液体レベルリレーHHY7シリーズ

Q1: What is the main physical difference between HHY7G and HHY7P models?
HHY7G features a plug-in base for quick Din rail mounting, while HHY7P is a specialized panel mount relay designed for direct installation on control cabinet doors. Both series share the same high-standard internal components for stable automatic liquid level control.

Q2: Can the HHY7 series be used for agricultural irrigation systems?
Yes, these relays are ideal for agricultural irrigation control, providing reliable 380V circuit switching for high-capacity pumps. Their low power consumption and compact size make them a cost-effective solution for large-scale farm water management.

Q3: Do these relays comply with international safety and quality standards?
Our HHY7 series is fully compliant with the GB/T 14048.5 standard, ensuring it meets the rigorous requirements for industrial control gear. For bulk purchasers, this certification guarantees long-term reliability and safety for commercial liquid level sensors used in heavy-duty applications.

Q4: Are HHY7 relays suitable for high-frequency switching environments?
Designed with high-quality electrical endurance, they serve as a reliable floatless level switch that handles frequent cycles without performance degradation. Their stable and durable build reduces maintenance downtime for industrial and agricultural production lines.
