The AEDR-850X is the world's smallest 3-channel reflective incremental encoder with digital outputs, utilizing reflective technology for motion control. Designed for operation between -20C and 85C, it is suitable for commercial and industrial applications. Its ultra-compact size (3.95 mm L 3.4 mm W 0.9562 mm H) makes it ideal for miniature applications where space is critical. The encoder offers two-channel quadrature digital outputs for direction sensing and a third channel for index digital output. Its TTL compatibility allows direct interfacing with most signal processing circuitries, providing excellent design flexibility and integration ease.
