EE2-5NU NEC Relay General Rohs

Review NEC Piece Lot Relay General Purpose Dpdt 2a 5v Rohs

The NEC EE2-5NU 27-Relay is a versatile and robust electromechanical switching device designed to handle general-purpose applications requiring up to 27 isolated contacts. Each relay in this series is rated for a 2 A maximum current and a low operating voltage of 5V DC. This makes them ideal for use in various automation, control, and monitoring systems.

Crafted to adhere to the Restriction of Hazardous Substances (RoHS) directive, these relays are manufactured without the use of lead (Pb) or other heavy metals, contributing to a more sustainable and eco-friendly design. The gold plated contacts ensure a reliable and long-lasting contact performance, while the coefficient of variation (CV) of the contact resistance is kept below 20%, further guaranteeing optimal operational efficiency.

The NEC EE2-5NU 27-Relay offers 27 normally-open contacts, making it well-suited for a multitude of applications where single pole, double throw (SPDT) switches are required. These relays come with an operating temperature range of -30 C to 70 C, enhancing their adaptability and reliability in various environmental conditions. Moreover, the fast switching times and recovery times make these relays an excellent choice for applications where quick response is crucial.

The contacts are made from silver, ensuring good conductivity and durability. The EE2-5NU relays have a low power consumption of less than 20mA when coils are energized. In addition, they come with a built-in overload protection feature, preventing potential damage to the relay from excessive current passing through the coil.

Finally, the NEC EE2-5NU 27-Relay meets the rigorous requirements of international safety standards including UL Recognized, CE, and RoHS, ensuring a high level of quality, safety, and compliance. With their dependable performance, broad range of applications, and eco-friendly design, these relays are an excellent choice for your upcoming projects or system upgrades.

1. Normally Closed (NC) contact type

2. RoHS compliant

3. 27-channel relay in a single package

4. Maximum current rating of 2 A

5. Operating voltage of 5 V

6. Minimum contact rating of 100 mOhms

7. Operating temperature range of -25 C to 70 C

8. Silent switching operation

9. Long contact life

1. Energy efficiency: TheRoHScompliant design reduces toxic substances in the manufacturing process, making it eco-friendly.

2. Space Savings: With 27 channels in a single package, this relay can save space in applications that require multiple relays.

3. Simplified Wiring: Fewer components mean less wiring and easier installation.

4. Improved Performance: Long contact life and silent operation contribute to better performance and reliability.

1. Limited Applications: Due to its high channel count and specifications, this relay might be more expensive and overkill for simpler applications.

1. Variety of contact types (NO, NC, and NC-NO)

2. RoHS compliant

3. Wide range of available channel counts

4. Maximum current rating of 2 A

5. Operating voltage of 5 V

1. Versatility: With a wide range of available channel counts and different contact types, these relays can accommodate various application needs.

1. More complex installation: Having multiple relays instead of a single multi-channel solution may require more components, wiring, and installation time.

2. Higher Cost: Depending on the required channel count, using multiple general relays instead of a single multi-channel solution can be more expensive.

If you have a specific application that requires exactly 27 relays, the NEC EE2-5NU 27-relay might be your best choice due to its space-saving design and simplified wiring. However, if you require a more flexible option or if your application demands a different contact type, a set of general 2A 5V ROHS relays might be a better fit.

Consider evaluating your application requirements carefully, such as the number of channels needed and the desired contact types, before deciding between the two options. Additionally, comparison shop between different manufacturers to find the best price and value for your project.
