Rexroth Pressure Switch HED80A-20 200K14 Pressure Relays 100% New Original

Rexroth HED80A-20 200K14 Pressure Relays Stability High Safety 100% New Original

• High-precision control and signal stability: Built-in plunger-type mechanical structure and PID closed-loop regulation technology achieve ±0.5% control accuracy. Features high-resolution DAC and multi-channel configuration for synchronous control of multiple proportional valves.
• Pressure protection and mechanical safety: Linkage design with spring seat and damping hole structure buffers pressure impacts. Oil-resistant rubber sealing rings and precision-machined valve body ensure leak resistance and stable high-pressure operation (up to 250Bar).
• Intelligent diagnosis and compatibility: Integrated overcurrent, overheating, and signal abnormality detection with LED indicators and fault codes. Compatible with 24V DC input and Rexroth components.
• Scenario Adaptation Flexibility: Supports safety protection, sequential motion control, hydraulic pump unloading, and more. Ideal for machine tools, injection molding machines, and metallurgical equipment.

• Selection and Installation: Choose model according to system pressure range (HED 8 series supports 250Bar). Ensure proper terminal tightening and use shielded cables to reduce electromagnetic interference.
• Debugging and Maintenance: Calibrate set values using Rexroth software. Regularly check spring preload and micro switch contacts (recommended every 2000 hours).
• Environment and Operation: Avoid high dust or humidity (>90%) environments. Do not use with unclean hydraulic oil to prevent damping hole blockage.
• Storage and Troubleshooting: Apply anti-rust oil for long-term storage. Check sealing rings and terminals first if issues occur before disassembling micro switch.
