Pepperl+Fuchs RHI90N-0NAK1R61N-01024 incremental rotary encoder

Pepperl+Fuchs RHI90N-0NAK1R61N-01024 is an incremental rotary encoder manufactured by Pepperl+Fuchs. Below is a detailed introduction in English:

Product Overview

Series: RHI90N series, known for high precision and reliability in industrial applications.

Type: Incremental encoder, which converts mechanical quantities (e.g., angular displacement, rotational speed) into electrical pulses via optoelectronic technology.

Applications: Widely used in industrial automation to measure angle, position, speed, and direction. Typical industries include manufacturing, metallurgy, textiles, paper processing, and logistics, where it monitors and controls motors, drive shafts, and other rotating components.

Working Principle

The encoder operates on an optoelectronic principle:

A rotating code disk with light-transmitting and light-blocking patterns is paired with a light source and photoelectric sensors.

As the shaft rotates, the code disk modulates the light beam, and the sensors generate electrical signals (A/B phase pulses with a 90° phase difference). These pulses enable speed measurement and direction detection (via pulse sequence analysis).

Technical Specifications

Parameter Details

Resolution (PPR) 1024 pulses per revolution, providing fine angular measurement precision.

Output Type Typically supports multiple outputs (e.g., voltage output, open collector, push-pull, line driver) for compatibility with various control systems.

Power Supply 10–30V DC (standard industrial voltage range).

Protection Class IP65, protecting against dust ingress and water jets from all directions.

Operating Temperature -25°C to +85°C, suitable for harsh industrial environments.

Mechanical Shaft Designed for robust mechanical integration (specific shaft dimensions vary by model).
