Optical Encoders

CP-800/900 Series Size-25 Housed Rotary Optical Encoders

Solid or hollow shaft , incremental, sine/cosine, or absolute format

Features & Benefits

Industry-standard size-25 fits/retrofits easily in many applications Both solid– and hollow-shaft models for application flexibility Incremental, sine/cosine, single– and multi-turn absolute versions Shielded ABEC-7 bearings for smooth, long-life operation Rugged aluminum housing with IP65-rated protection Choice of side or rear-exit connector or cable

Options

Special line counts and index Robust solid– or hollow-shaft size-25 rotary optical encoders Custom connector or cable version Sealed bearings (IP65) and housing (IP66) Up to 5 million counts/revolution (max frequency response 4 MHz) Extended temperature range: -25ºC to +100ºC Absolute single turn resolution up to 16-bit Allied Motion’s CP-800/900 series are size-25 (2.5 in. (63.5mm)) rotary optical encoders, available as solid or hollow shaft models with incremental, sine/cosine, absolute (single- or multi-turn) encoding formats. These rugged units have their own bearing system, and are fully enclosed in a metal housing sealed up to IP66. CP-800 models have a solid shaft and are offered with either a square or servo flange. CP-900 models have a hollow shaft design with a hub-shaft accepting up to 0.5”(12.7 mm) shafts. A face mounted spring absorbs installation misalignment. CP-800/900 encoders offer exceptional resolution of up to 5 million counts per rev. or 16-bit absolute (24-bit multi-turn absolute), enabling their use in high precision positioning applications. Custom designs are available to suit special requirements.
