Product Description:
The Bosch Rexroth HEDE 11 A1-1X/100/K41G24/2/V (R901141184) is a cutting-edge pressure switch engineered for precise monitoring and control in hydraulic systems. Leveraging a thin-film measuring cell, this device delivers accurate pressure detection and converts data into reliable electrical switching signals, ensuring optimal system performance.
Key Features & Design:
- High-Pressure Resilience: Rated for max operating pressure up to [X] bar (with specific pressure grades: [Y], [Z], and [W] bar), it withstands extreme conditions with a bursting pressure range ensuring safety margins.
- User-Friendly Adjustment: Two visible adjusting rings simplify switching point calibration, while mechanical interlocks prevent accidental setting changes.
- Durable Construction: Media-contacting components (stainless steel/FKM) resist corrosion from fluids like HL, HLP, and HFC, ensuring long-term reliability.
- Compact & Functional: Features two antivalent switching outputs and status indicators (LEDs for switching/ready signals) in a space-saving design.
- Easy Integration: M-pole A-coded connector enables quick electrical connections.
Technical Advantages:
- Certifications: Compliant with CE, UL, and RoHS standards for global applicability.
- Wide Temperature Range: Operates reliably from -40°C to +100°C.
- Lightweight: Unpacked weight of 0.1321 kg for easy installation in confined spaces.
Applications:
Ideal for industries requiring precision pressure management:
- Industrial machinery (presses, injection molding)
- Construction equipment (excavators, cranes)
- Mobile hydraulics (agricultural vehicles, forklifts)
- Energy sectors (hydropower, offshore platforms)
Why Choose Bosch Rexroth?
- Innovation: Thin-film technology ensures high accuracy (<±1% F.S.) and fast response times.
- Safety: Spring-loaded diaphragm design prevents overpressure damage.
- Reliability: Backed by Bosch Rexroth’s 130+ years of hydraulic expertise.
Considerations:
- Pressure Grade Selection: Match sensor ratings to system requirements.
- Maintenance: Regularly inspect seals and connections for optimal performance.
Conclusion
The HEDE 11 A1-1X/100/K41G24/2/V combines compactness, durability, and precision to meet the most demanding hydraulic monitoring needs. Its CE/UL/RoHS compliance, corrosion-resistant materials, and user-centric design make it a trusted choice for professionals prioritizing safety and efficiency.
