Pepperl+Fuchs RHI90N-0NAABR61N-02048 Introduction

General Information

Manufacturer: Pepperl+Fuchs, a global leader in industrial automation sensors, recognized for precision and ruggedness in harsh environments.

Type: Incremental rotary encoder designed to measure rotational motion (angular position, speed, and direction).

Model Breakdown:

RHI90N: Series name (90mm housing diameter, robust industrial design).

0NAABR61N: Configuration code (output type, shaft design, housing material, etc.).

02048: Pulses per revolution (2048 PPR), offering high-resolution feedback.

Technical Specifications

Electrical Characteristics

Power Supply:

10–30V DC (wide-range compatibility with industrial control systems).

Output Type:

RS-422 (differential) or HTL push-pull (depending on configuration), ensuring noise immunity and reliable transmission over long distances (up to 1000 meters for RS-422).

Key Parameters:

No-load Current: ≤70 mA (low power consumption).

Output Frequency: Up to 200 kHz (supports high-speed applications).

Signal Channels: A, B, Z (index) with complementary signals for direction and reference positioning.

Protection: Reverse polarity and short-circuit protection for operational safety.

Mechanical Characteristics

Housing:

Material: Aluminum with a corrosion-resistant finish; stainless steel shaft (1.4305/AISI 303) for durability.

Diameter: 90 mm (compact yet robust for industrial use).

Mass: ~900 g.

Shaft:

Hollow shaft (bore size varies, e.g., up to 45 mm) for direct mounting on shafts, eliminating coupling needs.

Insulation Sleeve (optional): PPS GF40 material for electrical isolation (3 kV rating).

Mounting:

Flange mounting (3.1645 aluminum flange) for secure, vibration-resistant installation.

Environmental & Performance

Protection Rating: IP65 (dust-tight and protected against water jets from any direction).

Temperature Range: -25°C to +85°C (operates in extreme industrial conditions).

Vibration/Shock Resistance: Withstands 10 g (vibration, 10–1000 Hz) and 100 g (shock, 11 ms), ideal for rugged applications.

Functional Safety:

MTTFd (Mean Time To Failure): 140 years (high reliability for safety-critical systems).

Mission Time (TM): 20 years.
