Model Code Breakdown (KF47DRE90L4BE2HR/ASB4/TH)Every suffix in the part designation tells you exactly what hardware options are integrated into this assembly:

• KF47: The gearbox family. It is a Helical-Bevel Right-Angle reducer designed for high efficiency (>90%) and a long mechanical life. The "F" signifies it includes a B5 output flange for mounting.
• DRE90L4: The high-efficiency AC asynchronous induction motor. The "90L" refers to the IEC frame size, and the "4" indicates a 4-pole configuration (delivering the standard 1740 RPM synchronous base speed at 60 Hz).
• BE2HR: The integrated mechanical safety brake package. It features a BE2 brake paired with a manual brake release ("HR" for hand release), allowing you to manually free the motor shaft when unpowered.
• ASB4: The connection type, typically referencing a heavy-duty, plug-and-play industrial connector socket (such as Han-Modular or plug connector variants) on the motor terminal box for quick deployment.
• TH: Built-in Thermistors (positive temperature coefficient thermistors) integrated into the windings to provide advanced thermal protection against overheating or motor stalls.
