Eltra EL40A100Z5/28N6S3PSA2 Incremental Rotary Encoder

The ELTRA EL40A100Z5/28N6S3PSA2 is a 100 PPR optical incremental encoder with a 6 mm solid shaft and IP66-rated housing, built for precise rotational feedback in industrial automation and motion control. It offers A, B, and Z outputs (NPN) from a 5 to 28 VDC supply, with a Z channel for zero reference, and a compact 42 mm housing with axial cable output. Mounting uses a 20 mm clamping flange and features a PA66 glass-fiber-reinforced housing with aluminum ball bearings for rugged operation; the 6 mm shaft is designed for direct coupling to servo motors and driven equipment. The unit supports up to 3000 RPM and up to 150–250 kHz maximum output frequency, depending on configuration, making it suitable for servo drives, conveyors, packaging lines, assembly machines, and labeling systems where accurate position, speed, and direction data are essential.
