I/55 Standard Incremental Encoder

I/55 – Standard Incremental Encoder, Shaft Ø 6×10 mm, Body: Ø 55×56 mm, Pulse range: 1 to 2,540

The incremental encoder ELCIS I/55 is designed for industrial environments where a reliable, medium-sized, high-performance solution is required. With a body of Ø 55 mm and solid axle of Ø 6 mmThis model provides mechanical stability, signal accuracy and long service life, even under demanding working conditions.

The I/55 supports resolutions from 1 to 2,540 pulses per revolution (ppr), with feeding between 5 and 28 V DC, allowing its integration into a wide range of control systems. It offers multiple electrical output types such as push-pull, line driver, NPN, PNP, or open collector. Thanks to its optical system with long-life LEDs and precision bearings, it is capable of generating clean signals up to 100 kHz, supporting speeds up to 6,000 rpm.

This encoder is prepared for hostile industrial environments, with vibration protection up to 12 G, impacts of 50 G, and temperatures from 0°C to +70°C. Its mid-size format makes it ideal for applications where increased performance is required without excessively increasing the device's volume.
