Signal relays are electrical switches used to control an electrical circuit by a low-power signal or current. They are available in very small sizes, which enables them to be used in even the tightest spaces, and in circuits with limited power. The UB2-4.5SNUN-L signal relays, in particular, are specifically designed for applications that require up to two amps of current switching capability.

This signal relay is a magnetically operated, normally open (NO) contact type. It is designed with a small profile, enabling it to be used in the most confined spaces. The smallest of the relay features a 2 mm x 1.5 mm form factor, with the largest offering a 4.5 mm x 1.25 mm form factor. This makes the UB2-4.5SNUN-L a highly reliable option for a range of applications.

The UB2-4.5SNUN-L relay offers a variety of operating temperatures, ranging from -40°C to +85°C. It also has a wide range of DC/AC voltage input options, allowing you to choose the best voltage rating for your application. In addition, the relay is UL recognized, providing a further level of reassurance of high-quality performance.

The internal structure of the UB2-4.5SNUN-L relay consists of a two-piece coil construction: the main coil section and the arch frame. The main section ensures leakage and reduces any electronic interference, while the arch frame provides a stable structure to hold the two-piece coil and ensures that the connection between the components is reliable and secure. Additionally, the relay includes a stainless-steel core stack with a quartz tube shield to protect the switches.

The UB2-4.5SNUN-L has two main working modes: latching and barely-holding. With latching, the relay will hold the contacts in the same position even after the power has been removed. This is useful in situations where you need the contacts to remain in the same position for an extended period of time. In barely-holding mode, the relay will revert to its initial state after the power is removed. This is useful in situations where the contact needs to be changed quickly and frequently.

The UB2-4.5SNUN-L is suitable for a variety of applications, including instrumentation, industrial automation, home appliances, audio, and remote sensing. It is particularly well-suited for applications that require a very low power consumption, a small profile, and high switching accuracy. This, combined with its reliability, makes the UB2-4.5SNUN-L an ideal choice for circuits requiring up to two amps of current switching capability.
