Accu-Coder Model 25T Thru-Bore, Or Model 25H Hollow Bore (Blind)


Features

• 2.5" Opto-ASIC Encoder with a Low Profile (2.0”)
• Bore Sizes Ranging From 0.625” to 1.125”
• Single Replacement Solution For 2.0" to 3.5" Encoders
• Resolutions to 10,000 CPR; Frequencies to 1 MHz
• Versatile Flexible Mounting Options
• RoHS Compliant

Introducing the next generation of high performance encoders - the Model 25T. As contemporary as its appearance, the Model 25T features the largest thru-bore available in a 2.5” encoder, mounting directly on shafts as large as 1.125" (28 mm). With resolutions of up to 10,000 CPR, and Frequencies of up to 1MHz this industrial strength encoder is perfect for fast revving motors. The 25T features the next generation of Encoder Products Company's proprietary Opto-ASIC sensor which provides superior accuracy and precision counts. The injection molded housing, made from EPC's custom blend of nylon composites, is grooved with "cooling fins" and can take the extreme heat of the motion control industry. With sealing available of up to IP66 and many new rugged flexible mounting options, the Model 25T can perform in demanding industrial environments. This revolutionary new 2.5” encoder truly is unlike any other.
