SH04.22-A

The EEC SH04.22-A P/N Mini Relay is a compact and versatile 120V AC electromechanical relay designed for various automation and control applications. This No-Normally-Closed (N.O., NORMALLY OEN) type relay is perfect for implementing logic functions in circuits and systems where minimal space is available.

Constructed with high-quality materials, the relay body is made of Dura-Plast material, ensuring excellent durability and withstanding harsh environments. Its contact rating is 2 A at 125V AC, suitable for low to medium power loads. The contact resistance is 15 milliohms maximum at 25 degrees centigrade.

This mini relay features a 1-form A latching mechanism, allowing the contacts to remain in their last position until the coil voltage is applied again for the opposite polarization. The coil requires 120V AC, and the relay has an operating current of 21.3 mA at a nominal voltage of 60 Hz and 230V AC.

The mini relay's no-normally-closed construction is essential in various applications where you want to turn off a load when a specific control input is triggered. An ideal example is an alarm system or a solenoid valve that needs to be closed once the set condition is met.

Using the EEC SH04.22-A P/N Mini Relay, you can easily design and build various control circuits and automation projects with ease due to its compact form factor and reliable performance. Despite its small size, the relay delivers solid and stable contacts ensuring long service life, making it a practical choice for engineers, hobbyists, and system integrators seeking to enhance their circuits or invent new projects.

Pros and Cons of Buying EEC SH04.22-A Mini Relay (120V Coil, Normally Open, Normally Closed)

The EEC SH04.22-A mini relay is a electromechanical switch used to control electrical circuits. Here are the pros and cons of purchasing this particular relay model:

1. Compact Size: With dimensions of 18.5mm x 15.3mm x 6.5mm, this relay is significantly smaller in size compared to standard relays, making it an excellent choice for space-constrained applications.

2. High Switching Capacity: It can handle a maximum working voltage of 120V AC or DC, and a maximum current of 5A, making it suitable for various electrical designs.

3. Normally Open and Normally Closed Contacts: This dual-functionality allows for greater flexibility in circuit design and control.

4. Quiet Operation: The EEC SH04.22-A relay has a low operation sound level (approximately 25dB), which is perfect for applications where audible noise must be minimized.

1. Complex wiring: Due to its normally open and normally closed features, wiring can be quite intricate, especially for those without extensive electrical knowledge.

2. Fragile Contacts: Mini relays often have smaller contacts, which may be more susceptible to wear and tear than their larger counterparts.

3. Limitations with High Current or Voltage: If your application requires high electrical demands, consider purchasing a larger relay that can handle the increased load.

The EEC SH04.22-A mini relay offers significant advantages such as compact size, high burst capacity, and dual functionality. However, it might not be your best choice if you are working with high currents or voltages, or if your design requirements include an easy-to-wire solution. Carefully assess your specific use case to determine whether the pros outweigh the cons for this mini relay model.

If the specific requirements of your project match the capabilities of the EEC SH04.22-A mini relay, it can be a reliable and efficient solution. However, consider consulting an experienced electrical engineer or technician if you are uncertain about the design and wiring complexities. If additional current carrying capacity is needed, consider a larger relay or a solid-state relay for a more robust and long-lasting solution.
