Product Overview

The ENS1J-B28-L00256L is a Rotary Optical Encoder with axial multi-purpose pin terminals and 2-bit quadrature code, channel A leads channel B by 90° (electrical) switching configuration with clockwise rotation. The rotary optical encoder has Ø1/4-inch plain end shaft and 9:00 position anti-rotation lug position. The self-contained rotary optical encoder is suitable for digital systems where both magnitude and direction of adjustment must be provided. The EN encoder is ideal for use as a digital panel control or as a position sensing device in applications where long life, reliability, high resolution and precise linearity are critical.
