Product catalog summary

Ordering Code and Model Specifications
The document provides detailed ordering codes for Eltra's measuring wheels, including models RH200, RL500, and RM500. Each model is associated with specific wheel surfaces, resolutions, zero pulse options, power supplies, electronic interfaces, shaft diameters, enclosure ratings, maximum rotation speeds, output types, and direction types. Custom variants are also available.

Main Features
The measuring wheels are designed for industrial applications requiring linear movement measurement, such as in continuous sheet cutting machines. They feature an aluminum body, an oscillating arm, and a self-lubricating compact box for long-term operation without maintenance. The wheels ensure stable contact with materials for accurate length and speed measurements. Available surfaces include crossed-knurl aluminum and anti-oil or anti-sliding rubber.

Electrical Specifications

RH Series: Resolutions from 50 to 1024 ppr, power supply options of 5 V DC or 8/24 V DC, and a maximum output frequency of 100 kHz.
RL Series: Resolutions from 10 to 2500 ppr, power supply options of 5 V DC, 5/28 V DC, or 8/24 V DC, and a maximum output frequency of 220 kHz.
RM Series: Resolutions from 1 to 10000 ppr, similar power supply options as RL, and a maximum output frequency of 250 kHz up to 6000 ppr and 500 kHz from 7200 ppr.

All series comply with IEC 61000-6-2 and IEC 61000-6-4 electromagnetic compatibility standards.

Mechanical Specifications
The document details mechanical specifications such as shaft diameters (8/10 mm), enclosure ratings (IP 54, IP 64, IP 66), maximum rotation speed (3000 rpm), shock and vibration resistance, starting torque, and materials used for body, housing, shaft, support, and wheel. Operating and storage temperature ranges are also provided.

Resolutions
Each series has specific resolution options, with preferred resolutions highlighted in bold. The RH series offers resolutions from 50 to 1024 ppr, the RL series from 10 to 2500 ppr, and the RM series from 1 to 10000 ppr.

Connections
The document includes detailed connection information for various output types and connector configurations, including pin assignments for different connectors such as JIS-C-5432, Amphenol, M12, and IEC 60130-9.

RH 200 A / B / C RL - RM 500 A / B / C-1

MEASURING WHEELS MAIN FEATURES Measuring wheel series designed for specific industrial applications where is required to measure a linear movement (i.e. continuous sheet cutting machines of wood, textiles, glass, etc.). The body is entirely designed of aluminium and mounted using an oscillating arm pivoted on the shaft. It comes with an integrated self-lubricating compact box to assure a long operation period without any maintenance. The weight of the metric wheel keeps a stable contact with the material, allowing an accurate measurement of both length and speed. Wheel surface can be in crossed-knurl aluminium, special anti-oil or anti-sliding rubber. • 3 channel encoder (A / B / Z) up to 10000 ppr • Power supply up to +28 VDC with several electronic interfaces available • Up to 500 kHz output frequency • Model RM with internal coupling • Cable or connector output MODEL 200 mm measuring wheel - RH series RH200 500 mm measuring wheel- RL series RL500 500 mm measuring wheel - RM series RM500 WHEEL SURFACE smooth A knurled B rubberized C without wheel / RESOLUTION (mod.
