Kubler 8.5878.552F.2113 Absolute Encoder

KUBLER 8.5878.552F.2113 Sendix 5878 Absolute Encoder

The KUBLER 8.5878.552F.2113 (Alternative MPN: 85878552F2113) is a heavy-duty optical absolute singleturn encoder belonging to the robust Sendix 5878 series. Designed explicitly for high-precision angular feedback in demanding industrial and marine environments, this unit integrates optical scanning technology with an advanced CANopen fieldbus interface. It features a 14 mm blind hollow shaft coupled with an integrated stator coupling, ensuring high tolerance against mechanical misalignments and thermal expansion variations in dynamic machinery setups.

Key Features

1. High-Resolution Singleturn Feedback: Delivers a maximum resolution of 16 bits distributed across a full 360-degree rotation cycle for pinpoint positional accuracy.
2. Robust Optical Sensing Technology: Immune to magnetic field interference, providing stable, reliable performance in high-EMF industrial electrical rooms and motor drives.
3. Integrated Stator Coupling: Compensates for radial and axial play on motor shafts, preventing premature bearing fatigue and operational failure.
4. Advanced CANopen Fieldbus Connectivity: Features dual radial M12 connectors enabling seamless daisy-chain network integration, reducing overall wiring complexity.
5. Extreme Environmental Endurance: Sealed to IP67 standards with a wide operational temperature envelope of -40°C to +80°C, suitable for outdoor, offshore, and mobile machinery applications.

Compatibility

• Compatible Drive Systems & PLCs: Siemens S7-1200/1500, Beckhoff CANopen nodes, ABB drives, Schneider Electric motion controllers, and Woodward marine engine control systems.
• Mechanical Interfacing: Standard 58 mm housing profile engineered to retrofit directly onto standard B5/B14 motor end-bells and marine winch feedback assemblies.

Frequently Asked Questions

What is the default node ID and baud rate for the Kubler 8.5878.552F.2113?

The default node address and baud rate are typically configured via onboard hardware settings (rotary switches or DIP switches) underneath the protective cover, or software-programmable via the CANopen object dictionary depending on your system requirements. Consult the operation manual for specific factory presets.

Can this encoder withstand direct exposure to salt spray and washdown conditions?

Yes. With an IP67 protection class, the encoder housing and shaft inputs are completely protected against dust ingress and temporary water immersion, making it fully operational in corrosive marine decks and industrial washdown spaces.

Does this absolute encoder require homing routines after a power loss?

No. Because it uses absolute singleturn optical measurement technology, it immediately outputs the exact angular position upon power restoration without requiring a mechanical zero-reference or homing cycle.

What kind of mechanical coupling is recommended if the stator coupling needs replacement?

The unit comes equipped with an integrated stator coupling. Avoid rigid direct-bolting without compliance elements, as misalignment will transfer excessive load to the internal optical disk bearings, leading to premature drift or failure.
