Industrial 725N-S-S-0500-Q-PU-1-F-1-SG 01.30-N-N S491 Encoder

The Accu-Coder 725N-S-S-0500-Q-PU-1-F-1-SG/01.30-N-N S491 Encoder is an incremental shaft encoder from Encoder Products Company, part of the 725 Accu-Coder family. The 725N variant is a size-25, optical encoder designed for industrial feedback applications and offers servo-mount (S) and flange-mount (F) configurations. Its MFR code indicates A/B quadrature outputs (Q), a pull-up resistor option (PU), and a shielded cable assembly (SG) paired with the 01.30 cable-length designation, with S491 serving as an internal revision/lot identifier. Some records cross-reference IMS-SS-1403 for this model, and distributor listings show this exact variant as discontinued. The 725 family is specified to provide high-resolution feedback, up to 30,000 CPR, making it suitable for precision positioning tasks in automated equipment where a compact form factor and reliable electrical interfacing are required.
