Description
1. At-A-Glance Executive Brief
- Model: R902477806
- Brand: Bosch Rexroth
- Part Type: Inductive Position / Linear Stroke Transducer (AWAX004D09)
- Lifecycle Status: Factory Discontinued / Legacy System Replacement
- Weight: 0.56 kg
2. Technical Introduction
A failing feedback sensor on a high-pressure axial piston pump or industrial hydraulic cylinder causes erratic swashplate positioning and unstable flow output, shutting down automated production.
This inductive displacement transducer mounts directly onto heavy industrial fluid power assemblies to provide continuous, high-resolution position tracking without mechanical wear. Operating on an electromagnetic principle, it converts linear physical movement into precise electrical feedback signals for the machine controller or PLC rack.
- Best Suited For: Rexroth variable displacement pumps, industrial hydraulic actuators, and precision press lines.
3. Core Technical Specifications
- Manufacturer: Bosch Rexroth
- Model Designation: AWAX004D09

- Please refer to the OEM datasheet for complete environmental tolerances.
4. Field Engineer’s Tech Notes
- Mechanical Alignment and Stroke Limits: When mounting this linear transducer onto a pump control or hydraulic cylinder, ensure the core alignment matches the exact stroke dead-center. Bottoming out the probe rod during mechanical assembly will fracture internal inductive coils and instantly ruin the sensor.
- Shielded Cabling and Signal Interference: Position feedback lines run close to high-current PWM proportional valve wiring in many industrial setups. Always use proper foil-shielded twisted-pair cable with the drain wire grounded exclusively at the control cabinet end to prevent erratic position readings or analog jitter.
5. Adaptive QA & Testing Protocol
Our testing procedure for inductive feedback devices involves full bench-top excitation voltage checks, zero-point offset verification, and stroke simulation across the linear measurement range. Output voltage or current loops are monitored using high-speed data acquisition tools to verify smooth signal tracking without dropouts. Detailed calibration and functional test reports are available upon request to satisfy internal plant quality assurance requirements.
6. Buyer’s FAQ
- What is the standard warranty coverage for this transducer?All New Surplus (NSFP) and refurbished units include a comprehensive 12-month operational warranty from the invoice date.
- Are lead times affected by factory obsolescence?Because this part is designated as discontinued by the manufacturer, we maintain dedicated stock for immediate dispatch to bypass extended sourcing delays.
- Is this a direct drop-in replacement for older AWAX004D09 units?Yes. This part number maps directly to the original equipment specification, maintaining identical mechanical dimensions and electrical pinouts.
