Why Choose the ABB 2TLA020071R7900 RHA 698 Absolute Encoder?
The ABB 2TLA020071R7900, type 20-071-79, is an RHA 698 multi-turn safe absolute encoder designed for integration with ABB Pluto Safety PLC systems. This model combines multi-turn absolute position measurement with a 12 mm hollow shaft and M12 connection, providing a robust sensing solution for safety-related position and speed determination on industrial machinery.
Unlike a single-turn encoder, the RHA 698 multi-turn encoder can provide absolute position information across multiple shaft revolutions. Together with an ABB Pluto programmable safety controller, rotational absolute encoder information can be evaluated using ready-made function blocks in Pluto Manager, enabling position and speed information to form part of appropriately engineered machine-safety functions.
The RHA 698 is designed for demanding industrial environments and provides IP67 enclosure protection, with IP66 protection at the shaft inlet. Its hollow-shaft construction enables direct installation around a suitable rotating machine shaft, while the M12 connection supports practical installation and servicing within ABB Pluto safety-control architectures.

Reliable Multi-Turn Position Monitoring for Industrial Machinery
Multi-turn absolute encoders retain a defined position value across multiple revolutions, making them particularly useful where machine position cannot be represented by a single shaft revolution. The ABB RHA 698 provides this multi-turn measurement capability in a hollow-shaft format suitable for direct mechanical integration with rotating machinery.
When integrated with an ABB Pluto Safety PLC, rotational absolute encoder data can be used for safety-related position and speed determination. ABB provides ready-made function blocks in Pluto Manager for encoder applications, allowing the RHA 698 to form part of appropriately engineered machine-safety functions requiring dependable monitoring of mechanical movement.
Typical Applications
- ABB Pluto Safety PLC systems.
- Safety-related multi-turn position monitoring.
- Safe machine-position and speed determination.
- Rotating machinery requiring absolute position feedback across multiple revolutions.
- Industrial production and processing equipment.
- Material-handling and conveyor systems.
- Automated machinery and positioning systems.
- Packaging and manufacturing equipment.
- OEM machine building and functional-safety systems.
