Hydraulic Pressure Switch SG307 Series | SG307F-350 | SG307-F-V2-150 | SG307-F-V2-AS-H2

SG307 Series Industrial Hydraulic Pressure Switches

Product Overview:

The SG307 Series Pressure Switch is an electro-hydraulic component that converts hydraulic pressure into an electrical signal by opening or closing electrical contacts. Utilizing a high-sensitivity plunger structure, internal microswitches are activated when system pressure reaches a preset value, triggering signals to shift solenoid valves, drive actuators, or provide safety interlocks. From the high-pressure SG307F-350 to the specialized SG307-F-V2-AS-H2, this series offers high adjustment precision, minimal repeatability error, and robust vibration resistance—ideal for machine tools, hydraulic power units, and automated production lines.

Featured models include: SG307F-350, SG307-F-V2-150, SG307-F-V2-AS-H2-55, and SG307-F-V2.

Key Technical Advantages:

• High Precision Adjustment: Features premium springs and plunger designs for smooth pressure setting and long-term stability with minimal hysteresis.

• Excellent Pressure Tolerance: Capable of withstanding instantaneous pressure spikes up to 350 Bar, suitable for heavy-duty hydraulic monitoring.

• Modular Interface Design: The V2 and AS-H2 suffixes denote diverse mounting interfaces (e.g., subplate mounting) and electrical connections (DIN plugs or leads), ensuring seamless OEM replacement.

• Rapid Response Time: Equipped with industrial-grade microswitches for high-frequency operation and immediate feedback, securing the integrity of system safety logics.
