Product Features:
High Contact Switching Capacity: In addition to the standard 20A load, the contacts support switching up to 35 amps, capable of handling the instantaneous current surges during car starting or from high-power accessories.
Ultra-Low Power Consumption: Coil power consumption is only 0.6W/0.8W, helping to reduce the burden on the vehicle battery and aligning with the automotive industry's trend towards low energy consumption.
Excellent Mechanical Durability: Features high shock and vibration resistance, ensuring stable electrical connections even in bumpy driving conditions and engine vibrations.
Wide Coil Voltage Range: Available in various specifications from 3VDC to 48VDC, adapting to different types of automotive circuit voltages.
Compact Design: Optimized structure and small size facilitate dense installation in confined automotive electrical control boxes.
The CYE (T78) relay is an ultra-miniature high-power electromagnetic relay with a wide range of applications.
Its main uses include:
Automotive Sector: Commonly used in car door lock motor control, car anti-theft alarm systems, and signal switching and load control in automotive electronic equipment.
Home Appliances and Office Equipment: Suitable for power management or signal transmission in household appliances (such as air conditioners, washing machines) and office automation equipment.
Security and Alarm Systems: As a core component of automatic anti-theft alarms, it controls circuit switching.
Industrial Control and Automation: Used in industrial automation systems, instruments, and communication devices to control high-power loads with low-voltage signals.
Consumer Electronics and Emerging Technologies: Extended applications in smart homes, IoT devices, new energy equipment, and medical electronics.
