Low Profile Incremental Encoder Opto-ASIC Miniature Frameless Caliper
Ideally suited for integration into motors or other tight packaging constraints, the BEI Duncan MOD 700 Series introduces a highly miniaturized rotary incremental
encoder that accommodates a broad range of standard code disk resolutions and diameters. The MOD 700 incorporates BEI's proven Opto-ASIC technology - a phased array photo diode IC noted for its high tolerance for axial movement, low power consumption and high operating temperature range - into a highly miniaturized lead-frame caliper design, offering resolutions up to 2540 PPR (Pulse Per Revolution). Weighing only 25 grams, the unit includes integral surface mount pads for SMT installation onto PCBs or flexible circuitry. Two integrally molded orientation posts assure correct alignment onto PCB circuitry. Offering maximum versatility and compact size, the MOD 700 can be provided with a wide range of optical disks to accommodate a variety of shaft diameters. Disks can be provided in standard optical radii from 0.375" (9.38mm) to 0.860" (21.5mm). Photolithography film disks are also available as a lower cost alternative and are suited for lower temperature extremes.
