30 mm Incremental Rotary Encoders (Shaft Type) E30S Series

Product Overview

The E30S series incremental rotary encoders are designed with a compact Ø30 mm housing, making them ideal for installation in confined or limited spaces. The low inertia of the shaft ensures minimal impact on the rotation of the connected equipment. These encoders are available with various control output options, allowing for flexible integration into different systems.

Key Features

• Compact Design: The Ø30 mm housing and Ø4 mm solid shaft allow for easy installation in tight spaces, perfect for applications with limited room.
• Low Shaft Inertia: The reduced shaft moment of inertia minimizes resistance, ensuring efficient and accurate rotational performance.
• High Resolution Options: Offering resolutions up to 3000 pulses per revolution (PPR), the E30S series provides precise feedback for various applications.
• Versatile Output Options: Available in Totem pole, NPN open collector, voltage, and line driver outputs to meet different control requirements.
• Flexible Power Supply: The encoders support both 5 VDC ± 5% and 12-24 VDC ± 5%, providing compatibility with a wide range of power sources.
