RE520 - REM520 Round flanged incremental encoders

Product catalog summary

Mechanical & Environmental Specifications
The incremental rotary encoders, models RE/REM 520, 530, and 540, feature an aluminium housing and AISI 303 steel shaft. They weigh approximately 400 grams and support shaft diameters of 6, 8, 9.52, 10, and 11 mm. The encoders can operate continuously at 6000 revolutions per minute (rpm) and temporarily at 10000 rpm, with a starting torque of ≤0.8 Ncm and inertia of ≤25 g cm². They can withstand axial loads up to 80 N and radial loads up to 100 N. The encoders are resistant to vibrations (100 m/sec²) and shocks (50 G for 11 ms). They have a protection degree of IP65, with an optional IP66 when a sealing ring is applied. The operating temperature range is -10 to 70°C, and the storage temperature range is -20 to 80°C.

Electrical & Operating Specifications
The encoders use an incremental pulse code with pulses per revolution ranging from 2 to 12500 for RE models and 8 to 2048 for REM models. They provide two square wave output signals 90° ±15° out of phase, with a zero reference pulse per revolution. The electronic outputs include push-pull, NPN open collector (RE only), and line driver options, all protected against short circuits. The supply voltage is 5/30 Vdc, with protection against polarity reversal, and the maximum absorption is 30 to 80 mA. The maximum frequency is 100/200 KHz for pulses per revolution greater than 1250. Connections are available via axial or radial cables or MS connectors.

Mechanical Versions
The encoders are available in several mechanical configurations, including servo coupling and synchro flange, with a body and flange diameter of 58 mm. The centering mask diameter varies between 36 mm and 50 mm, depending on the model. Shaft diameters are available in 6, 8, 9.52, 10, and 11 mm.

Pulses Per Revolution
The RE series offers a wide range of pulses per revolution, from 2 to 12500, while the REM series ranges from 8 to 2048. Specific pulse values are available for each series, catering to different application needs.

Ordering Information
The encoders can be ordered with different output signals (push-pull, NPN open collector, line-driver), shaft diameters, and supply voltages. They are available with or without a zero pulse, and connection options include axial or radial positions with various sealing configurations.
