MJN2C-AC120 OMRON Latch Relay Coil

Review OMRON New Latch Relay 120 Coil

The Omron MJN2C-AC120 Latch Relay is a versatile and reliable electrical component designed for various automation applications. This 1-form-A, AC operated latch relay features a 120V AC coil and a 24V DC contact set, making it suitable for use in both low and high voltage systems.

The compact size of this latch relay, measuring only 44.5mm (W) x 36.5mm (H) x 25.5mm (D), makes it an excellent choice for space-constrained installations. Its robust design ensures that it can withstand the rigors of industrial environments, as it is constructed with high-quality components and materials.

The MJN2C-AC120 Latch Relay operates on the latching principle, meaning that it remains in the last position it was switched to, even when the power is turned off. This feature is particularly useful in applications where it is necessary to maintain a specific state in the absence of power.

The relay contacts are rated for a current capacity of 1A at 250V AC or DC, and 0.5A at 600V AC. This makes it suitable for use with various types of loads, such as solenoids, motors, and lights. The relay can handle a maximum power consumption of 3W, making it an efficient solution for low power applications.

The Omron MJN2C-AC120 Latch Relay is designed with ease of use in mind. It features a clear, visible indicator that shows the status of the relay, allowing users to quickly and easily check the current state of the device. The relay also comes with a convenient mounting plate, which allows it to be securely mounted to a DIN rail or a panel.

In summary, the Omron MJN2C-AC120 Latch Relay is a high-performance, versatile, and reliable electrical component that is suitable for a wide range of automation applications. Its compact size, robust construction, and ease of use make it an excellent choice for industrial, commercial, and residential installations.

The Omron MJN2C-AC120 Latch Relay is a commonly used electromechanical device for controlling electrical circuits. Here are some pros and cons of buying this particular model:

1. Latching Function: This relay provides a latching function, which means that once the contact is closed by applying power to the coil, it stays closed even after the power is turned off. This feature is useful in applications where the contact needs to remain in the closed position even when the power is not applied.

2. Compact Size: The Omron MJN2C-AC120 Latch Relay is relatively small in size, making it ideal for use in confined spaces or applications where space is a concern.

3. Normally Open or Normally Closed Contacts: The relay comes with both normally open (NO) and normally closed (NC) contacts, providing flexibility in design and application.

4. AC Operated: The relay is designed to operate on AC power, making it suitable for use in various industrial applications where AC power is available.

5. Robust Construction: The relay is built with high-quality materials, ensuring durability and reliability in harsh operating environments.

1. Limited Coil Current: The coil of the Omron MJN2C-AC120 Latch Relay can only handle a maximum current of 120mA at 12V DC or 24V AC. If the application requires a higher current, a different relay model with a larger coil should be considered.

2. Limited Operating Temperature: The relay is designed to operate in temperatures between -20 C to 60 C. If the operating temperature of the application falls outside this range, a different relay model with a wider temperature range should be considered.

3. Requires External Coil: Since this is a latching relay, an external coil is required to keep the contacts closed. This adds to the complexity and cost of the overall system.

The Omron MJN2C-AC120 Latch Relay is a versatile and reliable electromechanical component suitable for various industrial applications. Its compact size, latching function, and availability of both NO and NC contacts make it an attractive option. However, its limited coil current and operating temperature range may make it unsuitable for some applications.

If the requirements of the application match the capabilities of the Omron MJN2C-AC120 Latch Relay, then it can be a good choice for controlling electrical circuits. However, if the application requires a higher current or wider temperature range, alternative relay models should be considered. It is essential to carefully evaluate the specifications of the relay and the requirements of the application before making a purchase decision.
