Hongfa Europe GMBH PCB Power Relay 12V DC Coil, 5A Switching Current, SPST, Compact PCB Mount HF46F/5-HS1F(610)

Hongfa Europe GMBH HF46F/5-HS1F(610) PCB power relay is a sub-miniature, intermediate power relay designed for reliable switching performance in industrial, automotive, and electronic applications. Featuring a 12V DC coil and a 5A switching current capability, it offers robust control for a range of low-power circuits. Its SPST contact configuration facilitates straightforward switching of single circuits, making it suitable for control interfaces in automation systems and signal routing within PCB assemblies.

The relay is constructed with silver alloy contacts, ensuring long-lasting durability and maintaining a low contact resistance of just 100mΩ for stable operation. The compact dimensions (15.3mm height, 20.5mm length, 7mm width) make it ideal for densely populated PCB layouts and space-constrained installations. The coil resistance is rated at 720Ω with a coil power of 200mW, optimizing the balance between efficiency and response time.

It offers a wide working temperature range from -40°C up to 85°C, facilitating deployment in environments prone to extreme thermal variation, such as automotive engine compartments, telecommunication equipment, household appliances, and industrial machinery. With a maximum switching DC voltage of 30V and AC voltage of 30V, the relay can safely operate in a variety of control logic and load switching scenarios.

Benefits include high power switching capability - up to 150W for DC - 10kV isolation between coil and contacts, and an endurance of up to 5 million cycles for reliable, long-term service. Environmental compliance is assured by RoHS certification.
