the highest standards of electrical performance. Its contact rating is 250VAC/1A or 30VDC/5A, ensuring reliable switching and long-term use. Its switching noise (1/3 wave RMS) is less than 10dBA, making it suitable for applications where low noise is essential.

This sensitive relay comes with a soft-touch mechanism that ensures gentle contact closure between the contacts, minimizing the risk of damages due to arcing and sparking. This feature also makes it a perfect choice for controlling sensitive electronic components.

Please note that proper application and installation of the Nordic 3313A12 Sensitive Relay require an understanding of the specific requirements of the intended application. Always refer to the datasheet and application guidelines provided by Nordic Normex for optimal performance.

The Nordic 3313A12 Sensitive Relay is a commonly used electromechanical switching device that provides a reliable solution for low volume applications with precise switching requirements. Here are some potential pros and cons of buying this relay:

1. High Reliability: Nordic relays are known for their durability and long service life, making them a reliable choice for various applications, especially those requiring precise and consistent switching operations.

2. Compact Size: The Nordic 3313A12 is a compact device, making it easy to install in tight spaces and portable applications. Its small size allows for multiple relays to be mounted on a single PCB, reducing the overall size of the system.

3. Low Power Consumption: This relay features a low power consumption, making it an ideal choice for battery-powered applications or systems where power conservation is important.

4. High Switching Frequency: The Nordic 3313A12 can handle high switching frequencies, making it suitable for applications where fast relay activation is necessary.

5. Versatile Operating Voltage: The relay can operate on a wide range of voltages (5V to 250V DC), making it a flexible solution for various applications.

1. Limited Load Capacity: The Nordic 3313A12 is designed for low load applications, with a maximum load capacity of 50 VA at 250V AC or 25 W at 100V DC. If your application requires switching higher loads, a more powerful relay may be necessary.

2. Manual Controllability: This relay does not have built-in electronic protection circuits, meaning it relies on external components for protection against overvoltage, overcurrent, or short circuits. Manual control of the relay adds complexity to your system design.

3. Potential for Mechanical Noise: As a mechanical device, relays can produce noise when activating or deactivating, which may impact the performance of sensitive electronic systems and cause interference.

4. Limited Lifecycle Testing: Unlike solid-state relays, there is limited lifecycle testing information available for electromechanical relays like the Nordic 3313A12. Without reliable testing data, it can be challenging to predict the relay's expected lifetime in your specific application.

In conclusion, the Nordic 3313A12 Sensitive Relay provides a reliable and compact solution for low volume applications requiring precise and consistent switching operations. However, its limited load capacity, potential for mechanical noise, lack of built-in protection circuits, and limited lifecycle testing data are important considerations. By evaluating these factors in the context of your specific application, you can determine whether the benefits of this relay outweigh the drawbacks or if an alternative relay type would be more suitable.

If your application requires low load switching with precise control, small size, and low power consumption, the Nordic 3313A12 Sensitive Relay could be an excellent choice. However, it is essential to monitor the relay closely to ensure its performance remains consistent and to mitigate any potential issues related to mechanical noise or the lack of built-in protection circuits. For applications with higher load requirements, consider a more powerful relay with the necessary protection circuits built-in.
