Incremental Thru-Bore & Motor Mount Encoders
22
Representing the next generation of high performance encoders, the Model 25T features the
largest thru-bore available in a 2.5” encoder, mounting directly on shafts as large as 1.125" or
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 EPC'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.
