Description

The REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416 is a high-precision proportional directional control valve engineered by Bosch Rexroth under its integrated Sun Hydraulics product line. This 4-way, 3-position (closed-center “D” spool) cartridge valve features onboard digital electronics, real-time spool position feedback, and dual-mode signal compatibility (±10 V analog + CANopen), enabling true closed-loop hydraulic control in demanding industrial applications.

As part of the SYHNC100 series—now fully aligned with Bosch Rexroth’s global standards—the REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416 delivers servo-like accuracy with the robustness, serviceability, and cost efficiency expected from industrial proportional hydraulics, making it ideal for presses, test rigs, material handling, and energy-efficient machine designs.

Application Scenarios

At a Tier-1 automotive supplier in Germany, inconsistent forming depth in a hydroforming press led to 8% scrap rates and frequent downtime for recalibration. The root cause was drift in older open-loop proportional valves lacking position feedback. After upgrading to the REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416. engineers achieved ±0.3 mm ram repeatability over 16-hour shifts—even as oil temperature rose from 30°C to 60°C. The integrated Hall-effect sensor compensated automatically for thermal expansion, while CANopen diagnostics alerted maintenance before failures occurred. Within six months, the plant eliminated scrap losses and extended hydraulic fluid life by 40%. For them, the REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416 wasn’t just a valve—it was a productivity multiplier.

Technical Principles and Innovative Values

Innovation Point 1: True Closed-Loop Spool Control via Hall-Effect Sensing – Unlike conventional proportional valves that only regulate coil current, the REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416 measures actual spool position 1.000 times per second. This enables dynamic compensation for wear, contamination, or fluid viscosity changes—delivering consistent performance over years of operation.

Innovation Point 2: Seamless Transition from Analog to Digital – With native support for both ±10 V and CANopen on the same hardware, this valve bridges legacy PLC systems and modern IIoT architectures. Users can upgrade communication without replacing the valve—reducing retrofit costs by up to 60%.

Innovation Point 3: Cartridge Design for Compact, Leak-Free Manifolds – Mounting directly into NG10 cavities, the REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416 eliminates flanges, hoses, and external manifolds, cutting system volume by 30% and improving response time through reduced dead volume.

Innovation Point 4: Embedded Diagnostics & Predictive Maintenance – The onboard controller logs key parameters (e.g., coil resistance, supply voltage, internal temperature) and reports faults via standardized CANopen EMCY messages. This enables integration into Bosch Rexroth’s ctrlX AUTOMATION or third-party CMMS platforms for condition-based servicing.

Application Cases and Industry Value

A North American aerospace test lab used the REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416 in a fatigue testing rig for landing gear actuators. The valve’s ability to track complex sine-wave profiles at 15 Hz—with less than 1% phase lag—allowed engineers to simulate 30 years of service in under 3 weeks. “It’s the only proportional valve we’ve tested that holds accuracy under continuous high-cycle stress,” said the lab’s chief engineer. Uptime exceeded 99.5% over two years, with zero unplanned replacements.

In another case, a packaging machinery OEM in Italy integrated this valve into a high-speed labeling system requiring synchronized cylinder motion. Using CANopen, they coordinated four REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416 units with a single controller, reducing cycle time by 22% and eliminating mechanical cam wear. Customers reported a 30% drop in maintenance calls post-installation.

Installation, Maintenance, and Full-Cycle Support

Installing the REXRTOH SYHNC100-NIB-2X W-24-P-D-E23-A012 R900978416 requires adherence to Bosch Rexroth’s cavity specifications (NG10 / ISO 4401-05-04-0-05). Torque the valve to 100 ±5 Nm using a socket wrench, and ensure hydraulic fluid cleanliness meets ISO 4406 Class 18/16/13 or better. For CANopen operation, assign a node ID via SDO write (index 0x2000. sub-index 1); for analog mode, calibrate zero/span using Bosch’s free SYHNC Configurator software or manual potentiometers.

Routine maintenance involves visual inspection of the M12 connector seal and periodic verification of zero bias drift—typically <0.2% per year under normal conditions. Should a fault occur (e.g., “EMCY 0x8110: Spool Not Moving”), the valve’s self-diagnostic log helps distinguish between electrical, mechanical, or contamination issues. Field replacement takes under 8 minutes with standard tools, and no re-commissioning is needed if parameters are backed up externally.
