Pepperl+Fuchs RHI90N-0HAAAR61N-01024 Introduction

General Information

Manufacturer: Pepperl+Fuchs, a renowned global provider of industrial automation solutions, specializing in rugged and reliable sensors.

Type: Incremental rotary encoder designed to measure rotational speed, position, and direction with high precision.

Model Breakdown:

RHI90N: Series identifier (90mm housing diameter, industrial-grade construction).

0HAAAR61N: Configuration code (output type, shaft design, housing material, etc.).

01024: Pulses per revolution (1024 PPR), balancing resolution and operational speed.

Technical Specifications

Electrical Characteristics

Power Supply:

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

Output Type:

RS-422 (differential) or TTL/HTL push-pull (depending on configuration), ensuring robust noise immunity and long-distance signal transmission (up to 1000 meters for RS-422).

Key Parameters:

No-load Current: ≤70 mA (energy-efficient operation).

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

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

Protection: Reverse polarity and short-circuit protection for safe operation.

Mechanical Characteristics

Housing:

Material: Anodized aluminum for corrosion resistance; stainless steel shaft (1.4305/AISI 303) for durability.

Diameter: 90 mm (compact design for space-constrained installations).

Mass: ~900 g.

Shaft:

Solid shaft or hollow shaft (bore size varies, e.g., up to 45 mm) for direct mounting, reducing coupling complexity.

Mounting:

Flange mounting (3.1645 aluminum flange) with vibration resistance (meets IEC 60068-2-6 standards).

Environmental & Performance

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

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

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

Functional Safety:

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

Mission Time (TM): 20 years.
