RE40 Incremental encoder

Product catalog summary

Overview: The RE40 series are incremental rotary encoders available with or without a zero pulse, offering a range of pulses per revolution from 2 to 12,500. These encoders are housed in metal with an IP65 protection rating, suitable for various industrial applications.

Mechanical Versions: The encoders come in several configurations, including round and square flanges, with shaft diameters of 4 or 6 mm, and hollow shaft options of 6 or 8 mm. They feature anti-rotational fixing and elastic support options, with a standard body diameter of 40 mm.

Mechanical & Environmental Specifications: The encoders are constructed with an aluminum case and AISI 303 steel shaft, weighing approximately 100 grams. They support up to 6000 revolutions per minute, with a starting torque of ≤0.2 Ncm and an inertia of ≤5 g cm². They can withstand axial loads of 10N and radial loads of 20N, with vibration resistance up to 10 G and shock resistance up to 30 G. Operating temperatures range from -10°C to 70°C, with storage temperatures from -20°C to 80°C.

Electrical & Operating Specifications: The encoders provide incremental pulse codes with two square wave outputs 90° ±15° out of phase, and a zero pulse width of 90°±15°. They offer push-pull or line-driver electronic outputs, with supply voltages of 5Vdc or 5/30Vdc, protected against short circuits and polarity reversal. Maximum frequency is 100/150 KHz, with a maximum current absorption of 40 mA.

Ordering Information: The encoders can be ordered with different electronic outputs (push-pull or line-driver), shaft diameters, supply voltages, and pulse per revolution specifications. Connection options include radial cable glands with a 1-meter cable length.

Connections: The encoders feature color-coded cables for output signals, including Out 1, Out 2, and Out Z (for RE41 models), with additional cables for power supply and grounding.
