Product Description
HED Series High-Efficiency Piston-Type Pressure Switches
Product Overview: The HED series consists of precision piston-type pressure switches engineered for the rigorous monitoring of industrial hydraulic systems. These components detect pressure changes within a circuit and trigger an electrical signal once a pre-set threshold is reached. Featuring an optimized piston design, the HED series offers exceptional switching accuracy and an extended mechanical lifespan, capable of withstanding frequent pressure cycles without false signals. They are essential for automatic cycles, system protection, and sequence control of hydraulic actuators.
Featured models include: HED40A15B/50Z14L24S, HED8OA20/100K14, and HED80A-20/350K14.
Key Technical Advantages:
High Switching Precision: The finely ground piston structure ensures minimal hysteresis (switching differential) and outstanding repeatability for critical pressure settings.
Extensive Pressure Range: Supports a wide spectrum of monitoring requirements, from low-pressure detection up to 350 bar high-pressure system protection.
Flexible Electrical Connectivity: Available with various connector types (e.g., K14 standard DIN 4-pin or Z14 lead-wire), providing robust sealing and vibration resistance.
Industrial & Mobile Durability: Rugged body construction combined with L24S (24V DC) lamp indicators makes them suitable for both factory automation and heavy-duty mobile machinery.
