Overview
The Schaevitz R120LC OEM Rotary Position Sensor is a precision-engineered, non-contact angular displacement transducer designed for integration into industrial control systems, aerospace actuation modules, medical device positioning mechanisms, and high-reliability test instrumentation. Based on proven variable-reluctance or magnetoresistive sensing architecture (configuration dependent on OEM specification), the R120LC delivers robust analog output proportional to shaft rotation angle across its full mechanical range. Unlike potentiometric alternatives, this sensor eliminates wear-related drift and contact noise—critical for long-term stability in unattended or mission-critical applications. Its compact cylindrical housing, axial through-hole mounting design, and absence of internal bearings make it suitable for direct coupling to rotating shafts without additional couplings or alignment hardware. The device operates over an extended temperature range (–40 °C to +125 °C) and maintains performance under shock (50 g) and vibration (20 g RMS, 10–2000 Hz), meeting MIL-STD-810G environmental compliance requirements for embedded use.
Key Features
- True OEM-grade form factor with standardized 3-pin or 4-pin radial cable exit (configurable per customer interface requirements)
- High-resolution angular measurement with typical linearity error ≤ ±0.25% FS (full-scale) and repeatability < ±0.1% FS
- Output options include ratiometric 0.5–4.5 V DC, 4–20 mA current loop, or PWM signal—compatible with PLCs, DAQ systems, and microcontroller-based controllers
- Hermetically sealed housing rated IP67 for resistance to dust, moisture, and incidental fluid exposure
- EMI-hardened design compliant with EN 61000-6-2 (immunity) and EN 61000-6-4 (emission) standards
- RoHS-compliant construction with lead-free terminations and halogen-free cable jacketing
Sample Compatibility & Compliance
The R120LC OEM sensor interfaces directly with ferromagnetic or diamagnetic target shafts—no external magnets or gears required. It supports both solid and hollow shaft configurations (standard bore diameter: 12.7 mm / 0.5 in, customizable upon request). Calibration is performed at the factory using NIST-traceable angular metrology equipment; each unit ships with individual calibration report documenting zero offset, gain, and thermal coefficient data. The sensor meets ISO 9001:2015 manufacturing controls and is certified to UL 61010-1 for electrical safety in measurement and control equipment. For regulated environments—including FDA-regulated medical devices and FAA-certified avionics—it supports traceable documentation packages aligned with AS9100D and IEC 62304 lifecycle requirements.
Software & Data Management
While the R120LC is a stand-alone analog sensor requiring no embedded firmware, Schaevitz provides OEM customers with comprehensive integration support: pinout schematics, load-line simulation models (SPICE-compatible), and MATLAB/Simulink behavioral blocks for system-level validation. Optional digital interface modules (e.g., USB/RS-485 signal conditioners with onboard linearization and temperature compensation) enable seamless connection to PC-based data acquisition platforms. All calibration certificates and technical documentation are delivered in PDF/A-1b format for long-term archival compliance. Audit trails for production batch records—including material certifications and final test logs—are available under NDAs for GxP-regulated customers.
Applications
- Feedback sensing in servo-controlled robotic joints and CNC rotary tables
- Throttle and flap position monitoring in turbine engine control units (FADEC)
- Angle feedback for MRI gantry tilt mechanisms and radiation therapy collimators
- Rotary encoder replacement in hydraulic valve spool position detection
- Dynamic torsion monitoring in torque-testing rigs and fatigue test frames
- OEM integration into industrial IoT gateways for predictive maintenance analytics
FAQ
Is the R120LC compatible with high-speed rotation?
Yes—the sensor has no moving parts and supports continuous operation up to 10,000 RPM when mechanically mounted within dynamic balance specifications.
Can the output be customized for specific voltage or current ranges?
Absolutely—Schaevitz offers factory-programmable output scaling, zero-offset adjustment, and custom transfer function mapping per OEM requirement.
Does the sensor require external excitation or power conditioning?
It operates from a stable 5 V DC or 8–30 V DC supply (depending on output variant); no external signal conditioning is needed for basic analog output use.
What documentation is provided for regulatory submissions?
Full technical file—including EC Declaration of Conformity, RoHS/REACH statements, calibration reports, and failure mode analysis (FMEA)—is supplied under confidentiality agreement.
Is there a version qualified for explosive atmospheres?
Not as standard; however, intrinsically safe barrier-compatible variants (e.g., with ATEX/IECEx pre-certified signal conditioners) can be developed under joint engineering agreement.
