RA4-QR24

Overview

The Turck RA4-QR24 is a non-contact inductive encoder designed for precise detection of speed, direction, position, angle, and length. It features a wear-free design capable of withstanding harsh environmental conditions. The device supports incremental or absolute position detection and offers high resolution capabilities, including up to 18 bits for absolute models and up to 36,000 pulses per revolution for incremental versions, ensuring reliable performance in demanding industrial applications.

Feature Summary

• Non-contact inductive measurement principle eliminates mechanical wear and ensures maintenance-free operation
• Robust construction withstands severe environmental conditions and extreme operating stresses
• High precision and repeatability suitable for critical positioning and angular feedback tasks

Applications

• Crane boom angle monitoring for load torque limit measurement
• Buffer conveyor monitoring in food processing machinery
• Core shooter machine cycle time optimization via IO-Link integration

Procurement Notes

Verify the specific output type (analog, incremental, CANopen, or IO-Link) required for your application, as the RA4-QR24 series encompasses multiple variants. Confirm the mounting configuration and cable length specifications match your installation constraints. Ensure compatibility with your control system's input requirements before finalizing the order.

Selection Notes

Select this encoder when traditional mechanical encoders fail due to vibration or misalignment issues. The non-contact design allows for flexible mounting without rigid couplings. Choose based on the necessary resolution and signal interface, considering that fixed resolution options are available for simplified configuration without manual teaching.
