ROTAPLUS Series I28

Product catalog summary

Materials: The I28 series uses anticorodal (UNI EN AW-6082) for both the flange and housing, and stainless steel (UNI EN 4305) for the non-magnetic shaft. Bearings are ABEC 5 rated.

Electrical Specifications: The encoder offers resolutions ranging from 250 to 2048 PPR, with a maximum counting frequency of 100 kHz. It supports Push-Pull, Line Driver, and Universal output circuits, with a power supply range of +5V±5% to +30V. Maximum consumption is 50 mA, and output current per channel is 40 mA. It includes protection against polarity inversion and short-circuits, and complies with EMC standards EN 61000-4-2 and EN 61000-4-4. The optoelectronic life is at least 100,000 hours.

Mechanical Specifications: The encoder has a shaft diameter of 4 or 5 mm, with a maximum shaft loading of 20 N and rotational speed of 3000 rpm. Starting torque at 20°C is typically 0.1 Ncm, and bearings have a minimum life of 109 revolutions. It features a cable output of 1 m and weighs approximately 50 g. Options include additional cable lengths and an M12 plug.

Environmental Specifications: The encoder can withstand shocks of 250 g for 6 ms and vibrations of 10 g from 5-2000 Hz, according to CEI EN standards. It has an IP54 protection rating and operates within a temperature range of -25°C to +85°C.

Product Features: The I28 is a miniature incremental encoder with a 28 mm diameter, suitable for office equipment, electromedical, and light industrial applications. It features a robust metal housing and offers resolutions up to 2048 pulses per revolution.

Order Code: The order code includes options for output circuits, resolution, output signals, supply voltage, shaft diameter, connection position, cable length, and custom versions.
