Product Overview:
The PRD-0039050E-3 is a custom-configured resolver feedback device manufactured to Kollmorgen’s precision specifications. It is typically supplied as an OEM component integrated into motor assemblies or custom machine axes where standard catalog resolvers do not meet mechanical or electrical requirements.
Technical Specifications:

| Excitation Voltage | 4.5–7.0 Vrms |
| Excitation Frequency | 2.5 kHz – 10 kHz |
| Output Signals | Sin θ, Cos θ (analog, ratiometric) |
| Accuracy | ±2 arc-min (±0.033°) electrical |
| Linearity | ±0.03% FS |
| Max Speed | 8,000 RPM (continuous) |
| Shaft Diameter | 8mm solid shaft (custom per revision 3) |
| Shaft Length | 25mm |
| Connector | M23 8-pin, angled (E-config) |
| Operating Temperature | -40°C to +125°C |
| IP Rating | IP67 |
| Weight | ~0.25 kg |
| Compliance | CE, UL |
Working Principle:
Electromagnetic induction — stator-mounted excitation winding induces Sin/Cos voltages in rotor winding proportional to shaft angle. Drive-side RDC converts analog signals to digital position.
Structural Features:
- Custom 50mm housing — larger than standard B-402 for higher torque coupling
- 4 pole pairs — provides 2× resolution of 2-pole variant at same mechanical speed
- Angled M23 connector — routing optimized for confined spaces
Advantages:
- Custom mechanical interface — drop-in replacement for OEM-specific resolvers
- 4 pole pairs deliver 4× electrical resolution vs. 2-pole at same RPM
- IP67 + 125°C rating — survives harshest industrial conditions
- Absolute position — zero homing required
Applicable Industries:
OEM Machinery Builders, Custom CNC Builds, Aerospace Actuation, Defense Systems, Heavy Industrial Drives
Installation Requirements:
- Mount with 4× M4 screws on 40mm bolt circle (custom pattern)
- Maximum shaft misalignment: 0.05mm radial, 0.05° angular
- Excitation wiring: twisted pair, shielded, grounded at drive end
