Model 725 Size 25 Accu-Coder™ optical shaft encoder is specifically designed for the challenges of an industrial environment. But don’t let its tough, industrial package fool you; it still has the performance to reach resolutions up to 30,000 cycles per revolution. The Model 725 is available with both flange and servo mounting options, along with two distinctive 2.5" diameter housing styles. The rugged Standard Housing isolates the internal electronics from the shock and stress of the outer environment. The extra heavy-duty Industrial Housing features a fully isolated internal encoder unit that prolongs bearing life by using a flexible mount to protect the encoder from severe axial and radial shaft loading. Refer to Technical Bulletin TB-118 to see why this is the most robust Size 25 unit available.
