Kollmorgen PRD-B040ASIB-6
Model Series: PRD Series (Precision Rotary Devices)
Product Introduction:
The PRD-B040ASIB-6 is a sin/cos resolver from the PRD product family with ASI (Actuator Sensor Interface) output compatibility. The “B040” identifies the specific resolver model variant, “ASI” indicates the output interface type, “B” denotes the electrical configuration revision, and “6” is the firmware/hardware revision level.

Structural Features:
- Compact housing optimized for ASI cable routing
- M12 connector enables single-cable connection (power + data)
- Robust aluminum construction for harsh environments
- ASI output eliminates need for separate RDC in ASI-compatible systems
Working Principle:
Same fundamental resolver principle as PRD-0019000z-0. The ASI variant encodes sin/cos data into the ASI protocol, allowing position data to be transmitted over a single cable along with power to the resolver. Compatible with Kollmorgen AKD and S-series drives with ASI option.
Advantages:
- Single-cable solution reduces wiring complexity
- ASI protocol supports daisy-chaining of multiple sensors
- Absolute position available immediately on power-up
- IP67 rating for washdown and outdoor environments
- Compatible with Kollmorgen AKD servo drives (native ASI support)
Applicable Industries:
- Food and beverage processing (washdown)
- Pharmaceutical manufacturing
- Packaging machines
- Material handling in cold storage
- Outdoor automation equipment
Installation Requirements:
- Mount using 2x M4 mounting holes on 30 mm bolt circle
- Maximum shaft overhung load: 15 N radial, 8 N axial
- ASI cable max length: 10 meters (32.8 ft) recommended
- Terminate ASI bus with 120 Ω resistor at last device
Usage Notes:
- Must be used with an ASI-compatible drive (e.g., Kollmorgen AKD with ASI option card)
- Do not mix ASI and non-ASI resolvers on the same bus segment
- Verify ASI address setting via drive parameters before commissioning
