Signal Relays Up to 2 Amps

Introduction

UB2-4.5SNU is a signal relay used commonly in signal switching circuits, up to 2 amps. It is a latching relay that uses high voltage to perform switching operations. Its built-in signal circuit offers a wide variety of signal control options including pulse, momentary and controlled on/off switches with low power consumption. It is widely used in vehicle telecommunication, security and industrial automation applications.

Application Field

UB2-4.5SNU is one of the most popular signal relays up to 2 amps widely used in vehicle telecommunication, security and industrial automation applications. Vehicle telecommunication applications include signal switching circuits for mobile phones, navigation systems and satellite communication, while security applications include fire alarms, remote monitoring systems and access control. There are also numerous industrial automation applications such as signal switching circuits for manufacturing production lines and robot control systems.

Working Principle

The working principle of UB2-4.5SNU is based on a latching coil and contact system. The latching coil is a high voltage coil that is activated with an electrical signal. When activated, the coil attracts the contact, which closes the relay. The contact is then latched into the closed position until the coil is deactivated with another electrical signal. This makes the UB2-4.5SNU an ideal choice for applications that require controlled on/off switching with low power consumption. In addition, the built-in signal circuit is able to detect and amplify the input signal, making the UB2-4.5SNU a reliable choice for pulse, momentary and controlled on/off switches. The UB2-4.5SNU also offers better than average lifetime and service life, making it a cost-effective choice for applications that require frequent on/off switching.
