In modern homes, from air conditioners and washing machines to smart lighting systems, the safe and efficient operation of these devices is dependent on one key component - relays. The FANHAR W36, a power relay designed for household appliances and smart homes, has become the ‘invisible guardian’ of many devices thanks to its high reliability, compact design and environmentally friendly features. In this article, we will bring you an in-depth understanding of its core advantages and application scenarios.
1. Strong load capacity
W36 can easily cope with resistive loads of 16A/250VAC, with a maximum switching power of 4000VA, which is stable enough to meet the high-frequency switching needs of both high-power home appliances and smart devices.
2. Environmental and safety certifications
Environmental compliance: RoHS certified, eliminating hazardous substances, in line with the trend of green manufacturing.
Safe and reliable: UL, TUV, COC multiple international certificates, insulation level up to Class F, excellent voltage performance (1000V between contacts).
Excellent voltage performance (1000VAC between contacts, 2500VAC between coil and contacts).
3. Long Life and Fast Response
Ultra-long durability: Mechanical life up to 1,000,000 operations, electrical life up to 50,000 operations under 16A load (switching cycle 1s/9s).
Millisecond response: Suction time ≤10ms, release time ≤5ms, ensuring precise control of the device.
4. Adapt to harsh environment
Wide-temperature operation: supports extreme temperatures from -40°C to 105°C, and stable operation in humid environments (5%~90% humidity).
Anti-interference design: anti-vibration (98m/s²), anti-dust and anti-pollution (optional ‘plastic sealed’ model), no fear of complex installation scenarios.
1. Contact material: AgSnO₂ silver tin oxide
Compared with traditional silver alloy contacts, AgSnO₂ has higher arc resistance and anti-melting ability, especially suitable for frequent switching of high load scenarios, which can significantly extend the service life. 2. compact design, space-saving
2. Compact and space-saving design
Measuring only 23 x 16 x 10mm and weighing approximately 10g, it is optimised for flat surface mounting and suitable for PCB integration.
Available in Flux Proofed and Plastic Sealed packages, the latter being suitable for harsh environments containing hydrogen sulphide and dust.
3. Flexible Adaptation to Multiple Voltages
The coils support a wide range of voltage inputs from DC 3V to 48V, with a power consumption as low as 200mW for high compatibility. For example:
DC 12V model: operating current is only 16.7mA, suitable for low-voltage control circuits in smart homes.
DC 24V model: industrial grade stability, commonly used in central air conditioning or security systems.
1. Smart Home System
Intelligent switch: control the automation start and stop of lights and curtains.
Security equipment: linkage smoke alarms, camera power management.
2. Home appliances
Air conditioner/water heater: Manage the high power flow off and on of compressor or heating element.
Kitchen appliances: timed power switching of microwave oven and oven.
3. Industrial control
Small motor control: e.g. vending machines, conveyor belt devices.
New energy equipment: circuit protection module in solar inverter.
Package type: Flux Proofed for clean environment, Plastic Sealed for polluted environment.
Coil Voltage: DC 3V/5V/6V/9V/12V/24V/48V according to the control circuit voltage.
Special requirements: Special features (e.g. gold-plated contacts) can be customised through the ‘Customer Code’.
In the era of intelligence and environmental protection, Fanfar W36 relays, with their ‘small size, big energy’ characteristics, quietly guard the safety of electricity in thousands of households. Whether upgrading existing equipment or developing innovative products, it is a reliable choice for engineers and consumers.
