40 mm Incremental Rotary Encoders (Shaft Type) E40S Series

Product Overview

The E40S series shaft type incremental rotary encoders are designed for high precision in rotational measurement within a compact Ø40 mm housing. These encoders are ideal for applications with limited installation space, thanks to their easy-to-install design. The low shaft moment of inertia reduces interference with the rotation of the attached equipment, ensuring reliable and accurate performance. Multiple control output options are available to suit various application needs, making the E40S series a versatile choice for your rotary encoder requirements.

Key Features

• Compact Design: The Ø40 mm housing allows for installation in tight or confined spaces, making the E40S series suitable for a wide range of applications.
• Low Shaft Moment of Inertia: Minimizes the impact on the rotation of connected equipment, ensuring precise and stable operation.
• High Resolution Options: Available in various resolutions ranging from 1 to 5000 pulses per revolution (PPR) to meet different precision requirements.
• Multiple Control Output Types: Choose from Totem pole output, NPN open collector output, voltage output, or line driver output, depending on your application needs.
• Flexible Power Supply: The encoders support both 5 VDC ± 5% and 12 - 24 VDC ± 5% power supplies, providing flexibility for integration into different systems.
• Durable Construction: Designed to handle a maximum allowable revolution of 5,000 rpm, with a radial load capacity of ≤ 2 kgf and a thrust load capacity of ≤ 1 kgf.
