Key Features
Low Contact Resistance: The contact materials and structure are optimized for small signals, ensuring long-term stable conductivity and reducing signal attenuation.
High Isolation Voltage: High insulation voltage between the coil and contacts effectively prevents signal crosstalk and external interference.
Fast Response: The electromagnetic system design prioritizes operating speed, meeting the timing requirements for fast signal routing and switching in communication equipment.
Long Electrical Life: Provides excellent contact durability under rated load, ensuring the long-term reliability of the equipment.
Main Applications
Communication Equipment: Used for signal switching or power control in network switches, base stations, and other equipment to control the circuit on/off.
Office Equipment and Computer Peripherals: For example, printers, scanners, or UPS power supplies, controlling the start and stop of the main circuit via the relay.
Security Alarm Systems: As a switching element in alarm circuits, responding to control signals to trigger alarms or activate other devices.
Medical Equipment: Utilizes its electrical isolation characteristics to ensure patient and equipment safety, operating stably in diagnostic instruments or monitoring equipment.
Industrial Automation: Some models are suitable for PLC systems or motor control, enabling compact layouts through PCB soldering installation.
